Compressor Pressure Transducer
The compressor 4-20 mA sensor is the standard sensor for collecting compressor pressure measurements
with the Windrock 6400 analyzer.
The pressure transducer is typically connected to a Kiene valve or other indicator valve type on the
compressor cylinders.
Typical full scale ranges are 300, 500, 1,000, 2,000, 3,000, 5,000 psig.
The quick-connector should be cleaned periodically or whenever contamination of the pressure passage or
diaphragm may have occurred (such as during testing on units within a refinery). Brake cleaner works well for
this.
Note: Always zero the compressor pressure sensor prior to taking data, and periodically during data collection,
to compensate for thermal shift.
Note: Do not remove the main sensor body from the right-angle adapter due to specific torque limits are
required for re-installation.
