Pressure switches with metal bellows: Stable repeatability, no risk of leakage
Jing Lyu | Know-howWhat advantages do pressure switches with metal bellows offer and what is the basis for these? The advantages are based on the seamless design of their measuring system. This solution enables permanently stable repeatability and, at the same time, eliminates the risk …
Diaphragm seal systems with TRI-CLAMP® connection are NovAseptic® compatible
Tobias Hench | Know-howIn sanitary applications, diaphragm seal systems ensure a safe and precise monitoring of the process pressure. WIKA therefore also offers welded units of diaphragm seal and measuring instrument with TRI-CLAMP® connection for process integration. A combination of this …
Pressure sensor with I²C communication – possibilities and boundary conditions
Christian Wirl | Know-howI²C was designed to communicate over short distances between printed circuit boards and is a simple, 8-bit serial data bus. In the meantime, it is not only PCB-mountable pressure sensors that use the I²C signal for data transfer, but also pressure sensors remote from …
Pressure and temperature measurement at extremely low ambient temperatures
Christopher Ott | Know-howStandard pressure gauges and thermometers generally cope with ambient temperatures down to -40 °C. But what must be the features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using …
