ИП34Ex, Converter
Description
Converter ИП34Ех for measurement of displacement and relative vibration displacement in combination with Eddy-current sensor ДВТ10Ех; ДВТ20Ех at temperatures from -40 to +70 °C. The 1...5; 4…20 mA DC output signal is proportional to the displacement of the target surface relative to the sensor.
Used together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.
Key features:
- explosionproof version 1ExibIIBT3 GbX
- Type of explosion protection — intrinsically safe electrical circuit "i"
- Requirement to be connected into intrinsically safe electrical circuits
- Installation in special metal converter boxes

Applications
Measurement of the displacement; rotor vibration displacement; rotor bow (eccentricity); rotor axial shift with Eddy-current sensor ДВТ10Ex; ДВТ20Ex in steam, gas and hydraulic turbine units, turbocompressors, centrifugal pumps and other machines during their operation.
The sensor can be used both independently and as part of the measurement channels of the plant's SCADA systems.
