Ex-d vs Ex-i … why should I care?
I was a freshly graduated mechanical engineer when I started my career in the maintenance department of a petrochemical plant. One of the many jobs that we needed to attend to was checking the status of the pressure transmitters that were installed on our production lines, making a list of the points that needed attention […]
3 1/2- vs. 4-digit digital indicator ? What is a 1/2 digit?
Besides 3- and 4-digit digital indicators, additionally, there are 3 1/2-digit indicators available for sale. But what is a 1/2 digit?A complete digit can indicate all numbers from ?0? to ?9?. A 1/2 digit, in contrast, can only just display a ?1?, lots ?2? or higher isn’t possible. With a 3 1/2-digit digital indicator, the […]

The material will support the business?s internal and external communication.In the video studio, several cameras with high res (4K) are available […]
Template for the creation of a proof of intrinsic safety for ATEX certified pressure sensors
In my last article I introduced you to how the “basic” proof of intrinsic safety can be provided for instruments and pressure sensors approved to ATEX in Europe. Each installer or operator must ensure that the employees in the plant are not endangered and certainly not injured. Therefore, when using intrinsically safe protection methods, it […]
Atmosphere of giving at Mensor
Mensor Cares is a group of Mensor employees who have confidence in the spirit of working together and help others in need. As a way to support other non-profits, an own non-profit organisation was financed and formed through payroll deductions, Susan Fisher reports:Early 2015 a discussion started about how our contributions could be used. Which […]
Temperature switches in machine building: Which type suits?
Temperature switches are employed in machine building and other industrial applications for limiting temperature. They monitor the temperature and react at a predefined point. To protect from overheating they either switch the gear or machine off or activate a fan for cooling. Based on the task accessible, temperature switches operate as either normally-closed or normally-open […]
Safe filter monitoring with differential pressure gauges
Hurry is a core task of differential pressure gauges ? Unleashed increases as soon as the filter becomes clogged. The measuring instruments thus signal when the filter has to be cleaned or replaced. The efficiency of this type of solution could be illustrated by the example of WIKA pressure gauges of the DELTA-line series in […]
Calibration of ultra-high pressures over the entire measuring range
The calibration of ultra-high pressures is a challenge. This is because conventional test instruments are only designed for pressures up to 1,000 bar. In many applications, however, sensors work with several times this value, for example in the automotive industry. If you want to calibrate such devices over the entire measuring range, WIKA has the […]
Level monitoring in milk tanks using a process transmitter
Level monitoring using a process transmitter with a flush diaphragm is an option for applications in the food industry. It is highly accurate and at the same time suitable for aseptic tanks. A manufacturer of dairy products (milk, cream and yoghurt), for example, uses the UPT-21 process transmitter in Hygienic Design from WIKA to control […]
Turning hydrogen into kilometres
Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly along with powerful. The growing demand for these zero-emission drives is currently focused first of all on commercial vehicles. In Switzerland for instance, the ? Break ?, in collaboration with a significant automobile manufacturer, aims to introduce 1,600 hydrogen-powered trucks to its roads by 2025. […]
