165855 Cylinder Pressure Transducer
Bently Nevada* Asset Condition Monitoring
Description
The Cylinder Pressure System consists of the 165855 Cylinder Pressure
Transducer and the 146824 Interconnect cable. It is intended for measuring the
cyclic absolute pressure changes inside a reciprocating compressor cylinder.
This transducer is an integral part of a Reciprocating Compressor Condition
Monitoring and Asset Management System when utilized with our 3500/77M
Cylinder Pressure Monitor and System 1* Plant Asset Management Software.
The Cylinder Pressure Transducer has a robust design for high reliability in harsh
chemical environments. The unique, patent-pending design also allows the
transducer to continue to provide an accurate pressure reading, even after
being continually cycled over large pressure gradients for an extended period of
time. The transducer can also withstand over-pressure situations caused by
application upsets without diaphragm degradation, returning to normal
operation when the operating pressure returns to the transducer’s specified
operating pressure range. The Cylinder Pressure Transducer is also designed to
meet NEMA 4X and IP67 conditions for moisture ingression.
The wetted surface of the transducer is typically installed into an isolation valve
or similar pressure indicator port on the compressor. A special adapter is usually
required to provide a seal between the pressure indicator port and the
transducer (such as the 166393 adapter). The electronics portion of the Cylinder
Pressure Transducer is separated from the wetted surface by 1 metre of cable.
The electronics must be secured on or near the compressor for optimal
performance.
Each pressure sensor will be shipped with pressure-temperature compensation
data in order to optimize the measurement. Inputting the supplied data points
into the 3500/77 Cylinder Pressure Monitor can minimize the operating
temperature effects on the transducer.
