Features
● High quality, good anti-interference, high cost performance
● Large round head installation
● Temperature range : -50 ... 400°C
● 4 ... 20 mA
● ZERO / SPAN adjustable
● Polarity protection ; Over-voltage ; Short-circuit
Introduction
● Linearised temperature measurement with Pt100 sensor
● To avoid temperature signal attenuation during long-distance transmission, it converts Pt100 into standard analog current output DC 4 ... 20 mA (2-wire)
● In this way, a stable and accurate figure can be collected and shown on the display of terminal instrument. The instrument includes PLC, digital display, industrial computer, etc
