Training at WIKA Switzerland really is a great thing
Ten percent of all those who work at WIKA Switzerland are in training. Their designation is “apprentice”. Currently, 30 young people are growing into nine different professions. For the Hitzkirch subsidiary, they are the future of the industry – the corporate commitment is correspondingly high.Training at WIKA Switzerland really is a great thing. The individual […]
Pressure and temperature measurement at extremely low ambient temperatures
Standard pressure gauges and thermometers generally cope with ambient temperatures right down to -40 �C. But what should be the top features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using the WIKA POLARgauge� as an example. This product family has been designed […]
RoHS-compliant does not equal lead-free
In practice, RoHS-compliant is often equated with “lead-free”. However, เพรสเชอร์เกิจ is a widespread mistake. The RoHS directive 2002/95/EC aims to minimize the use of hazardous substances (including, among others, lead), but it does not completely exclude a small percentage. One of the great obstacles in implementing the directive was the switchover to lead-free solder, because […]
Analogue output signals of pressure sensors 2: DC 0 … 10 V, DC 1 … 5 V, DC 1 … 10 V
Apart from pressure gauge described in the article “Analogue output signals of pressure sensors 1”, the voltage signals 0 … 10 V, 1 … 5 V and 1 … 10 V are used in industrial automation for the transmission of measured values.As with the current signals, their advantage is the ease of use and the […]
EAC – The certification system of the Eurasian Economic Union in overview
“ … with EAC, please.” This statement is often added when a product is to be exported to Russia or another CIS (Commonwealth of Independent States) country – be it as a single device or installed in a machine. But what exactly is EAC and when do you need it?This blog post discusses the change […]
Monitoring the level in liquid gas tanks with a Cryo Gauge
In the past, monitoring the filling level in liquid gas tanks using differential pressure has always been a challenge. This is because the manufacturers of tank equipment had to construct their own measuring systems in order to record the liquid level and the operating pressure of the respective gases. With the innovative differential pressure gauges […]
Integrated M12 Y-connector vs. external T-piece: Advantages/ comparison in CANopen pressure sensors
The main reason for using a pressure sensor with CANopen interface compared to customary analogue sensors is the low degree of wiring required and the high reliability of signal transmission. The data and power cables of the CAN bus are combined in a single shielded CAN cable and passed on from one bus user to […]
When to use electronic pressure switches and pressure sensors
For a very long time, mechanical pressure switches were state-of-the-art for control in manufacturing processes. Modern pressure sensors seem to be the answer to the demand for data collection and control, by providing continuous data output about the process pressure.However, why have electronic pressure switches become so popular, even though an analogue output signal from […]
Unified colour codes and cable assignment for cable wires of pressure sensors
Why are there no unified colour codes for cable wires of the pressure sensors? This question is entirely justified, because unified wire colours would simplify everything. Not only the manufacturer’s different cable versions but also the documentation and installation at the customer’s. But unfortunately, as already suggested by the question, there are no unified colour […]
Ice cold – Electrical thermometers in low ambient temperatures
Medium temperatures of -60 °C don’t even make the designers of electrical thermometers shrug their shoulders – but when one speaks of ambient temperatures of -60 °C, then one often hears a sharp intake of (cold) breath.It quickly becomes clear that one cannot readily use standard instruments here. Global warming on the one hand, requests […]
