Description
The Honeywell DWR16-203 pressure switch is a compact, reliable, and durable device used in industrial systems with a maximum pressure of 25 bar (20 bar for gas). It monitors the occurrence of overpressure of steam, hot water, flammable gases, and liquid fuels.
Features
- The switch is assembled in a cast aluminum housing that is resistant to seawater composition, shock, corrosion, and exposure to low and high temperatures. Electrical contacts are protected from dust and moisture according to IP 54 standard.
- The device operates stably over a wide range of operating temperatures: -25…+70 °C (short-term exceedance up to +85 °C is permissible).
- When operating in negative ambient air temperatures (less than 0°C), condensation in the sensor and switching device should be prevented.
- The switch is connected using the DIN EN 175301 electrical connection plug.
Optional versions are available: with gold-plated contacts, and enhanced housing electrical protection up to IP65.
