Temperature and Humidity Sensor

Product Description

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.
