It is used to measure the temperature of air-conditioning water system and refrigerant. The thin-film platinum resistance (PT1000) with good stability and high reliability produced by our company is adopted as the sensing element. 4-20MA transmitter two core wire output, IP67 protection level, with M20 cable/conduit can be inserted into the hole. There are a variety of probe lengths and housings to choose from. In order to facilitate on-site installation and protect the sensing element and transmitter from being corroded by the measured liquid, it should be used in conjunction with the corresponding bushing.
