Insect Guard Remote Calibration Inserts
For applications where HART is being used for calibration and the sensor is located in a remote location where use of the calibration cover is not practical, optional screen inserts are available. These inserts snap into the environmental guard (→ Figure 28 ) and permit a very slow diffusion of gas through the tight mesh screens. This allows enough zero and span gas to be retained in the environmental guard for the calibration procedure to be accurate for still air applications.
WARNING!
Use of these inserts will increase the sensor response time to ambient gas conditions. Ensure that the conditions are appropriate for use of these screens.
Failure to follow this warning can result in serious personal injury or death.
These screens can be used as an insect guard.
For remote calibrations the HART Remote Calibration Kit is also recommended (P/N 10122783).
