Pressure Switches & Sensors

DWR Pressure Limiters

Especially suitable as a pressure limiter for fuel gases (DVGW work sheet G 260) and liquid fuels, as well as for steam systems according to TRBS and hot water systems to DIN EN12828, systems in accordance to DIN EN12952-11 and DIN EN12953-9.

Overview

DWR Pressure limiters are especially suitable as a pressure limiter for fuel gases (DVGW work sheet G 260) and liquid fuels (e.g. fuel oil), as well as for steam systems according to TRBS and hot water systems to DIN EN12828, systems in accordance to DIN EN12952-11 and DIN EN12953-9. The DWR-205/-206 is used to limit maximum and minimum pressures and has an internal interlock.Important: When selecting the limiter, it is necessary to decide whether the device is tobe used for maximum or minimum pressure monitoring. The direction of action cannot bereversed at the pressure limiter.It comes with a rugged housing made of seawater resistant die cast aluminium

Features & Benefits:
  • The DWR-205 series is calibrated for risingpressure. This means that the adjustableswitching pressure on the scale corresponds tothe switching point at rising pressure. The resetpoint is lower by the amount of the switchingdifferential. (See also page 23, 2. Calibration atupper switching point). The DWR-206 series iscalibrated for falling pressure.
  • This means thatthe adjustable switching pressure on the scalecorresponds to the switching point at fallingpressure. The reset point is higher by the amount of the switching differential.
  • Bursting pressure for all types ≥ 100 bar,verified by TÜV test.
  • Sensor is "Of special construction" by testing with 2 million cycles.
