RELIABLE, LOW COST ON/OFF LEVEL SWITCH, Z-TRON III OFFERS COTE-SHIELD™ CIRCUITRY
With no moving parts to wear, break or fail, the economical Z-tron III level switch offers a maintenance-free alternative to electromechanical switches.The compact, one-piece unit installs through a standard 3/4-inch NPT fitting located at the desired high- or low-level position. Sensing element wetted parts are Type 316 SS or PEEK (polyether-ether-ketone) high-temperature thermoplastic, with Cote-Shield circuitry that allows the Z-tron III to ignore coatings or build-up on the sensing element, while preventing false signals from dust or tunneling. The unit can operate on 230Vac, 120Vac or 24Vdc input, with output signal provided by a DPDT relay.
