DVA274.XXX vibration acceleration sensors with digital output

DVA274.XXX vibration acceleration sensors with digital output

Designed to measure the root mean square (RMS) value of vibration velocity on two axes simultaneously, vector addition of these values and the issuance of the resulting amount in emergency protection systems (EPS);

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

Sensor versions:

  • DVA274.104 - triangular case, all-in-one cable connection, 3-screw mount;
  • DVA274.164 - triangular case, TIK-KXX connector on cable, mount for 3 screws;
  • DVA274.214 - cylindrical small-sized housing, TIK-KXX connector on the body (analogue of MIL-C-5015), mounting on a stud;
  • DVA274.714 - rectangular case, TIK-KXX connector on the body (analogue of MIL-C-5015), 1 screw mount;

To install the sensor assembly DVA274.214 uses the standard stud M8 / M10 / M12; for the special order it is possible to supply the studs with any thread, including inch;

DVA274.214 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
