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 …
CANopen: digital instead of analogue signals
Markus Heidl | Know-howUnlike an analogue signal, which as a physical quantity can take on continuous values, a digital signal consists of discrete values. Personally, I always think of long strings of zeros and ones floating through space: 0101 0111 0100 1001 0100 1011 0100 0001 0011 1101 …
