The 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 …

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 …
How does a pressure sensor behave in the overload area, that means outside the measuring range?
| Anna Gries | PressureI have often been asked about the behaviour of a pressure sensor outside the specified measuring range, that means in the overload area and what will happen if the overload limit of a pressure sensor is exceeded. This fact is described as follows in the book …
What is the functional principle of a resistive pressure transmitter?
| Anna Gries | PressureThe functional principle of a resistive pressure transmitter is very simple. The pressure sensor converts the mechanical pressure value into a proportional electrical signal. The pressure sensor typically consists of a stable main body and a (thin) diaphragm. The …
