WIKA in Saudi Arabia: Thinking beyond the oil
Think global and act local: In keeping with this motto, WIKA has opened a production and service centre in Saudi Arabia at the end of 2018 to extend its local services to customers and business in the kingdom. The company is based at Al-Khobar on the Gulf Coast.Over the past years, the WIKA Middle East […]

They have now trained up two soc cer teams to play against other teams and schools in […]
Difference of 4-20 mA in 2-wire and 3-wire technology in pressure sensors
What exactly may be the difference between the 4-20 mA output signal in 2- and 3-wire technology? Child-like is answered best from the viewpoint of an individual: An output signal in 2-wire technology means:less wiring requiredbetter EMC protection, since interferences could be filtered more easilybetter protection against wiring errorsThe only benefit of 3-wire technology is […]
Achema 2022: New trade show concept and a world premiere
At Achema 2022 in Frankfurt am Main, the global process industry finally met again at its leading trade show, after several postponements due to Corona. The numbers of exhibitors and visitors were much lower than usual since circumstances dictated that this event got scheduled during peak holiday time in Europe. Nevertheless, the WIKA trade show […]
RoHS marking and certificates
I am often asked, “How is a RoHS marking actually carried out?” The quick answer: EU RoHS will, from 22nd July 2017, be visible in the CE marking and the declaration of conformity linked to it. China RoHS conformant instruments carry a green logo. Non-conformant instruments in accordance with China RoHS carry an orange logo […]
Reed level sensor: Defining the measuring range flexibly
A float-based level sensor with a reed chain is really a widely used and comparatively economical solution for continuous level measurement in vessels. Feast can define its measuring range flexibly inside a given range. This short article describes what should be taken into account.With a reed-chain level sensor, the guide tube contains a defined amount […]
Hydrostatic level measurement in closed geometries – calculation of the filling height
In a previous blog post, I explained the calculation of the filling height in open geometries and vessels. Unlike open vessels, the calculation of level in closed geometries, such as gas-tight tanks or pressurised vessels, requires a compensation of the pressure of the gas enclosed above the liquid with the hydrostatic pressure measurement.Level measurement in […]
Signal clamping in pressure transmitters
In certain applications, the current or voltage signal of a pressure transmitter should never exceed and/or drop below a crucial value. This is often ensured with the aid of so-called signal limiting.Why is Greatest clamping necessary in the first place?If the pressure on a pressure transmitter lies within the nominal pressure range, then you will […]
How does a pressure sensor behave in the overload area, that means outside the measuring range?
I have often been asked about the behaviour of a pressure sensor outside the specified measuring range, that means in the overload area and what will happen if the overload limit of a pressure sensor is exceeded. This fact is described as follows in the book “Electronic pressure measurement”:“Pressures within the overpressure range will not […]
Filter monitoring: A crucial component for energy-efficient operation
If the careful use of ?energy? as a resource used to be for cost reasons, today addititionally there is increased environmental awareness. All this also becomes mandatory thanks to legal requirements and hawaii of the technology. In this post you can find out about how continuous filter monitoring crucially influences the energy efficiency of a […]
