Features & Benefits:

  • Offers two set points with individual alert and alarm relays

  • 4 to 20 mA output signal for vibration monitoring

  • Analogue, 100 mV/g output signal for fault diagnostics

  • Utilizes built-in or remote vibration sensor

  • Choice of AC or DC power

  • Adjustable time delay

  • Accepts 4 to 20 mA calibrator input signal for accurate threshold value set-up

  • Optional adaptors for retrofitting existing switch installations

This precision electronic vibration switch is AC or DC powered, utilizes an on-board or remote accelerometer, provides two relay or triac outputs, generates a 4 to 20 mA vibration output signal, and offers an analogue vibration signal for FFT analysis and fault diagnostics.

Electronic switches require power to operate and utilize an input signal that is provided by an electronic vibration sensor, or accelerometer. This sensor may be built into the switch enclosure, or remotely located. A remote sensor is advantageous when the vibration switch enclosure will not fit within the installation location, or if the temperature at the installation location exceeds the capability of the switch's electronic components. The amplitude of the electrical signal generated by the sensor is proportional to the experienced vibration. Circuitry within the switch compares this signal amplitude against a predetermined threshold value.
