The ACI RTD Immersion sensor is a single point temperature sensor that is designed for use with electronic controllers in commercial heating and cooling building management systems. They feature a ¼” diameter stainless steel probe and are manufactured using ACI’s proven double encapsulation process to eliminate the effects of moisture and to increase the response times using high quality, thermally conductive epoxy. The immersion sensors include a standard ½” NPS Male process thread.
