WARNING!
Ensure that the calibration cover is removed after calibration is complete. This cover is intended to block the flow of
ambient air into the sensor during calibration, and in normal operation must ALWAYS be removed.
Failure to follow this warning can result in serious personal injury or death.
For applications where access to the HART signal is needed in hazardous areas, MSA provides the HART junction box
with intrinsically safe HART port (→
Figure 20 HART Module
The explosion-proof port allows access via a HART hand-held controller using the cable shown above (part number
10081441).
