A 0–100 psia armored cylinder pressure transducer for cyclic absolute-pressure measurement on reciprocating compressors.

Model Information

Bently Nevada 165855-11-01 is a cylinder pressure transducer designed to measure the changing absolute pressure inside a reciprocating-compressor cylinder. Its fast cyclic signal is used by the 3500/77M monitor to evaluate the pressure event through each revolution rather than treating the cylinder as a steady process-pressure point.

Ordering code 11 identifies the 0 to 6.8 bar, or 0 to 100 psia, armored measurement configuration. Code 01 selects the combined CSA, ATEX and IECEx approval option. The 7/8-14 UNF process connection and defined mounting bore let the sensing diaphragm communicate with the cylinder while the armored cable leads to the specified interconnect path.

Bently Nevada 165855-11-01 is normally connected through interconnect cable 146824 to a 3500/77M channel. A serviceable installation therefore includes more than the transducer: the cylinder port, isolation arrangement, cable, channel setup and crank-angle reference must all support the intended pressure-versus-angle measurement.

Application Scenarios

Bently Nevada 165855-11-01 turns each compression cycle into information that can distinguish process behavior from mechanical timing problems.

Load analysis

Follow pressure through the full revolution

A single pressure value cannot show when suction closes, compression rises or discharge begins. The 165855-11-01 waveform is evaluated against crank angle so operators can compare the shape, peak and timing of repeated cycles.

Valve behavior

Use waveform changes to focus inspection

A delayed rise, altered pocket of pressure or changing discharge event can direct attention to valves, clearance, leakage or process conditions. The transducer supports diagnosis, while final maintenance decisions should still combine operating context and other machine measurements.

Cylinder comparison

Keep channels comparable

When several cylinders are monitored, matching ranges, channel scaling and angular reference make comparisons useful. A different zero, cable fault or port condition can look like a process imbalance, so configuration consistency is checked before conclusions are drawn.

System Integration

The value of Bently Nevada 165855-11-01 depends on the pressure path, electrical connection and monitor reference remaining synchronized.

Keep the pressure passage clear and controlled

The mounting bore and isolation valve must expose the sensor to cylinder pressure without an unintended restriction or leak. Before removal, isolate and depressurize the connection under the site procedure because trapped pressure can remain even after the compressor stops.

Maintain the documented channel chain

Use the specified 146824 interconnect cable to the 3500/77M input, support the armored lead and protect connectors from oil and moisture. Channel range and transducer option must agree so the displayed engineering units match the installed 0–100 psia device.

Correlate pressure with machine position

Cylinder-pressure interpretation requires a stable crank-angle reference. If phase alignment changes after tachometer or keyphasor work, verify the reference before treating a shifted event as a new valve or cylinder fault.

Common Product Questions

Why does Bently Nevada 165855-11-01 show a flat trace while the compressor is loaded?

For Bently Nevada 165855-11-01, first confirm that the isolation path is open, the pressure passage is not blocked and the 146824 cable is connected to the configured 3500/77M channel. A closed valve or incorrect channel range can create a flat trace without a failed sensor.

What can make Bently Nevada 165855-11-01 indicate an incorrect peak pressure?

Bently Nevada 165855-11-01 can appear incorrect when the channel range does not match code 11, the mounting passage is restricted, the sensor is thermally unsettled or the angular reference is misaligned. Compare a known operating condition and verify configuration before recalibration decisions.

How should Bently Nevada 165855-11-01 be removed safely?

Before removing Bently Nevada 165855-11-01, stop and secure the compressor, isolate the cylinder connection and prove the passage is depressurized. Disconnect the electrical path only after the hazardous-area and site procedures are satisfied, then protect the exposed bore from contamination.

Why can the waveform from Bently Nevada 165855-11-01 shift after keyphasor work?

Bently Nevada 165855-11-01 measures pressure, while the monitor places that pressure against an external crank-angle reference. If the reference probe or event marker moved, the waveform can shift horizontally even though the pressure transducer has not changed.

What should be preserved when replacing Bently Nevada 165855-11-01?

For Bently Nevada 165855-11-01, retain the complete ordering code, pressure range, approval requirement, channel scaling, cable routing and angular-reference setup. Photograph the connection and record a baseline trace before removal when operating conditions permit.

How can moisture-related faults around Bently Nevada 165855-11-01 be reduced?

Keep the Bently Nevada 165855-11-01 connector and cable termination clean, fully engaged and mechanically supported. The transducer has NEMA 4X/IP67 protection, but poor connector sealing or damaged armor can still allow contamination into the signal path.
