The RT6 RTD assembly is a resistance temperature detector designed for use in hazardous locations. The RT6 is a customizable product that is model number configured and made to order. The RT6 consists of a stainless steel RTD sensor, complete with a connection head (enclosure) that may be provided with a terminal block, DIN rail, wire splice connectors, or internal transmitter. Connection extension fittings will spring load the sensor into a tapered threaded thermowell.
