Product description
integrated digital multi-channel temperature transmitter is a micro telecontrol device designed for data acquisition and control in the presence of many thermal resistors. The bridge circuit measurement technology unique to our company in the design, with no temperature drift, no lead resistance, strong anti-interference ability, the advantages of bridge circuit and measurement circuit complete isolation etc.. It is made of aluminium alloy waterproof box, with metal isolation net, anti - radio interference and corrosion prevention. The temperature probe is designed with stainless steel probe, and the circular explosion-proof header is strong, corrosion resistant, durable, anti-interference, and has a large range of humidity.
