Although, 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 …
Pressure sensor
Definition of the IP68 rating in theory and practice
Michèle Beyer | GeneralUnfortunately, we are asked too rarely regarding the specification of the IP68 rating for our pressure sensors and submersible pressure transmitters, i.e. how deep such an instrument may be submersed. However, this is not only a very meaningful question but also a …
The response time behaviour of pressure sensors: How is the response time defined and what is the definition of the rise time?
Enrico Bossart | PressureThe response time of pressure sensors is reflected in a large number of varying parameters, such as the response time, settling time or rise time in specifications or data sheets. In general, it can be assumed that the response time is defined as the interval required …
The definition of MTTF and MTBF – and what is the difference?
Anna Gries | GeneralThe two definitions of MTTF and MTBF differ only slightly. Written out, the two acronyms read as follows: Mean Time To Failure (MTTF) – i.e., the component/instrument will be replaced, following a failure Mean Time Between Failures (MTBF) – mean time between …
Temperature coefficients (TC) of pressure sensors
Anna Gries | GeneralSince temperature affects the measuring accuracy of a pressure sensor, there always remains a small temperature error in the rated temperature range despite a wide range of compensation measures. This error is often expressed in the data sheets of manufacturers of …
