Media temp. -15 ... 60 oC Media temp. limit temperatures up to 80 oC are allowable for short periods. Higher
temperatures are possible, provided that the limit is safeguarded by
suitable measures (e.g. water tube trap, see Accessories for Pressure
Switches / Transmitters)
Ambient temperature -15 ... 60 oC Ambient temp. limit at temperatures below 0 oC, ensure that no water condensation can
arise in the sensor and in the switching device
