Sensor curves

DANGER:
Danger to life due to electric shock!
Before opening the device:
▶ Isolate the mains voltage.
▶ Secure against unintentional reconnection.
Checking fault:
▶ Remove sensor terminals.
▶ Check the resistance at the temperature sensor cable ends
using an ohmmeter.
▶ Check the temperature at the temperature sensor with
a thermometer.
The following tables show whether the temperature and pressure
drop value correspond.
The sensor tolerance for all curves is ± 3 % at 25 °C.
