Monitoring Burners and Boilers
For installations according to TRBS and DIN 12828.
These are steam and hotwater boilers for commercial industrial applications. The devices can also be employed in monitoring unfired pressure vessels (EN 764-7).
DWR - Pressure monitors and limiters
Expecially suitable as a pressure monitor or pressure limiter for fuel gases (DVGW Worksheet G260) and liquid fuels (e.g. fuel oil), as well as for steam systems according to TRD 604 and hot-water systems to DIN EN 14697. The DWR-series is used to monitor maximum and minimum pressures.
These pressure switches are "of special construction" and have been tested with 2 million operating cycles. TÜV and DVGW test exist.
The pressure limiters are equipped with a reclosing lockout for the mechanical interlocking of the switch-off state. If the switching point set on the pressure limiter is reached, the limiter switches off, the switch-off state is retained even if the pressure changes again. Switching back is possible only by manual actuation of the reset button. The pressure at the sensor must have lowered so that unlocking is possible (for maximum pressure limiters) or raised (for minimum pressure limiters).

SDBAM/DWAM - Pressure monitor and Pressure limiter
These series are particularly suitable for maximum pressure monitoring in steam and hot-water systems. They are of "special construction", with a self-monitoring pressure sensor, built in accordane with Pressure Equipment Directive 2014/68/EU. They can be used as a pressure monitor or a pressure limiter for maximum pressure monitoring (systems in accordance with TRBS DIN EN 12828), systems in accordance with DIN EN 12952-11 and DIN EN 12953-9 and are available with or without adjustment.
Maximum pressure monitor
Maximum pressure monitor of 'special construction' with selfmonitoring sensor for steam and hot water
Maximum pressure limiter
Maximum pressure limiter of 'special construction' with selfmonitoring sensor and internal relock. For steam and hot water.
DGM - Pressure monitors for fuel gases
These pressure monitors are DVGW tested to DIN EN 1854 and are suitable for all gases in accordance with DVGW Worksheet G260 and for air.
