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 instrument from over-pressure a suitable protection device (such as a relief
valve or bursting disc) must be fitted to prevent over pressurization.
On instruments without a negative supply, the positive pressure discharges from the system
to atmosphere through the negative supply port. Pipe the negative port to a safe discharge
area or fit a diffuser to the negative port.
During system pressure vent operations, the pressure discharges from the system to
atmosphere through the negative and vent ports. Pipe both ports to a safe discharge area or
fit a diffuser to the negative port.
Pneumatic Connection Examples (Ref: Figures 2-3, 2-4 and 2-5)
The examples that follow show a single channel connection detail, using supply equipment
described above.
