Vibration and bearings status converter JPVL-52

The JPVL-52 module is determined for the diagnostics of vibration and roller bearing status during machine operation. It is constructed for DIN35mm mounting rail of switchboard with suitable protection against external influences activity.

Vibration and bearing states are indicated by one suitably located passive sensor - piezoelectric accelerometer. The sensor is connected by cable to the input connector of the module permanently evaluating in two frequency bands:

1) vibration effective speed (RMS) in band from 1Hz to 1000Hz, in adjustable measuring range from 0~10mm/s to 0~100mm/s

2) roller bearing surface wear by acoustic emission in band of 10~50kHz, so-called conjugated acceleration. The measurement proceeds in logarithmic units in dB, the measurement range is -10~+50dB. The initial level is set during machine operation. The value is reset to 0dB by pushing the button at the highest revolutions and then the module measures the value increase up to the basic level.
