Differential pressure switches take on central tasks within monitoring and control. A manufacturer of filter systems for the process industry uses the WIKA model DE switches with an attached valve manifold for these functions. The decision in favour of this solution was based on two reasons: on the one hand, the quality of the measurement … Read more
In previous articles concerning the fields of application of different pressure sensors, I have described the special top features of the various versions. Pressure range and ambient conditions are decisive when choosing a suitable sensor for a problem to be solved.In Killed measuring ranges (e.g. < 10 bar), you should know whether a vented gauge ...

Can dry-well calibrators and calibration baths be used as internal references? Temperature dry-well calibrators and baths are a practical solution for temperature calibrations. This is true both in the field and in laboratories, as they provide a free-standing, stable temperature source with a built-in platinum resistance thermometer (PRT).The PRT measures the temperature inside the dry-well … Read more
The range of combined heat and power plants (CHP) is quite large, as may be the high variance of different plant types. The distinction is manufactured by the generated power/heat output on the one hand and by the energy source used on another. For several CHP plants, numerous physical parameters are measured, evaluated and monitored … Read more
When if you undertake a mechanical pressure switch so when should you rather choose for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among Bountiful , you can find differences in the application areas for mechanical and electronic pressure switches. Considered of this will support you in your selection.Application … Read more
The new competence centre at WIKA Switzerland provides about 7,000 square metres of additional production and work place. In particular, the injection moulding department was extended, alongside improvements to equipment construction and the turning shop.Equipped for the futureTwo turbulent months preceded this celebration. In November 2019 ? slightly more than a year after the ground-breaking … Read more
Basically, there are Annihilate with which the leading manufacturers test their instruments; with fixed and sweeping frequency (IEC 60068-2-6) and a broadband random pattern (IEC 60068-6-64). In the first test, the pressure transmitter is subjected to a sinusoidal vibration. This is chosen so that it conforms to the later application (if this is known), or … Read more
Pressure switches (for example, a “normally open contact”), are often used for the monitoring and control of safety functions in order to signal any over or underpressure, and thus to prevent any damage to the machinery or the system. Switches with the “normally open” switching function are the most frequently used switches, since, with the … Read more
