Functional Description
3500/40M is a proximitor Monitor designed and developed by Bently Nevada. The proximitor Monitor is a four-channel monitor that accepts input from proximity transducers from Bently Nevada, conditions the signal to provide various vibration and position measurements, and compares the conditioned signals to user-programmable alarms. It condition input signals effectively. By doing so, it transforms raw data into a range of valuable measurements. These measurements encompass not only vibration data but also critical position measurements. This versatility is particularly advantageous for industries where comprehensive insights into machinery behavior are essential for predictive maintenance and operational optimization. The Proximitor Monitor offers users the flexibility to set custom alarms according to their specific operational requirements. These alarms serve as a safeguard, promptly notifying operators and maintenance personnel of any deviations from predefined thresholds. By providing real-time alerts, this monitor plays a pivotal role in preventing potential issues before they escalate, thus minimizing downtime and reducing maintenance costs.
Configurable Functions
- Eccentricity Measurement: The monitor can assess and report on eccentricity, helping operators identify any deviations from optimal shaft alignment, a critical factor in machinery reliability.
- Radial Vibration Analysis: Precise monitoring of radial vibration allows for early detection of irregularities that could lead to equipment failure, enabling timely intervention.
- REBAM (Reverse-Eccentricity Bore Alignment Monitor): This function aids in assessing the alignment of machine components, ensuring that they meet the necessary standards for safe and efficient operation.
- Thrust Position Monitoring: Keeping tabs on thrust position is crucial in industries where axial forces play a pivotal role. Monitoring this parameter helps prevent premature wear and tear.
- Differential Expansion Measurement: This function helps monitor the expansion and contraction of critical machine components, ensuring they remain within acceptable limits.
Features
- The proximitor Monitor's primary function is to provide machinery protection by continuously comparing monitored parameters to configured alarm setpoints to drive alarms.
- Important machine data for both operations and maintenance personnel Depending on the configuration, each channel typically conditions its input signal to generate various parameters known as static values. You can set alert and danger setpoints for each active static value, as well as alert and danger setpoints for any two active static values.
- The monitor channels are programmed in pairs. Up to two of these functions can be performed by the monitor channels at the same time. Channels 1 and 2 can do one thing, while channels 3 and 4 can do something else.
Alarms
Alarm Setpoints
- Set alert levels for each value measured by the monitor and Danger setpoints for any two of the values measured by the monitor using Rack Configuration Software.
- For each measured value, alarms can be set from 0 to 100% of full-scale. When the full-scale range exceeds the transducer's range, the setpoint is limited by the transducer's range.
Accuracy of alarm setpoints
- Within 0.13% of the desired value
Product attributes
- Four Channel Monitor
- Accepts Input from Proximity Transducers
- Various Static Value Parameters
Frequency Response
- Direct Filter: This component allows users to program a single-pole filter with adjustable frequency settings. It covers a wide range, from 4 Hz to 4000 Hz or 1 Hz to 600 Hz. This means that the device can attenuate or emphasize signals within this frequency range according to the user's preferences.
- Gap Filter: The gap filter is designed to specifically affect frequencies around 0.09 Hz. It attenuates these frequencies by -3 dB (decibels), which is a measure of signal strength reduction. This indicates that the filter can be employed to reduce the amplitude of signals around 0.09 Hz, shaping the overall frequency response.
- Not 1X Filter: This filter operates in a unique range from 60 cycles per minute (cpm) to 15.8 times the running speed. It employs a Constant Q notch filter, meaning it can effectively remove or reduce signals within a narrow frequency range. With a minimum rejection of -34.9 dB in the stopband, it can significantly suppress unwanted frequencies within its designated range.
- Smax: Smax defines a range from 0.125 to 15.8 times the running speed. This range is most likely related to speed measurements, and the device seems to provide some form of processing or filtering for signals within this speed range.
- 1X and 2X Vector Filter: These filters are particularly interesting as they can work with signals that are multiples of the running speed (1X and 2X). They also utilize a Constant Q Filter, implying that their attenuation or emphasis on specific frequencies remains consistent across different center frequencies. With a minimum stopband rejection of -57.7 dB, these filters can effectively eliminate or substantially reduce unwanted signal components in their respective frequency ranges.
