DensityPRO Setup
Time Constants
To set the primary and alternate time constants using the NI-FBUS
Configurator:
Time Constants
1. Go to AI_TRANSDUCER > Root Menu > 1 Setup > 2 Time
Constant > Time constant setup .
2. Remove the loop from automatic control as prompted.
3. Primary Time Constant value: Set the primary time constant.
4. Alternate Time Constant value: Set the alternate time constant.
5. Current Time Constant: Enter 1 to use the primary time constant or 2
to use the alternate.
6. Time constant setup is complete.
Temperature
Compensation
Setup
If temperature compensation is required, access the Temp. Compensation
Setup menu.
Setup consists of the following steps:
1. Go to AI_TRANSDUCER > Root Menu > Setup > 3 Temperature
Comp. Setup > Temp. Compensation Setup.
2. Remove the loop from automatic control.
3. Temp. Input Source: Select the source of the temperature input signal.
4. Temp. hold constant: Enter the temperature hold constant if you
selected Manual entry above.
5. Temperature comp polynomial: Choose a user defined or predefined
temperature compensation polynomial. The gauge uses polynomial
equations to compute the change in density of the process material(s) as
a function of the change in temperature relative to the reference
temperature. If you select user defined, temperature compensation
polynomials are defined based on the material type selected.
