Rolling diaphragm design maintains a constant effective area to minimize friction, resulting in a minimum deadband as low as 5% of full scale
Many applications require higher deadbands, and this unit includes a separate adjustment of this when necessary
Both setpoint and deadband adjustments are protected, yet clearly visible behind a clear polycarbonate window and are fully isolated from the electrical components for additional safety
7/16" open-end wrench is the only tool required to change settings
Terminal blocks are provided for switch wiring connections and both internal and external ground screws are included
Standard housing is weatherproof to NEMA standards 1 through 4X and 13; explosion-proof to NEMA 7, Class I, Groups B, C & D; NEMA 9, Class II, Groups E, F & G. Optional construction adds drain to meet IP54
