NIVELCO NIVOSWITCH R-400 Series User Manual

Thank you for choosing a NIVELCO instrument
We are sure that you will be satisfied with it throughout its use
1. OPERATION
The NIVOSWITCH is a mechanical resonance system; excited, and kept in resonance by an electronic circuitry.
The process medium, when reaching the tines of vibration fork, modifies the vibration. This variation is sensed by an
electronic circuit, which, on the elapse of the delay time, actuates the output circuit. The unit has SPDT relay output.
A virtual DPDT relay feature is achieved through an optional second relay.
