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;
  • DVA144.164 - triangular case, TIK-KXX connector on cable, mount for 3 screws;
  • DVA144.214 - cylindrical small-sized housing, TIK-KXX connector on the body (analogue of MIL-C-5015), mounting on a stud;
  • DVA144.714 - rectangular case, TIK-KXX connector on the body (analogue of MIL-C-5015), 1 screw mount;

To install the sensor assembly DVA144.214 uses the standard stud 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
