The ps/ks/j/c sensor measures structure-borne vibration in machine parts. It shows no resonance behaviour in the range of usual machine frequencies as there is no moveable mass.

Impedance is converted by electronics integrated in the housing.
The sensor is mounted on a flat surface of the machine part to be monitored using two screws.

The sensitive element contains a special sandwich of several piezo-ceramic layers, which is imbedded and hermetically sealed in the sensor body.

Measurements (B x H x D)	(34 x 24 x 23.5) mm
Sensitivity	ca. 5 nC/N
Frequency range	0.1 - 250 kHz
Connection	Miniature round plug connector RSMED3
Mountings	2 x M6x30, pan head screw with hexagon socket
	(Optional cable and connector plug as required by customer)

Connector Requirements

PIN	connection
1	+UB = 5 ... 15 V
3	Resistor R = 1 kOhm against GND (-UB = 0 V)
	Signal via R to GND

Assembly Guidelines

A = locked torque ca. 120 Ncm
B = M6 x 30

Application

The sensor ps/ks/j/c is designed for the measurement of structure-borne vibration in machine parts where the following characteristics are important:

- easy assembly
- high signal level
- no moveable mass
- signal amplitude is not dependent upon frequency range.
