Chapter 9
Pressure Compensation
and Temperature Compensation
9.1 Overview
This chapter describes the following procedures:
• Configuring pressure compensation – see Section 9.2
• Configuring external temperature compensation – see Section 9.3
• Obtaining external pressure or temperature data – see Section 9.4
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.
Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
9.2 Pressure compensation
The Model 2400S DN transmitter can compensate for the effect of pressure on the sensor flow tubes.
Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure
change away from calibration pressure.
Note: Pressure compensation is an optional procedure. Perform this procedure only if required by
your application.
9.2.1 Options
There are two ways to configure pressure compensation:
• If the operating pressure is a known static value, you can configure that value in the
transmitter.
• If the operating pressure varies significantly, you must write a pressure value to the transmitter
at appropriate intervals, using an appropriate output assembly. See Section 9.4.
Note: Ensure that your pressure value is accurate, or that your pressure measurement device is
accurate and reliable.
