The PT100 is a high-precision, industrial-grade temperature transducer with a 4-20mA output, wide measuring range (-50~200°C), and robust protection features, ideal for automation and process control.
Wide range for measurements from -50~+200℃! power reverse polarity protection and overload protection! Standard 4-20mA output for RTU, PLC and acquisition equipments!
The PT100-x series Temperature transducer is thermal resistance type, output 4~20mA, 2 wired output professional transducer. This Transducer with the highly reverse connect protection.
When the transducer has not connect to the sensor, the output current ≤3.6mA, when the sensor disconnect to the transducer during working, also will output ≤3.6mA; when the sensor’s “+” contact disconnect to transducer, the output currect≤ 25±2mA.
