Plausibility monitoring in pressure measurement
Extended process data from pressure transmitters allow for advanced diagnostics to improve process safety
Challenge
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.
Solution
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.
Safety Benefits
Additional information on process variables to check plausibility of pressure transmitter performance and process stability
Advanced diagnostic features and event logger functionality incl. monitoring of resets, failures, change of parameters, pressure peak counter, etc.
Integrated line pressure measurement (Pabs)
Extensive process data to identify irregular events that pose a risk to measurement accuracy and process safety
