- no power supply required for switching electrical loads
- 1 set point, SPDT, high switching power up to 250 V AC, 10 A
- setting from 0.3 … 2.5 mbar to 0.7 … 16 mbar at high working pressure and high static pressure up to 300 mbar
The DW03UN differential pressure switch for low setting ranges from WIKA is used for pressure measurement of gaseous and liquid media.
These high quality differential pressure switches have been developed specifically for safety critical applications. High product quality and ISO 9001 manufacturing ensure reliable control of your plant. In production, the switches are tracked every step of the way by quality assurance software and then 100% tested.
To ensure the most flexible operation, the differential pressure switches are equipped with micro-switches that allow direct switching of electrical loads up to 250 V, 20 A.
For lower switching power ratings, for example for PLC applications, argon-filled micro switches with gold-plated contacts can be chosen as an option.
All wetted materials are stainless steel as standard. For applications with special requirements in wet areas, a version with Monel® is available.
Using a diaphragm measuring system, the DW differential pressure switch model is extremely robust and provides optimum operating characteristics and highest measurement performance with a repeatability of less than 1% of the span.
The process connection with a centre distance of 54 mm of the lower bracket allows easy and comfortable installation of a standard valve manifold. Ex ia intrinsic safety available. Rugged 316L stainless steel switch housing, IP66, NEMA 4X
Areas of application, applications DW03UN
