Pressure Switches & Sensors

Ex-DWR Pressure Monitors/Pressure Limiters

Especially suitable as a pressure monitor or limiter for fuel gases(DVGW Worksheet G 260) and liquid fuels & also for steam systems according to TRD 604 and hot water systems to DIN EN12828, systems in accordance to DIN EN12952-11 and DIN EN12953-9.

Overview

Ex-DWR Pressure Monitors/Pressure Limiters are especially suitable as a pressure monitor or pressure limiter for fuel gases (DVGW Worksheet G 260) and liquid fuels (e.g. fuel oil), as well as for steam systems according to TRD 604 and hot water systems to DIN EN12828, systems in accordance to DIN EN12952-11 and DIN EN12953-9. The DWR is used to monitor maximum and minimum pressures. This pressure switch is "of special construction" and has been tested with 2 million operating cycles. TÜV and DVGW tests exists.It comes with robust hosuing made of seawaterresistant die cast aluminium.

Features & Benefits:
  • he Ex-DWR series is calibrated for rising pressure. This means that the adjustable switching pressureon the scale corresponds to the switching point at rising pressure. The reset point is lower bythe amount of the switching differential.
  • Sensor is "Of special construction" by testing with 2 million cycles.
  • For maximum and minimum pressure monitoring
  • Bursting pressure for all types ≥ 100 bar, verified by TÜV test.
Certifications:
  • TV.DWFS (SDBFS).17-281 according VdTUEV Memorandum Pressure 100, Issue 03.2017 and DIN EN 12952-11 and DIN EN 12953-9:2007
  • ID 0000035004 according DIN EN 764-7:2002 and DIN EN 13611:2008
