BENTLY 3500/92 136180-01 monitor provides mechanical protection
3500/92 136180-01 Reference Information
These fields contain information that indicates which module you are configuring. Channel The number of the channel being configured (1 through 4). Slot The location of the monitor in the 3500/92 136180-01 rack (2 through 15). Rack Type Identifies the type of Rack Interface Module installed in the rack (Standard or TMR).
3500/92 136180-01 Clamp
3500/92 136180-01 Value The value that a proportional value goes to when that channel or proportional value is bypassed or defeated (For example when a problem occurs with the transducer). The selected value can be between the minimum and maximum full-scale range values. (1X and 2X Phase Lag have available values of 0 to 359 degrees.) Only the values available from the Recorder Outputs, Communication Gateway and Display Interface Module are clamped to the specified value when the proportional value is invalid.
3500/92 136180-01 Recorder Output
The proportional value of a channel that is sent to the 4 to 20 mA recorder. The recorder output is proportional to the measured value over the channel full scale range. An increase in the proportional value that would be indicated as upscale on a bar graph display results in an increase in the current at the recorder output.

3500/92 136180-01 Enable
An enabled proportional value specifies that the value will be provided by the channel ( enabled, disabled). Direct Data which represents the overall peak to peak vibration. All frequencies within the selected Direct Frequency Response are included in this proportional value. Gap The physical distance between the face of a proximity probe tip and the observed surface. The distance can be expressed in terms of displacement (mils, micrometres) or in terms of voltage. Standard polarity convention dictates that a decreasing gap results in an increasing (less negative) output signal. 1X Ampl In a complex vibration signal, notation for the amplitude component that occurs at the rotative speed frequency. 1X Phase Lag In a complex vibration signal, notation for the phase lag component that occurs at the rotative speed frequency.
The Bently 3500 online vibration monitoring system from the United States is used for mechanical protection applications, for vibration monitoring of large and medium-sized rotating machinery such as steam turbines, compressors, fans, water pumps, coal mills, gearboxes, motors, etc. It is widely used in steel, power, metallurgy, petrochemical petroleum, natural gas, petrochemical, chemical and other related industrial fields. The highly modular design of the system includes:
Bently3500/05 Instrument Frame
Bently3500/15 power supply
Bently 3500/20 Framework Interface Module
