Bently Nevada 26313-02-09-03-05-01-01-01 Vibration Monitoring Module Product Specification
26313-02-09-03-05-01-01-01 is a factory-configured plug-in dual-channel vibration monitor module belonging to Bently Nevada classic 3300 series rack-mounted monitoring system, specially developed for continuous vibration and casing displacement measurement on large rotating machinery including steam turbines, centrifugal compressors, large blowers and generator sets deployed in thermal power, petrochemical, metallurgy and oil & gas industries. This module receives input signals from 3300XL eddy current proximity probes paired with matching preamplifiers, converts alternating eddy-current signals into standard vibration amplitude readings, executes over-vibration pre-alarm and dangerous trip logic, and outputs switch signals for equipment safety interlock protection to avoid catastrophic mechanical damage caused by excessive rotor vibration. Every finished unit undergoes full signal calibration, long-term temperature cycling aging and electromagnetic compatibility testing before factory shipment to guarantee stable measuring performance under severe cabinet working conditions with fluctuating ambient temperature, industrial dust and complex on-site electromagnetic interference. Measured vibration data can be transmitted via rack backplane bus to upper-level DCS and SIS monitoring platforms for centralized remote real-time display and historical data recording.

1. Product Overview
26313-02-09-03-05-01-01-01 is a factory-configured plug-in dual-channel vibration monitor module belonging to Bently Nevada classic 3300 series rack-mounted monitoring system, specially developed for continuous vibration and casing displacement measurement on large rotating machinery including steam turbines, centrifugal compressors, large blowers and generator sets deployed in thermal power, petrochemical, metallurgy and oil & gas industries.

2. Full Part Number Segmentation Definition
The complete part number 26313-02-09-03-05-01-01-01 consists of eight segmented parameter codes defined by original factory configuration rules, each section corresponds to fixed hardware and function setup:The base code 26313 represents core product series, which stands for dual-channel overall vibration monitor board designed for 3300 rack framework and eddy current transducer matching; the second segment 02 defines full-scale measuring range and unit configuration of vibration channel; the third segment 09 specifies matched transducer sensitivity parameter and preamplifier type matching specification; the fourth segment 03 sets internal relay contact form and alarm output definition; the fifth segment 05 stands for front panel indicator layout and hardware circuit revision version; the sixth segment 01 defines external terminal wiring structure mode; the seventh segment 01 refers to industry certification approval option setting; the final segment 01 indicates special factory customized parameter and production batch configuration. Modules with any different suffix segment codes differ in internal circuit parameter and calibrated range, and cannot be directly replaced on-site without professional parameter reconfiguration and recalibration.
3. Core Functional Features
This monitor is equipped with two fully electrically isolated independent measuring input channels for eddy current probe signal access, so short-circuit or open-circuit fault emerging on one measuring loop will not interrupt normal signal acquisition of the other channel. Operators configure vibration pre-alarm threshold and critical shutdown trip value through on-site front panel setting or upper computer configuration tool; once real-time measured vibration value exceeds preset safety limit, built-in relay drive circuit will be triggered to activate local panel alarm lamp and external interlock control circuit for machinery protective shutdown. Integrated comprehensive self-diagnosis function continuously detects probe open-circuit, preamplifier failure, internal board power abnormality and wiring short-circuit issues; corresponding fault indicator on front panel will light up and upload fault codes to rack communication bus once abnormal state is captured. Standard plug-in mechanical structure allows hot-swap replacement inside powered 3300 rack without entire system power cut, effectively shortening field maintenance outage duration of machine protection loop. All real-time vibration data is uploaded via backplane digital bus to upper control system for unified monitoring and fault trend analysis.
4. Electrical and Measurement Technical Parameters
The module is fully compatible with standard Bently 3300XL series eddy current proximity transducer system with regular 200mV/mil standard sensitivity, supporting matched preamplifier remote signal input and long-distance field cable transmission with anti-interference circuit built inside. According to factory coding configuration, default full-scale vibration measuring span follows the parameter defined by suffix 02, and users can adjust partial range parameter via hardware jumper and software configuration within allowable factory setting scope. Overall measurement precision is controlled within ±2% of full calibrated range after original factory precision calibration; internal isolation filtering circuit restrains power frequency interference and high-frequency clutter disturbance generated by adjacent high-power electrical equipment to stabilize signal sampling accuracy. The module obtains working power uniformly from 3300 rack backplane power bus, with internal secondary voltage stabilizing circuit to adapt slight fluctuation of rack input power; two types of output signals are available including passive dry contact relay switch output for interlock and digital bus data output for upper system data collection.
5. Environmental Operating Specifications
The allowable continuous working ambient temperature inside control cabinet ranges from 0°C to +60°C; permissible spare storage temperature spans from -40°C to +85°C under dry non-condensation storage environment, applicable working relative humidity condition is 5%RH~90%RH without surface condensation on circuit board to prevent insulation aging and accidental short-circuit failure. The module can bear regular low-frequency cabinet vibration of 5Hz~1kHz caused by nearby running rotating equipment during normal operation. Installation slot position shall avoid direct heat radiation from heating components and corrosive gas accumulation area inside cabinet to extend service life of internal electronic components; when installing at altitude over 1000 meters, proper reduction of surrounding cabinet ambient temperature is required to ensure long-term stable running performance.
6. Installation and Daily Maintenance Instructions
The monitor adopts standard 3300 rack card slot installation design; align module with internal rack guide rail and push fully into slot until backplane connector is completely plugged in, then fix front panel by built-in locking latch to prevent loose contact caused by cabinet vibration. During regular routine maintenance, maintenance personnel need to periodically check front panel indicator working status, external terminal wiring tightness and cabinet ventilation effect, regularly remove accumulated dust on module surface to avoid overheating induced by poor heat dissipation. When on-site module failure happens, only spare part with identical full part number 26313-02-09-03-05-01-01-01 can be used for direct replacement; cross replacement with modules having inconsistent segmented suffix codes is prohibited without original factory authorization and recalibration. All replacement spare modules complete full functional testing and high-low temperature aging screening before factory delivery to guarantee complete interchangeability during field equipment overhaul.
