Z-Tron IV
The Z-Tron IV level switch is one of our most popular on/off level switches offering an effective, low-cost material level detection in a wide variety of applications. It is widely used as an alternative to electromechanical level switches.

This level switch is unaffected by sticky coatings and impervious to corrosive liquids.

The Cote-Shield circuitry allows the Z-tron IV to ignore coatings or build up on the sensing element. No false signals from tunneling or dust will occour when using the Z-tron IV. 

This level switch is a one-piece unit and is easily installed through a single 3/4-inch vessel opening.

Calibration is quick and simple and the Z-Tron IV does not require routine maintenance, cleaning or replacement of worn parts.
