ДПЭ22МВУ, Piezoelectric sensor
Description
Piezoelectric sensor designed for measuring instantaneous vibration acceleration in the range from 0 to 140 m/s² at temperatures from –40 to +180 °C.
The output signal is proportional to the instantaneous vibration acceleration value; interface – 1–5; 4–20 mA AC.
Used in vibration monitoring channels of supports together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.
Key features:
- External amplifier
- Extended temperature range
