The Honeywell DWR06 (also referenced as FEMA DWR06) is a high-precision mechanical pressure switch designed for monitoring and limiting overpressure in systems containing hot water, steam, fuel gases, or liquid fuels. It is known for its "special construction," having been tested for up to 2 million operating cycles.

Pressure limiters "of special construction" (DBS) must fulfil additional safety requirements, i.e. breakageor leakage in the mechanical part of the sensor must lead to shutdown to the safe side. The pressurelimiter must respond as if the system pressure had already exceeded the maximum limit. The controlcircuit for the pressure limiter must also be considered from the point of view of safety, as short circuitsin the supply lines or other faults in the control current circuit can lead to dangerous conditions.

The DWR06 785-DWR06 Honeywell Pressure Sensors may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

In many aspects, safety engineered pressurelimiters offer a higher degree of safety comparedwith normal pressure switches and are thereforeespecially suitable for chemical processengineering and thermal installations in whichsafety is an especially critical factor in pressuremonitoring. Pressure switches can also be usedin Ex- zones (zone 0, 1, 2 and 20, 21, 22) and,in all cases, require an isolating amplifier.The isolating amplifier is also responsible formonitoring lines for short circuit and linebreak and therefore offers an additional safetyadvantage – even in non Ex-zones. ForEx-applications, the isolating amplifier must beinstalled outside the Ex-zone. The lines betweenthe isolating amplifier and the pressure switchare monitored for short circuit and line break.
  • Steam and Hot Water Systems:Pressure limiter for boilers, compliant with DIN EN12828 & EN12952-11
  • Fuel and Gas Monitoring:Monitors burnable gases (DVGW G 260) & liquid fuels like fuel oil
  • Industrial Pressure Control:Max/min pressure monitoring with high precision & repeatability
  • Seawater Environments:Seawater-resistant die-cast aluminum housing for maritime/coastal use

The resistor connected in series with the switching contact limits the current to a defined value with theswitch closed. In the event of short circuit in the area between the isolating amplifier and the seriesresistor, the current rises above the predetermined limit value, the relay of the isolating amplifier dropsout, the output current circuit is interrupted and thus the safe condition is achieved. In the event of a linebreak, the current flow is interrupted, the relay drops to the safe side and interrupts the output currentcircuit (safety sequence). Furthermore, the isolating amplifier is designed so that, if faults occur in theelectronics (conductor interruption, component defect etc.) and in the resulting situations, the safeshutdown condition is assured. These characteristics of the safety engineered isolating amplifier,including line break and short circuit monitoring, satisfy the requirements of DIN/VDE 0660, Part 209.

FAQs

  • What is the Honeywell DWR06?

    +
    It is a FEMA mechanical pressure switch/monitor used to monitor maximum and minimum pressure, designed for applications like hot water, steam, fuel gases, and liquid fuels.
  • What does DWR stand for?

    +
    The DWR series is calibrated for rising pressure, meaning the adjustable switching pressure on the scale corresponds to the switching point at rising pressure.
  • What is the maximum medium temperature?

    +
    It is designed for hot water/steam, with short-term permissible temperatures up to 85°C.
  • What is the bursting pressure?

    +
    The bursting pressure is ≥ 100 bar, verified by TÜV testing.
  • What should I do if the ambient temperature is below 0°C?

    +
    At ambient temperatures at or below 0°C, it is crucial to ensure that no condensation occurs in the sensor or the switching device.
