DVA144.XXX vibration velocity sensors with digital output

DVA144.XXX vibration velocity sensors with digital output

Designed for measurement of the root-mean square (RMS) value of vibration velocity in emergency protection systems (EPS);

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

Sensor versions:

  • DVA144.104 - triangular case, all-in-one cable connection, 3-screw mount;

  • DVA144.132 - triangular case, cable with 2PM connector, mount on 3 screws;

  • DVA144.164 - triangular case, HIROSE connector on cable, mount for 3 screws;

  • DVA144.214 - cylindrical small-sized housing, MIL-DTL connector on the housing, mounting on a stud.   

To install the sensor assembly DVA144.214 uses the standard stud M6x1 (M8x1/M10x1/M12x1); for the special order it is possible to supply the studs with any thread, including inch;  

DVA144.214 allows the use of cable assemblies with MIL connector from imported sensors

Output signal type – RS-485 (Modbus RTU) or RS-485 (Modbus RTU) + discrete output
