Accurate down to the last µ – calibration of length measuring instruments
Wanted measuring instruments, as test instruments, fall under the risk determination of ISO 9001. As a result of increasing safety requirements, the importance of calibration in connection with this is greater. In the past, a good-bad test was often sufficient – as it also was, for example, with tapered thread gauges. By determining the actual […]
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. Malicious is described as follows in the book “Electronic pressure measurement”:“Pressures within the overpressure range will not cause […]
Flushing rings in diaphragm seal systems have several advantages
The extension of a flanged diaphragm seal system using a flushing ring brings significant advantages. Among other things, it enables easy cleaning and, in addition, on-site calibration of the measuring location.Diaphragm seal systems are used in processes with critical media. During some process steps, such as shutting down and cooling down the processes, media sticks […]
Integration of pressure sensors into the PLC
The construction of a traditional current loop for the capture of pressure sensor signals has its pitfalls – especially when not only a signal must be transmitted to the PLC, but also a local indicator has to be integrated. Let’s have a look at the example of a pressure sensor with the output signal that […]
