As an integral component of a Reciprocating Compressor Condition Monitoring and Asset Management System, this transducer pairs with the 3500\/77M Cylinder Pressure Monitor and System 1 Plant Asset Management Software to deliver accurate, reliable data for predictive maintenance.\u003c\/p\u003e\u003cp\u003eManufactured in the U.S.A., the 165855-15-CN features a robust design that thrives in harsh chemical environments. Its patent-pending construction ensures continued accuracy even after prolonged cycling over large pressure gradients, and it withstands over-pressure upsets without diaphragm degradation. When operating pressure returns to the specified range, the transducer resumes normal function—minimizing downtime and protecting your investment.\u003c\/p\u003e\u003ch2\u003eKey Technical Specifications\u003c\/h2\u003e\u003cp\u003eThe 165855-15-CN offers a comprehensive set of performance parameters tailored for demanding compressor applications:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range:\u003c\/strong\u003e 0 to 6.8\/17\/34.5\/69\/172\/345\/689 bar (0 to 100\/250\/500\/1000\/2500\/5000\/10,000 psia)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Scale Output:\u003c\/strong\u003e 10 ± 0.3 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero Output:\u003c\/strong\u003e 0.5 ± 0.1 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 18 to 30 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Current:\u003c\/strong\u003e \u0026lt; 15 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 0 Hz to 5500 Hz ± 1 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLinearity, Hysteresis, Repeatability:\u003c\/strong\u003e ±0.3 %FS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -40 to 85°C (electronics housing), -40 to 150°C (sensor head)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProof Pressure:\u003c\/strong\u003e 1.5X Full Scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurst Pressure:\u003c\/strong\u003e 3X Full Scale (2X FS on 689 bar\/10,000 psia units)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Rating:\u003c\/strong\u003e Designed to meet NEMA 4X and IP67 conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThese specifications ensure reliable operation in extreme conditions, making the Bently Nevada 165855-15-CN a trusted choice for continuous monitoring.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe 165855-15-CN is purpose-built for reciprocating compressors found in oil \u0026amp; gas, petrochemical, and power generation facilities. It excels in measuring cyclic pressure changes, enabling early detection of valve leaks, ring wear, and other mechanical issues. By integrating with System 1 software, operators gain actionable insights that reduce unplanned outages and extend equipment life.\u003c\/p\u003e\u003cp\u003eIts ability to handle over-pressure events without diaphragm degradation makes it ideal for processes with frequent upsets. The transducer's compatibility with a wide range of media—including hydrogen sulfide, natural gas, and ammonia—expands its utility across diverse chemical environments.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eProper installation is critical for optimal performance. The wetted surface of the 165855-15-CN typically mounts into an isolation valve or pressure indicator port on the compressor. A special adapter, such as the 166393 adapter, provides a secure seal between the port and the transducer. The electronics housing is separated from the wetted surface by 1 meter of cable, allowing the electronics to be secured on or near the compressor for best results.\u003c\/p\u003e\u003cp\u003eAll transducers feature a 7\/8-14 UNF thread. Ensure the mounting torque does not exceed 68 N-m (50 lbf-ft) to prevent damage. The transducer is designed to meet IP67 for moisture ingress; however, the connector should remain dry. Avoid overtightening and always verify the O-ring material is compatible with your process media.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine inspection of the transducer and its cable is recommended to maintain accuracy. Check for signs of corrosion or mechanical damage, particularly on the sensor head. The robust design minimizes the need for frequent recalibration, but periodic verification against a known pressure source ensures long-term reliability.\u003c\/p\u003e\u003cp\u003eThe transducer's ability to recover from over-pressure events without diaphragm degradation reduces maintenance frequency and associated costs. By choosing the Bently Nevada 165855-15-CN, you invest in a component that supports continuous operation and lowers total cost of ownership.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting a replacement or upgrade, verify the pressure range and agency approval options. The 165855-15-CN model specifies a pressure range of 0 to 172 bar (0 to 2,500 psia) with armor, and the CN approval is country-specific. Confirm compatibility with your existing 3500\/77M monitor and System 1 software.\u003c\/p\u003e\u003cp\u003ePLC Source PRO is your reliable supplier for genuine Bently Nevada parts, ensuring authentic components that meet original specifications.
