Overview
The Big Chief 182141 is a 20W 120V RTD resistance temperature detector designed for reliable, accurate temperature measurement in industrial and commercial applications. Resistance Temperature Detectors (RTDs) are temperature sensing devices consisting of a wire coil or deposited film of pure metal, and the element’s resistance increases with temperature in a known and repeatable manner. This unit provides stable, long-term temperature monitoring suitable for manufacturing equipment, HVAC systems, process control, and electrical thermal management.
