DVA244.XXX vibration acceleration sensors with digital output

DVA244.XXX vibration acceleration sensors with digital output

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

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

Sensor versions:

  • DVA244.104 - triangular case, all-in-one cable connection, 3-screw mount;

  • DVA244.132 - triangular case, cable with 2PM connector, mount on 3 screws;

  • DVA244.164 - triangular case, HIROSE connector on cable, mount for 3 screws;

  • DVA244.214 - cylindrical small-sized housing, MIL-DTL connector on the housing, mounting on a stud.   

To install the sensor assembly DVA244.214 uses the standard stud M6x1 (M8x1/M10x1/M12x1); for the special order it is possible to supply the studs with any thread, including inch;  

DVA244.214 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
