Bimetal maximum current meters with a bimetal measuring system are intended for testing the thermal load of transformers, cables, electrical machines, etc. They indicate average rms current value in a setting period of 8 minutes (on request
Combined bimetal maximum current meters are provided with a built-in bimetal system and a system with a moving iron. The meters are intended for testing momentary and thermal load of transformers, cables, electrical machinery, etc. Meters
The MI 7350 can signal minimal and maximal setting limits (MIN and MAX). The meter is provided with two output relays of 600 VA switching power. Setting over or under the limits is displayed with a LED on the meter scale. DC or AC currents or voltages
Meters with a moving iron are intended for measurement of AC currents or voltages of frequencies from 15 Hz to 100 Hz. They measure rms values independently on the signal form of current or voltage
Meters with a moving coil and a rectifier are intended for measurement of AC currents or voltages in the frequency range from 40 Hz to 65 Hz (higher frequency range on request), where low meter consumption is required. The meters measure the
Owing to a special form and available colours, BN and CN meters are especially convenient for building into different control devices. The accuracy class is 1.5. The scale is not interchangeable. BN meters are used for DC currents or voltages
Meters with a moving coil are intended for measurement of direct currents or voltages. A measuring system with a core magnet is not sensitive to external electromagnetic fields and is resistant to mechanical impacts and vibrations
Pointer frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz. The accuracy class is 0.5
Power factor meters are intended for measurement of power factorb (cosϕ) in a three-phase three-wire network with a balanced load of phases or in a single phase network. The accuracy class is 1.5.
Reed frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz. Two-system reed frequency meters are intended for measurement of two frequencies in the system for synchronisation. Their class is 0.5.
TAP meters with a moving coil are intended for measurement of tap position with auxiliary supply AC voltage. The position indicator monitors transformer tap position, hoist or valve position etc. It employs a bridge system. 1-2 positions
