Pneumatic Connections

Clean all pipelines to remove dirt and scale before installation.
Apply a minimum amount of pipe compound to the male threads of
the air line only. Do not use teflon tape as a sealant. Start with the
third thread back and work away from the end of the fitting to avoid
contaminating the transducer.
The inlet and outlet ports are labeled on the ends of the transducer.
Tighten all connections securely. Avoid undersized fittings that will limit
the flow through the transducer. For more information, see Figure 2.

NOTE:
Instrument quality air, per ISA Standards S7.3-1981, is required.
Use a filter to remove dirt and liquid in the air line ahead of the
transducer. If an air line lubricator is used, it MUST be located
downstream to avoid interference with transducer performance.
The user is responsible for ensuring that the environment in which
the unit is installed and the operating gas are compatible with the
materials in the transducer.

Electrical Connections

Make connections to the Terminal Block, Conduit Connector or the DIN
Connector as shown in Figure 9.
