165855-15-CN
Bently Nevada
Overview
The 165855-15-CN is a Cylinder Pressure Transducer from Bently Nevada. It is part of Bently Nevada's industrial automation product portfolio.
Application & Technical Notes
As a cylinder pressure transducer, the 165855-15-CN is intended for deployment in panel-based control cabinets and machine enclosures where the Bently Nevada product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Bently Nevada platform.
Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.
Maintenance & Diagnostics
Avoid condensation — the rated humidity is 95% condensing on exposed; store and operate the module in a dry, pollution-degree-appropriate enclosure. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the 165855-15-CN, distinguish three supply tiers: (1) genuine Bently Nevada stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your Bently Nevada product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications
165855-15-CN | Bently Nevada | Cylinder Pressure Transducer
Description
| Note | 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.
