The Danfoss 013G-8565 Wall Mount Sensor & Dial RA2000 is an effective temperature sensor for controlling the temperatures in heating, ventilating, and air conditioning systems. Another feature of this sensor is it has a capillary tube of 16 feet in length which means that it can be placed in the required area and can read the temperature without proximity. https://www.partshnc.com/wallmntsnsrdail-16cap-ra2000
