Thermo Scientific DensityPRO User Manual 3-15
The DensityPRO family of gauges will accept a process temperature input from a 3- or
4-wire RTD, as a 4–20 mA signal from an existing temperature transmitter, or as a
manual value entered into the transmitter by the operator.
1. Select Temperature Compensation and click the Next button to bring up the
following screen. If your application requires temperature compensation, ensure
that the parameters on this screen are entered correctly.
Figure 3-11. Temperature Setup
Note: To use temperature compensation, specify material densities that are
correct at a reference temperature outside the expected process temperature
range. The default reference temperature is 20°C (68°F).

Temp. Input Source – In order for the temperature compensation function to
work, a temperature signal input is required. The DensityPRO devices will
accept input directly from an RTD or from a 4–20 mA temperature
transmitter. Alternately, a fixed temperature can be manually specified.

Temperature Unit – Specify the temperature units as ºC or ºF.

Temp Hold Constant (ºC) – If Manual Value was selected as the input source;
enter the constant temperature value in this textbox. The default value is 20º.

Temperature at 4 mA and 20 mA – Input the temperatures for both 4 mA and
20 mA in these textboxes.
2. Click the Next button to proceed.
