DWR (Pressure Monitor)
DWR ... 205 (Maximum - Pressure Limiter)
DWR ... 206 (Minimum - Pressure Limiter)

Special features

“Of special construction” according to pressure standard “Druck 100/1”
Welded sensor completely made of stainless steel
Can be used for maximum pressure and minimum pressure monitoring as monitor and limiting device with internal or external interlock.
Available in EEx-d orEEx-i version (see also DBS-series).
Medium and ambient temperature –25 to +70 °C (for Ex-version –15 to +60 °C).

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).

Smart Temp - Electronic Thermostat / Transmitter

Honeywell FEMA's TST and TST...R series thermostats require adjustment (configuration and parameterization) in only two modes (the basic mode and the expert mode) and are suitable for the precision-adjustment and monitoring of medium temperatures in the fields of plant construction, fluidics, process technology, and pneumatics, as well as in the monitoring and control of furnaces, heating units, and process temperatures, as well as for applications in the field of frost protection.

Smart Temp - TST - (Electronic Thermostat and Transmitter)

These thermostats provide sufficient accuracy (0.5% of the final value) for measurement monitoring in many laboratory applications. Models with built-on sensors for a temperature range of -50...+200 °C and models with an ex-ternal sensor for a temperature range of -50...+400 °C are available. Customized Pt 1000 precision class-A sensors can also be employed in the aforementioned
temperature ranges.

K - Solenoid valves for gas, liquid gas and liquid fuels

Suitable for all gases according DVGW-data sheet G 260, for liquid phase (up to DN 25) and for fuel oil.
Minimum differential pressure is not necessary.
The solenoid valves are also available with a flame-proof enclosed solenoid system.
EC-Type-examination Certificate Number: PTB 04 ATEX 1026.
Operating mode: normally closed.
