Accuracy
(Pt100, -50...200 °C) <= 0,2 K
(Pt100, -58...392 °F) <= 0,4 °F
Field of application
The transmitter is designed for the transformation of an RTD Pt100 sensor signal in a fixed measuring range. The standardized output signal used for process measurement is a 4 to 20 mA signal. This means fast, easy and cost-saving temperature measuring as well as reliable and precise measured values for for a wide range of industry applications. Installation is realized on DIN rail according to IEC 60715 (housing width: 22.5 mm).
Fixed range temperature transmitter for converting a Pt100 input signal into a scalable 4 to 20 mA analog output signal
Input: Resistance thermometer (RTD) Pt100
For DIN rail mounting
