Vibration velocity sensors with current output DVA141.XXX

Vibration velocity sensors with current output DVA141.XXX

Designed to measure the root mean square (RMS) value of vibration velocity in emergency protection systems (EPS);

Consist of a sealed housing, which are integrated microelectromechanical acceleration sensor and conversion board;

To install the sensor assembly DVA141.214 uses the standard stud M6x1 (M8x1/M10x1/M12x1); for the special order it is possible to supply the studs with any thread, including inch;

DVA141.214 allows the use of cable assemblies with MIL connector from imported converters;

Type of output signal - 4...20 mA
