S120E, Proximity sensor
Description
Proximity sensor in a cylindrical housing for non-contact measurement of displacement (range 0…5.0 mm), vibration displacement and rotor bow (range 50…1000 µm), with an electronic unit built into the sensor housing. Output type: 4…20 mA DC, 3-wire connection. Operating temperature range from −40 to +150 °C.
Used in vibration monitoring channels of supports together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.
Key features:
- cylindrical housing M16*1
- extended temperature range
- 3-wire connection scheme

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