Vibration acceleration sensors with voltage output DVA252.XXX

Vibration acceleration sensors with voltage output DVA252.XXX

Designed for measurement of the root-mean square value (RMS) of vibration acceleration in diagnostics systems;

The sensors in the triangular case are very convenient for use in cavities and places where the cable entry from the top does not allow installation;

For installation on the sensor unit DVA252.214, a standard stud M6x1 (M8x1/M10x1/M12x1) is used; upon request, the stud can be delivered with any thread including the inch thread;

DVA252.214 allows using the cable assemblies with MIL connector from imported converters;

Output signal type - voltage (2-wire), IEPE (ICP® compatible)
