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
[ fig. 26] 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.
These insect screens are not included in the cFMus performance approval.
CAUTION
Use of these inserts will significantly increase the sensor response time
to ambient gas conditions. Ensure that the operational conditions are ap-
propriate for use of these screens.
These screens can be used as an insect guard.
