Measurement Linearisation

The Toolkit includes applications designed for specific controllers - notably for flow controllers (where the control valve causes nonlinearity) and level controllers (on horizonatl vessels). This module has a more general use. The user pastes in historical data comprising the manipulated variable (controller output) and the corresponding process variable). The software will show whether the relationship is sufficiently linear for good control. If not, it will generate a linearisation function that can be used to condition the PV.
