Description

The WIKA DE compact differential pressure switch (Ex d) 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, 15 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 metering system, the DE differential pressure switch is extremely robust and provides optimum operating characteristics and maximum measurement performance with a repeatability of less than 1% of 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.

Rugged switch housing in aluminium alloy or 316L stainless steel, IP66, NEMA 4X

Repeatability: ≤ 1 % of the range

 

Areas of application, applications DE

  • filter and level control
  • differential pressure and process control
  • for gaseous, liquid and aggressive media, also in aggressive environments
  • safety critical applications in general process instrumentation, in particular in the chemical and petrochemical industries, oil and gas, power generation, incl. nuclear power plants, water/wastewater industry, mining
