Technical characteristics

E42701 ammeter, voltmeter E42701, E42701 kiloampermetr (E-42701, E 42701)
 
E42701 ammeter, voltmeter E42701, E42701 kiloampermetr designed to measure current and voltage in AC circuits.
Dimensions - 60h60h50mm.
Class of accuracy - 1.5-2.5.
Vibration, tryaskoprochny, impact resistant.
 
Technical characteristics of the devices E42701 ammeters, voltmeters, E42701, E42701 kiloampermetry:
 
The devices are designed to measure current and voltage in AC circuits over a wide frequency range.
Panel meters ammeter E42701, E42701 voltmeter, kiloampermetr E42701 for measuring AC current and voltage are available in two forms:
- Magneto system with a rectifier;
- Electromagnetic system.
Devices E42701 ammeter, voltmeter E42701, E42701 kiloampermetr magneto system with rectifier has a measuring mechanism with vnutriramochnym magnet, drawing on the cores or braces and the rectifier in the measuring circuit.
They are used for the measurement of sinusoidal alternating current or voltage with a frequency of 30 Hz to 20,000 Hz.
The combination mechanism of magnetoelectric devices E42701 ammeter, voltmeter E42701, E42701 kiloampermetr the rectifier can measure the effective value of sinusoidal current or voltage, for use in circuits with undistorted sinusoidal current form.
The applied magnetic system is practically not affected by external magnetic fields, so the devices do not need additional protection when installed in a panel (the panel).
The device E42701 ammeter, voltmeter E42701, E42701 kiloampermetr performed with a square front panels and square or round body.
According to the degree of protection IP50 housing meet or IP54, protection of current-carrying rods - IP00.
Devices E42701 ammeter, voltmeter E42701, E42701 kiloampermetr electromagnetic system can measure the AC current and voltage directly to the electrical circuits.
Instruments of the electromagnetic system is based on the interaction of the magnetic field measured current (current flowing through the coil) with one or more cores of magnetic material.
By its design, produced to date equipment E42701 ammeter, voltmeter E42701, E42701 kiloampermetr electromagnetic systems have two types of measurement mechanisms:
- With a flat coil and a movable core of magnetic material, are drawn into the gap planar coil at a current is passed;
- With a circular coil with two cores inside the coil: fixed and moving (one or two), which are measured by passing a current through the coil and magnetized by the same sign repel each other, thus the arrow mounted on axis with the movable core is rejected.
Measuring instruments ammeter mechanisms E42701, E42701 voltmeter, kiloampermetr E42701 are relying on the cores from the steel and thrust.
Sedation achieved by the introduction of silicone grease to the lower thrust bearing - in devices with a circular coil and a helical spring, through which the shaft - in devices with a flat coil.
Devices E42701 ammeters, voltmeters, E42701, E42701 kiloampermetry electromagnetic system, compared with the instruments of magnetoelectric systems with rectifiers:
·               possible to measure the effective value of alternating current (voltage) in circuits with distorted waveforms sinusoidal current,
·               consume more power, less sensitive,
·               operate in a more narrow range of frequencies, especially when measuring AC voltage,
·               scale are more uneven.Readout with the normalized error in electromagnetic devices begins with approximately 20% of the nominal measuring range.
At the same time, ammeters electromagnetic system more resistant to stresses, which allows you to create devices with overload factor of 2 to 5-fold range of measurement.
In reloading equipment E42701 ammeter, voltmeter E42701, E42701 kiloampermetr error-handling in the area of the scale is not standardized.
By design, instruments for measuring alternating current can be divided into two groups:
- Devices with square faceplates and round body;
- Devices with square front panels and square buildings.
Environmental protection E42701 ammeter, voltmeter E42701, E42701 kiloampermetr - IP50 or IP54, protection class current-carrying rods - IP00.

While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.

All text and graphic information on the site is informative.
