DWAM, DWAMV, SDBAM Pressure monitors / pressure limiters


These series are particularly suitable for maximum pressure monitoring in steam and hot-water systems. The pressure switch is “of special construction”, with a self monitoring pressure sensor, built in accordance with Pressure Equipment Directive PED 2014/68/EU. It can be used as a pressure monitor or a pressure limiter for maximum pressure monitoring (systems in accordance with TRBS DIN EN12828) systems in accordance with DIN EN12952-11 and DIN EN12953-9 and is available with or without adjustment.
SIL 2 according IEC 61508-2

Technical data

Pressure connection
External thread G 1/2 (pressure gauge connection) to DIN 16 288 and internal
thread G 1/4 to ISO 228 Part 1.

Switching device
Rugged housing (200) made of seawater resistant die cast aluminium.

Materials
Pressure bellows: Material no. 1.4571
Sensor housing: Material no. 1.4104
Switch housing: GD AI Si 12
according to DIN 1725

Mounting position
Vertically upright and horizontal.

Ambient temperature at switching device
–20 to +70°C.

Medium temperature –20 to +70°C.
The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Temperatures may reach 85°C for short periods. Higher medium temperatures are possible provided the upper limit at the switching device is ensured by suitable measures (e.g. siphon).

Mounting
Directly on the pressure line (pressure gauge connection) or on a flat surface with two
4 mm Ø screws.

Calibration for maximum pressure switch The pressure monitors and safety pressure limiting devices are calibrated so that, under rising pressure, switching takes place at the defined switching pressure. The reset point under falling pressure is lower by the amount of the switching differential, or, in the case of pressure limiting devices, by the fall in pressure specified in the table. The scale value corresponds to the upper switching point.
