Media temp. -25 ... 70 oC
Media temp. limit temperatures up to 85 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 -25 ... 70 oC
Ambient temp. limit at temperatures below 0 oC, ensure that no water condensation can arise in the sensor and in the switching device
