Certification describes the common practice with that your fulfilment and compliance with certain standards or requirements ought to be realised and verified.Generally, products, services, processes. persons and also systems can be certified. Usually, the certifications and the […]
Mechanical pressure switches: What principle do they focus on?
Mechanical pressure switches in compact design ensure safe pressure monitoring in, for instance, pumps, compressors and mobile working machines. Whatever the application, they function relative to the principle of the preloaded spring, with a diaphragm or perhaps a piston as the measuring element.Mechanical pressure switches including the PSM01 (see illustration) are constructed relative to the […]
Active and passive temperature compensation of pressure sensors
How does an active or passive temperature compensation of pressure transmitters actually work? High-quality pressure transmitters, especially those found in precision critical applications, are almost always provided with an individual temperature compensation. But what is actually the difference between a dynamic and a passive temperature compensation of the sensors?Passive temperature compensation: Parts of the characteristic […]
Selection criteria for dial thermometers (3): Capillary
Bimetal or gas-actuated – the question of the suitable dial thermometer for the respective process can only be answered in a case without comparison: Only gas-actuated thermometers can be combined with a capillary.Dial thermometer with capillary – This combination is only possible with a gas-actuated instrument.In In the reaction to a temperature change, both dial […]
