WIKA PSD-30 Indicating Pressure Switch

Supplier: WIKA Australia

The convenience of a self indicating pressure transmitter has been further enhanced with a switching function. The WIKA PSD-10 has a standard 4...20mA transmitter with a digital display which can have one or two switching points to activate pumps or alarms as required.


WIKA Alexander Wiegand GmbH & Co. KG has received the iF product design award for its innovative PSD-30 Electronic Pressure Switch with Digital Display.

The pressure switch, which is used in the manufacture of Machine tools to control Hydraulic and Pneumatic pressures, which operate with-in these machines, impressed the jury in a total of ten criteria; Design Quality, Degree of innovation, Selection of Materials, Functionality, Ergonomics, Safety, Branding, Universal Design, Environmental Compatibility and Visualisation of use.

The iF product design awards are presented on an annual basis to products which succeed especially well in combining functionality with convenience and aesthetics, as well as in satisfying the requirements for innovation. For decades, the iF product design awards have represented a kind of "seal of quality" for design excellence.

WIKA have manufactured Pressure measuring instruments for over 60 years and the new PSD-30 Indicating Switch represents the latest in a line of high quality instruments leading the market in quality and innovation. The 9mm high LED digital display with 14-Segments offers significant legibility improvement over previous models and leads the competition with it's simple and intuitive 3-Key operation.

The availability of two independent switching points and optional 4...20mA signal output gives this switch the versatility to satisfy the most demanding application requirements. The stainless steel case offers an ingress protection of IP67 with a robust stainless steel M12 electrical connection and all 316 Stainless steel wetted components are compatible with most process conditions.

Available pressure ranges start from vacuum right up to 600bar and are also available in absolute pressure ranges. The versatile display will display the process pressures directly in the following units: bar, psi, MPa, kPa and kg/cm2. The switch set points are adjustable between 1% and 99% of the instruments pressure range and the value can be adjusted at any time to be either NO or NC. Installation flexibility is further enhanced with the rotation of the case up to 320o and the rotation of the display by up to 330o and the digital display can be inverted by 180o to increase visibility in just about all mounting orientations. 

The main characteristic of measuring technology is the documented accuracy. As an additional bonus for the customer, each PSD-30 is accompanied by a free test report documenting the final check during manufacture. This certificate records the actual measuring accuracy and documents the set parameters of the set points.

As a renowned manufacturer of modern measurement technology, the functional aspects of product design are always of paramount importance at WIKA. With the new generation pressure switch PSD-30 we have incorporated proven technology and given users valuable new novel features making their work easier.
