Plausibility monitoring in pressure measurement
Extended process data from pressure transmitters allow for advanced diagnostics to improve process safety
Whether a pressure transmitter measures accurately and with long-term stability depends not only on the design, but also on the process stability. Process variables such as temperature or ambient pressure can affect gauge or differential pressure (DP) measurement, especially if these parameters are “out of spec” and left unattended.
OPTIBAR pressure and DP transmitters offer diagnostics for additional process information and plausibility checks of running applications. This includes integrated line pressure measurement (Pabs) and data logging functions (e.g. on parameter changes) that allow operators to check if an application is being operated properly.
