PNF Point Level Switch

It is is a non-contacting, non-invasive point level switch for high or low level indication. Highly reliable and rugged, it provides cost-effective on-off control of circuits. It consists of two components: an energy source in a steel-jacketed housing and the detector/electronics, and operates on the principle of gamma ray attenuation.
