Emerson Process Management 2400S guide

Pressure Compensation and Temperature Compensation

There are two ways to configure external temperature compensation:

•If the operating temperature is a known static value, you can configure that value in the transmitter.

•If the operating temperature varies significantly, you must write a temperature value to the transmitter at appropriate intervals, using an appropriate output assembly. See Section 9.4.

Note: Ensure that your temperature value is accurate, or that your temperature measurement device is accurate and reliable.

To enable and configure external temperature compensation:

•With ProLink II, see Figure 9-3.

•With a DeviceNet tool, see Figure 9-4.
