Unfortunately, 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 …

Integrated M12 Y-connector vs. external T-piece: Advantages/ comparison in CANopen pressure sensors
| Jürgen Reiser | GeneralThe main reason for using a pressure sensor with CANopen interface compared to customary analogue sensors is the low degree of wiring required and the high reliability of signal transmission. The data and power cables of the CAN bus are combined in a single shielded …
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 …
