مراقب سرعة النبض الترددي Bently Nevada 3500/70M

The Bently Nevada 3500/70M Recip Impulse Velocity Monitor is a 4-channel device used as part of the reciprocating compressor solutions package to monitor compressor crankcase and crosshead vibration. The monitor accepts input from seismic transducers, conditions the signal to derive vibration measurements, and compares the conditioned signals with user-programmable alarms. Programming each channel using the 3500 Rack Configuration Software allows for the following functions: impulse acceleration, acceleration 2, recip velocity, and low frequency recip velocity. The monitor channels are programmed in pairs and can perform up to two of the aforementioned functions at a time. For example, channels 1 and 2 can perform one function while channels 3 and 4 perform another or the same function. The primary purpose of the 3500/70M Recip Impulse Velocity Monitor is to provide machinery protection for reciprocating compressors by continuously comparing monitored parameters against configured alarm setpoints to drive alarms. Additionally, it provides essential reciprocating compressor machine information for both operations and maintenance personnel. Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. Alert setpoints can be configured for each active static value, and danger setpoints for any two of the active static values. Overall, the 3500/70M Recip Impulse Velocity Monitor offers reliable and effective monitoring of reciprocating compressor vibration, providing critical information for maintaining and protecting machinery.
