Technical data of ST710-PWHVR.126
Input
E1:
External potential-free switching contact
Measuring input
F1:
Resistance thermometer Pt100-3L
Measuring range:
-200°C...350°C
Measuring accuracy: 0.5K +/- 0.5 % of scale range, without sensor
Operating range in case of temperature display like measuring range of the sensor, otherwise
