DatasheetDWR pressure monitors are particularly suitable as pressure monitors or pressure limiters for fuel gases according to DVGW Code of Practice G 260 and liquid fuels such as fuel oil, as well as for steam systems according to TRD 604 and hot water systems according to DIN EN 12828, DIN EN 12952-11 and DIN EN 12953-9.
The DWR is used for monitoring maximum and minimum pressures. This pressure monitor features a special design and has been tested for 2 million switching cycles. TÜV and DVGW approvals are available. It is equipped with a robust housing made of seawater-resistant die-cast aluminum. The switching differential is adjustable on DWR-203 models.
Features and Benefits
- The DWR series is calibrated for rising pressure. This means that the adjustable switching pressure indicated on the scale corresponds to the switching point at rising pressure.
- The reset point is lower by the amount of the switching differential.
- On the -203 version, the switching differential is adjustable. The basic calibration remains unchanged.
- Burst pressure for all models ≥ 100 bar, verified by TÜV testing.
- Special sensor design tested for 2 million switching cycles.
- Suitable for maximum and minimum pressure monitoring.
