Virtual process values (mathematical functions)
In addition to "real" process values, which are provided by connected physical sensors or analog
inputs, mathematical functions can be used to calculate a maximum of 6 "virtual" process values.
The "virtual" process values can be:
• Output via a current output or a Fieldbus
• Used as a regulating control variable
• Assigned as a measured variable to a limit contactor
• Used as a measured variable to trigger cleaning
• Displayed in user-defined measuring menus.
The following mathematical functions are possible:
• pH calculation based on two conductivity values acc. to VGB 405 RL, e.g. in boiler feed water
• Difference between two measured values from different sources, e.g. for membrane monitoring
• Differential conductivity , e.g. monitoring the efficiency of ion exchangers
• Degassed conductivity, e.g. for process controls in power plants
• Redundancy for monitoring two or three redundantly measuring sensors
• rH calculation based on the measured values of a pH and an ORP sensor
