Pressure Systems, Inc. Model 9116 User’s Manual

The following guidelines should be used when installing pressure connections to the Model 9116 Intelligent Pressure Scanner modules.

●Always wear safety glasses when working with pressurized lines.

●Ensure that user input pressure will not exceed the proof pressure ratings of the corresponding instrument transducer. Applying excessive pressure to measurement inputs can permanently damage the pressure transducers.

●Ensure that all tubing material is rated for the expected pressure and

environmental conditions. Failure to use the proper tubing material may result in ruptured lines and possible personal injury.

●Ensure all high pressure lines are properly secured.

●Place retaining springs over all bulge tube fittings to ensure pneumatic lines remain attached and leak free. Springs should be pushed down on connections so that half of the spring length extends past the tube bulge.

Warning: Introduction of contaminants or corrosive materials to the module pneumatic inputs may damage module transducers, manifolds, and O-ring seals.

2.3.6.1RUN Mode Inputs

The standard pneumatic tubing plate for the Model 9116 contains sixteen numbered pneumatic input channels. These numbered inputs are attached to corresponding pressure transducers inside the instrument and should be pneumatically attached to the pressure measurement points under test.

The standard tubing plate also contains an input labeled RUN REF. The RUN REF input is pneumatically connected to the reference side of all internal DH200 pressure transducers. The RUN REF connection is used for situations where all channels have one reference pressure. The reference pressure may be as high as 250 PSI (1720 kPa). See the Model 9116 Data Sheet for detailed specifications. This input may also be left unattached to provide atmospheric reference pressure.

When using instruments with the reference per channel option (true differential), two pneumatic inputs will be provided for every numbered channel. These inputs are labeled ‘P’ and ‘R’. The ‘P’ connection is the test pressure input. The ‘R’ connection is the transducer reference input pressure. Since each channel has its own reference pressure input, the RUN REF input is not provided on the true differential tubing plate.
