NAI’s Durapot PT are a series of Hazardous Environment Potentiometers. They are immune to electrical noise and are hardened for use in hostile environments, including explosion-proof, radiation resistant and submersible. The housings are finished with an epoxy coating that is weather and corrosion resistant, and specifically designed to withstand hydrogen sulfide, methane, chlorine and salt. Durapot PT potentiometers are capable of transmitting 4-20mA position data over a 3-wire cable over distances of up to several miles.
