English DWR3 for overpressure monitoring of steam, hot water, burnable gases, liquid fuels.
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
Sensing element material: 1.4104 + 1.4571
Media temp.: -25...70C
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...70C
Ambient temp. limit: at temperatures below 0 °C, 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 Mechanical lock/reset: with special function possible
Fixed pressure hysteresis
Pressure adjustment range: 0,2...2,5bar
Adjustable switching differential: no
Switching differential: 0,1bar
Max. pressure: 16bar
Allowable max. gas-pressure: 10bar
Kind of pressure: overpressure, relative
