Output signals 4 ... 20 mA, 0 ... 20 mA, 0 ... 10 V for the transmission of process values to the control room
For measuring locations with a high differential pressure overload and/or high working pressures (static pressures), also in aggressive environments
Easy-to-read, analogue on-site display needing no external power
Special Features
High working pressure (static pressure) and high overload safety, selectable up to 40, 100, 250 or 400 bar
Hydraulic cushioning protection against rapid pressure changes
No configuration necessary due to "plug-and-play"
Differential pressure measuring ranges from 0 … 60 mbar
Individual, non-linear characteristic curves (e. g. x2 or √x for flow measurement)
Description
Even if the voltage supply is completely lost, the differential pressure can be read securely. The robust diaphragm measuring system produces a pointer rotation proportional to the pressure.
An electronic angle encoder, proven in safety-critical automotive applications, determines the position of the pointer shaft – it is a non-contact sensor and therefore completely free from wear and friction.
From this, the electrical output signal, proportional to the pressure, of 4 ... 20 mA, is produced. In addition, the electrical zero point can be set manually.
These differential pressure measuring instruments are made of highly corrosion-resistant stainless steel. A high overload safety is achieved by the all-metal construction and the close-fitting design of the diaphragm pressure element.
The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments
Solutions for pressure, temperature, force and level measurement, flow measurement, calibration and SF6 gas solutions from WIKA are components integrated in the business processes of our customers.
