Product Performance
All three products are originalBently Nevada spare parts, which work together to be compatible withBently Nevada 3500 frame system and various key equipment such as reciprocating compressors and gas turbines. They are stably powered, easy to install and maintain, can quickly realize accurate monitoring of rod position, rod drop and hyper-compressor status, are easy to replace, can quickly restore the system monitoring function, and ensure the safe and continuous operation of industrial equipment.
Equipped with a dedicated signal processing chip, it can stably receive 1 to 4 eddy current transducer signals, with high measurement accuracy. The sensitivity can be flexibly configured according to the rod material, and it can accurately process dynamic and static position parameters, generate key data such as peak-peak displacement, gap, and 1X/2X amplitude, meeting the high-precision requirements of industrial equipment condition monitoring.
Supports 3500 frame configuration software programming, channels can be configured in pairs, up to two monitoring functions can be realized, integrates a complete alarm mechanism, alarm points can be flexibly set, and alarm delay can be accurately programmed, which can timely feedback equipment abnormalities, provide reliable support for equipment protection, and avoid equipment damage.
Adopting industrial-grade flame-retardant board for reinforced packaging, it has strong anti-electromagnetic interference ability, complies with a number of international electromagnetic compatibility standards, has strong adaptability to wide temperature environment, can operate stably for a long time in industrial environments from -30℃ to +65℃, suitable for harsh heavy industrial scenarios with high dust and high interference. Key components have passed strict screening and have a long service life.
It has complete LED status indication, fault diagnosis and signal buffer output functions, which can feedback module operation status, communication status and bypass mode in real time, facilitating maintenance personnel to quickly locate and troubleshoot problems. The modular design is convenient for system expansion and maintenance, and can complete expansion without major modifications to the existing monitoring system, adapting to the needs of industrial equipment monitoring scenarios of different scales.
