The 651 RF Admittance Single Point Level Switch is a level control which

uses dielectric constant and conductivity to detect the level of liquids,

slurries, granulars, and solids. When used with any of the RF Probes,

it will provide accurate switching for level processes.

The control features a fail-safe switch which reverses the operation of

the relay. An LED inside the housing lights when the process is touching

the probe. A sensitivity adjustment inside the control allows the user to

increase or decrease sensitivity as needed. Optional time delay feature

will delay switching on or off from 0 to 60 seconds.
