Product Details:

The BENTLY NEVADA 3500/77M four-channel reciprocating cylinder pressure monitor module belongs to Bently Nevada 3500 TSI machinery protection system. It adopts front card plus rear terminal base split design and can be installed in any free slot of the 3500 rack. This module receives signals from approved cylinder pressure transducers for reciprocating compressors. It can calculate suction pressure, discharge pressure, maximum pressure, minimum pressure, compression ratio, peak rod compression and peak rod tension. Each channel can set Alert alarm, and two selected variables support Danger trip alarm logic. When cylinder pressure exceeds preset threshold, the module sends alarm signals to rack relay modules to trigger machinery alarm. It cooperates with TDI module to upload pressure waveform data to System 1 software for reciprocating compressor thermodynamic performance analysis and fault diagnosis. Front panel LED indicators display module OK status, bypass state and channel alarm state for on-site inspection. Built-in self-diagnosis function can detect sensor open circuit, short circuit and signal loss faults. It supports hot swapping during normal rack operation, maintenance staff can replace the module without shutting down the whole TSI system. It complies with API 670 and API 618 standards, widely applied in petrochemical industry, used for reciprocating compressor cylinder pressure online monitoring and equipment protection.
