Figure 3: Pneumatic Connections - Typical Use Cases
1.1 Supply Equipment
Pneumatic supplies should have isolation valves and, where necessary, conditioning
equipment. The positive pressure supply should be regulated to between 110% of the full-
scale pressure range and MWP stated on the control module.
To protect the control module, for ranges above 100 bar, from over-pressure a suitable
protection device (such as a relief valve or bursting disc) must be fitted to limit the applied
supply pressure to below the MWP.
On instruments without a negative supply, the positive pressure discharges from the system
to atmosphere through the negative supply port. Fit the diffuser to the negative port to
diffuse airflow.
During system pressure vent operations, the pressure discharges from the system to
atmosphere through the vent port. Fit a diffuser to the vent port to diffuse airflow.
