ATC Technology reaches outstanding results in accuracy in diaphragm seal applications
30 August 2017
High-precision pressure measurement with PASCAL Ci4 and ATC technology (ATC = Active Temperature Compensation) reduces the temperature error by 90%
Diaphragm seals are frequently used in the process industry for pressure measurements to protect the measuring device against aggressive media or to create a gap-free process connection. With the help of diaphragm seals, every measurement task can find its solution. A drawback is that the pressure transmission fluid used in the device expands as a result of the process heat. This generates a restoring force depending on the rigidity of the diaphragm, which is received as an error in the pressure measurement.
To remedy this, LABOM has developed a further compensation process to create a solution for this problem. The temperature of the pressure transmission fluid is recorded with an additional temperature sensor (ATC technology (ATC = Active Temperature Compensation)).
Resulting errors can now mathematically be corrected immediately, so that the temperature error can be reduced by 80-90% with small diaphragm seals (in a stationary state)?.
