Maximum pressure limiter with selfmonitoring sensor and internal interlock for steam and hot water. Microswith not positive opening. Contacts: silver alloy. Explosion protection code: Ex II 1/2G Ex ia IIC T6 Ga/Gb, Ex II 1/2D Ex ia IIIC T80 oC
Intrinsically Safety: The equipment employed in explosion relevant areas are components of inherently safe electrical circuits. An electrical circuit is inherently safe if the amount of energy it contains is so small that no spark or other thermal effect can arise. This reliably prevents the ignition of explosive gas mixtures in the proximity of this equipment. In the context of this directive, pressure switches and thermostats containing no switching components with energy storage effects are referred to as "simple electrical equipment."
Kind of pressure overpressure, relative
Pressure connection internal thread G1/4, external thread G1/2
Electrical connection terminal connection M16x1,5
Protection class IP65
Housing material rugged housing of seawater resistant aluminium die casting GD Al Si 12. Aluminium housing coated with resistant plastic
Sensing element material 1.4104 + 1.4571
Media temp. -20 ... 60 oC
Media temp. limit 60 oC. 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 -20 ... 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
Switch function/capacity Power supply circuit: Ui = 14 V DC Ri = 1500 Ohm Ci = 1 nF Li = 100 Mikro-H
