What is a pressure transmitter?
Anna GriesThe manufacturers of pressure sensors use many different terms for the various designs of measuring instruments, such as pressure sensor, pressure transmitter, pressure transducer, etc. At WIKA, the term: “pressure transmitter” is commonly used to refer to a …
Ingress Protection for Pressure Sensors – Definition of IP protection types
Dominik LorenzA frequently recurring question is about the definition of the so-called IP protection types or sometimes referred to as “IP rating”. The IP ingress protection types provide a system that describes how the housing of electrical equipment is protected against the …
Pressure equipment directive 97/23/EC PED – Pressure limits 0.5 bar and 200 bar for pressure sensors and pressure transmitters
Dominik LorenzIn connection with the pressure equipment directive 97/23/EC (PED), a pressure limit of 200 bar is often mentioned. But what does this limit mean for manufacturers and/or companies that place pressure sensors, pressure transmitters and pressure equipment on the market? …
The most common measuring principles for pressure sensors: thin-film, thick-film and piezoresitive sensors
Michèle BeyerAlthough, for most applications, the choice of sensor measuring principle or functional principle of the pressure sensor is not important, we are still often asked about how the sensor elements integrated in our pressure sensors and pressure transmitters work. First of …
