DatasheetDWR pressure switches are particularly suitable as pressure monitors or pressure limiters for combustible gases (DVGW worksheet G 260) and liquid fuels (e.g., heating oil), as well as for steam systems according to TRD 604 and hot water systems according to DIN EN12828, systems according to DIN EN12952-11, and DIN EN12953-9. The DWR is used to monitor maximum and minimum pressures. This pressure switch is a “special design” and has been tested with 2 million switching cycles. TÜV and DVGW tests have been carried out. It features a robust housing made of seawater-resistant aluminum die-cast. The switching differential is adjustable for the DWR-203 types.
Features & Benefits:
- The DWR series is calibrated for rising pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at increasing pressure. The reset point is lower by the amount of the switching differential. For the … -203 model, the switching differential is adjustable. The base calibration is retained. Burst pressure for all types ≥ 100 bar, as proven by TÜV testing.
- “Special design” sensor tested for 2 million cycles.
- For monitoring maximum and minimum pressure.
