6.6.1 Setting two sensors for differential measurement
Two analog sensors must be installed and connected electrically to measure a parameter at two different locations in a system.
The pressure, temperature and flow parameters can be used for differential measurement.
•
Set the analog inputs according to the measured parameter:
Parameter Sensor 1, measured parameter Sensor 2, measured parameter
Pressure, option 1 Inlet pressure Discharge press.
Pressure, option 2 Press. 1, external Press. 2, external
Flow Pump flow Flow, external
Temperature Temperature 1 Temperature 2
If you want to use the Con. diff. press. , Con. diff. temp. or Const. flow rate control modes, you must configure both sensors
as Feedback sensor .

In order to set the Pt100/1000 input for a feedback sensor, we recommend that you do this via the "Assisted pump setup" menu. If you wish
to set a Pt100/1000 input for other purposes, you can do this manually.
Function
You can set the inputs to these functions:
•
Not active
• Feedback sensor
The sensor is used for the selected control mode.
• Setpoint influence
The input signal is used for influencing the setpoint.
• Other function
The sensor input is used for measurement or monitoring.
Measured parameter
Select one of the below parameters to be measured in the system by the sensor connected to the input.
