The invention relates to electrical measuring technology and can be used as a portable device for monitoring the operation of various electrical installations during commissioning, installation and operational work in various areas national economy. The purpose of the invention is to expand the functionality and increase the reliability of the device. For this purpose, the universal probe contains a voltage monitoring unit, a resistance indication circuit, including resistors, transistors, light-emitting elements, and a zener diode. What is new in the device is that the resistance indication circuit includes a current amplifier made on the first and second transistors according to the emitter follower circuit, and a voltage monitoring circuit is connected to the base of the first transistor and between the base of the first transistor 4 and the collectors of the first and second transistors 4, 5, a zener diode 8 is connected.

The invention relates to electrical measuring equipment and can be used as a portable device for monitoring the operation of various electrical installations during commissioning, installation and operational work in various areas of the national economy. The universal probe PU-82 is known. The probe consists of three main components: an input amplifier, a voltage-controlled generator, and a voltage presence indication terminal. The disadvantage of the device is its complexity in manufacturing and repair, low functionality, and the use of expensive components, namely three microcircuits. A probe of type UP-71 is known. The probe circuit consists of the following main elements: DC amplifiers assembled on transistors, an amplitude limiter with a rectifier and filter consisting of diodes, zener diodes and a capacitor, limiting input resistance, additional resistance, indicator lights. The disadvantage of the device is its low functionality, since the device does not indicate the presence of voltage in electrical circuits that are known to be energized, and serves only to determine the integrity of the electrical circuit. The device is uneconomical, since expensive components are used in its manufacture. In addition, the integrity of the electrical circuit inside the device is disrupted as a result of the contact of the sliding contacts of the probe, which is installed in the working position. The purpose of the invention is to expand the functionality and increase the reliability of the device. To do this, in a universal probe containing a circuit for monitoring the presence of voltage, a resistance indication circuit, including resistors, transistors, light-emitting elements, a zener diode, a current amplifier is connected to the resistance indication circuit, made on the first and second transistors, according to the emitter follower circuit, and to the base of the first The transistor is connected to a voltage monitoring circuit and a zener diode is connected between the base of the first transistor and the collectors of the first and second transistors, and a light-emitting element is connected to the emitter circuit of the second transistor, to which a DC power source is connected in series, the second output of which is connected to the collector of the second transistor. In addition, the connection between the detachable probe and the probe circuit is carried out through a threaded connection. An emitter follower is widely known, for example, in radio engineering devices as a buffer or matching stage between circuits with high output impedance and circuits with high input capacitance and low input impedance. In this case, the use of an emitter follower with a load in the emitter circuit in the form of a light-emitting element (LED) makes it possible to increase the sensitivity of the circuit, and this expands the range of values ​​controlled by the probe. The proposed device circuit is reliably protected from breakdown in case of accidental exposure to voltage, since the collector-emitter junction is under the same potential as a result of connecting a DC power source in series to the light-emitting element in the emitter circuit of the second transistor, and the second terminal of the power source is connected to the collector second transistor. The design of a detachable probe with a thread at the end ensures reliable uninterrupted operation of the device as a result of eliminating the violation of the integrity of the electrical circuit of the device when installing the probe in the working position. A comparative analysis of the proposed solution with the prototype showed that the claimed solution is distinguished by the use of an emitter follower in the resistance indication circuit with a load in the emitter circuit in the form of a light-emitting element. This allows us to conclude that the proposed solution meets the “novelty” criterion. A comparative analysis of the proposed solution with other known solutions in this field did not allow us to identify devices with a similar set of features. This allows us to conclude that the proposed solution meets the criteria of the invention." significant differences". The drawing shows circuit diagram devices. The device contains a circuit for monitoring the presence of voltage, which consists of light-emitting elements 1 and 2, connected in parallel and counter, and a resistor 3. LEDs of the AL 307VM type, green and red, respectively, are used as light-emitting elements 1 and 2. The circuit for indicating the resistance of the controlled circuit includes a current amplifier assembled using a two-stage emitter follower system, namely transistors 4, 5 (for example, based on MP-25 type triodes), with a load in the emitter circuit of transistor 5 in the form of a light-emitting element 6. As Light-emitting element 6 uses a yellow LED AL 307VM. Resistor 7 and zener diode 8 (type D814A) protect the input of the current amplifier from unacceptable voltage levels. The device circuit contains a traditional probe, including an alligator clip 9 connected by a flexible wire 10 to the circuit, an incandescent lamp 11 (2.5 V), a DC power source 12 (for example, two A332 elements), a detachable probe 13. For connection with electronic circuit The device has a clamp with threaded elements 14, as well as a microswitch 15 (for example, MP 210203) with 16 normally closed and 17 normally open contacts. Detachable probe 13 is made with a thread at the end. Thanks to this, the probe 13 is screwed into the threaded elements 14 of the clamp, making reliable contact. The universal probe circuit is assembled on an insulating board, placed in a detachable plastic case for protection from mechanical damage (not shown in the drawing). The device works as follows. It is first necessary to check the serviceability of the circuit and its readiness for operation. To do this, screw the probe 13 into the threaded elements 14 of the clamp until it stops. In this case, the leakage current of the amplifier, which includes transistors 4, 5 (I Y = l Y4 x K 4 x K 5, where K 4 and K 5 are the gains of the first and second stages), gives the threshold radiation of the yellow color of the light-emitting element 6. The device is working properly and ready to go. When checking resistors, one terminal of the resistor is connected to terminal 9, and the other to probe 13. In this case, through resistor 7, the negative potential of power source 12 is supplied to the base of transistor 4, which opens the base-emitter junction, and the potential flows to the base of transistor 5. Leaks base current l B4 along the minus circuit of power source 12 - probe 13 - resistor 7 - base of transistor 4, base of transistor 5 - light-emitting element 6 - normally closed contact 16 of microswitch 15 - "plus" of power source 12. The base current l B4 opens the collector-emitter junction of transistor 4, and current l B4 x K 4 flows through the minus circuit of power source 12 - probe 13 - collector-emitter junction of transistor 4 - base-emitter transistor 5 - light-emitting element 6 - normal closed contact 16 of microswitch 15 is the “plus” of power source 12. The current of the first stage l B4 x K 4 opens the collector-emitter junction of transistor 5, and the flowing current l B4 x K 4 x K 5 along the minus circuit of the power source 12 - probe 13 - collector-emitter junction of transistor 5 - LED 6 - normal closed contact 16 of the microswitch 15 - the “plus” of the power source 12 causes the light-emitting element 6 to emit yellow light. The brightness of the radiation determines the serviceability of the controlled resistor. If there is no jump in the brightness of the radiation, then there is either a break in the resistor or it is more than 5 MOhm. In comparison with the brightness of radiation, similar in value to a known good resistance, one can judge the value of the resistance. In the same way, the serviceability of capacitors is checked, and, judging by the time and amount of charge or discharge, the value of their capacitance in comparison with the brightness of the radiation when checking a known-good capacitor, known by the size of the capacitance. So, if the yellow light-emitting element 6 emits threshold light, the capacitor has a break; if element 6 constantly emits maximum light, the capacitor is broken. The insulation of electric motor windings in relation to its body is checked in the same way. If a jump in the emission stage of the light-emitting element 6 is noticed, then the motor winding is wet, less than 0.5 MOhm, and the motor must be dried; if not, voltage can be applied. When checking for the presence of a voltage above 6V, zener diode 8 is triggered, shunting the input of transistor 4. Voltage is supplied to light-emitting elements 1 and 2 through resistor 3. When an alternating voltage is applied, both light-emitting elements 1 and 2 emit green and red light. When a constant voltage is applied, if there is a negative potential on the probe 13, the light-emitting element 1 emits green light, the element 2 is locked. If the probe shows a positive potential, light-emitting element 2 emits red light and element 1 is locked. To check electrical circuit diagrams for integrity, terminal 9 is connected to one end of the circuit. Without pressing the microswitch, find the second end of the circuit based on the maximum brightness of the light-emitting element 6. Press the microswitch 15, closing contact 17. This puts the traditional probe circuit into operation. If lamp 11 is bright, then the resistance is less than 10 Ohms and the circuit is intact, i.e. the second end of the chain is found correctly. Thus, the universal probe allows you to expand the scope of application compared to existing ones. The technical and economic efficiency of the invention lies in increasing the efficiency and reducing the cost of the device by simplifying the design and eliminating the use of expensive components containing precious metals. The device is easy to use.

Even many experienced summer residents often confuse a cultivator and a walk-behind tractor, implying that these are the names of the same item.

However, what is the difference between a walk-behind tractor and a cultivator? Both of these types of equipment are used for agricultural work, but they have different purposes:

• A cultivator, as you might guess from the name, its main function involves cultivating (cultivating) the land. It is equipped with special cutters that carry out plowing and loosening of the soil.
• A walk-behind tractor is a mechanism whose purpose depends on what attachments are installed on it. It itself is a mechanism with an engine that brings this equipment into working condition. Thus, it can serve as a snow blower or a rotary mower.

A walk-behind tractor can equally well perform the functions of a cultivator, while the latter has a narrow specialization consisting only of soil cultivation.

You should also dwell on the technical nuances:

• Walk-behind tractors are heavier than cultivators;
• They are characterized by the presence of a reinforced body, gearbox and handle;
• The standard walk-behind tractor usually has pneumatic wheels, while the basic configuration of the cultivator does not include them.

The only thing common between walk-behind tractors and cultivators is demand. Both of these types of gardening equipment are extremely in demand among farmers and gardeners. GardenGear offers cultivators and walk-behind tractors of exceptional quality from trusted manufacturers at the best prices in this segment.
