pressure-switch-for-liquid-gas-dcm.png
 
For overpressure monitoring of non-aggressive liquids and gaseous media.
Kind of pressure overpressure, relative
Pressure connection internal thread G1/4, external thread G1/2
Electrical connection Plug DIN EN 175301
Protection class IP54
Housing material rugged housing of seawater resistant aluminium die casting GD Al Si 12.
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
Switch function/capacity SPDT Microswitch 250 Vac; capacity 5 A inductive, 8 A resistive
