The vibration switch CVS 100 allows a cost effective realization of vibration monitoring for stand-alone machines and auxiliary aggregates (e.g. fans, pumps, centrifuges, mills, gears, etc.), on whose functions important Installations or processes are depending. It allows, among other things, the monitoring according to DIN ISO 10816 Part 1-7. Utilized for this are the Vibrations of main machine parts (pillow blocks, foundations,

casings) converted by rugged acceleration pick ups in electrical signals and processed and assessed with integrated electronics.

The signal- and processing electronics is fitted together with the acceleration sensor into aluminum housing, fitted directly onto the machine to be observed. One or two adjustable level detectors with selectable response delay is allowing the signalization of „Alarm “and „Danger “via appropriate dry contacts of assigned relays.

FUNCTIONAL DESCRIPTION

The signal of the internal accelerometer is led via an amplifier and integrator as well as a

bandpass filter and rectifier for further processing. The measuring ranges are selectable by

dip switch. The analogue signal available here is calibrated as the effective value of the

vibration velocity (mm/s effective). The signal acts on two adjustable level detectors and is

available as an analogue value in the form of 4...+20mA. A raw signal of 100mV/g is also

available on the terminal strip. The changeover contacts of the associated relay enable the

setting up of signal circuits (Alarm / Danger).
