The calibration of analogue signals from myriad sensors and transducers in a process plant is essential not only to ensure correct readings on instruments but also for the feedback signals required for stable process plant operation. A typical process plant will generate outputs to several sensors and transducers as shown in the above diagram. These outputs include process parameters like temperature, pH, pressure, flow and level, and mechanical parameters from devices like tachometers, accelerometer and position encoders, amongst others.
