Application & Operating Context

Measurement Application

Shaft Position & Vibration Monitoring

Used within Bently Nevada 7200 proximity transducer systems to monitor the distance between a probe tip and a conductive machine target. Typical machinery includes turbines, compressors, pumps, motors and generators.

Maintenance Scenario

Signal Loss & Unstable Readings

Abnormal output, a failed monitoring channel or a NOTOK condition may prompt replacement checks. An unresolved sensor-channel fault can reduce shaft-condition visibility and delay the detection of machinery problems, increasing unplanned downtime risk.

Technical Specifications

KEY SELECTION DATA
CONFIGURATION / ELECTRICAL / MEASUREMENT
COMBINED SYSTEM LENGTH 9 m 29.6 ft
NOMINAL SCALE FACTOR 200 mV/mil
METRIC SCALE FACTOR 7.87 V/mm
FREQUENCY RESPONSE 0–10 kHz · 7200 family
Configuration: The -04 suffix identifies a 9 m combined probe and extension-cable system length. Scale factor and frequency response are 7200 system-family reference values, not separate dimensions or standalone specifications of the housing.
7200 Series 5 mm / 8 mm — Additional Reference Specifications

Series-level operating and performance reference values for the 7200 5 mm / 8 mm proximity system. Actual performance depends on the matched probe, extension cable, Proximitor and installation arrangement.

AVERAGE SCALE FACTOR · TYPICAL 7.87 ± 0.21 V/mm 200 ± 5.4 mV/mil · 90% performance
AVERAGE SCALE FACTOR · WORST CASE 7.87 ± 0.39 V/mm 200 ± 10 mV/mil · 99.7% performance
INCREMENTAL SCALE FACTOR · TYPICAL 7.87 ± 0.51 V/mm 200 ± 13 mV/mil · 90% performance
INCREMENTAL SCALE FACTOR · WORST CASE 7.87 ± 0.75 V/mm 200 ± 19 mV/mil · 99.7% performance
DEVIATION FROM STRAIGHT LINE · TYPICAL < ±0.038 mm < 1.5 mil · 90% performance
DEVIATION FROM STRAIGHT LINE · WORST CASE < ±0.058 mm < 2.3 mil · 99.7% performance
DEVIATION FROM BEST STRAIGHT LINE · TYPICAL < ±0.046 mm < 1.8 mil · 90% performance
DEVIATION FROM BEST STRAIGHT LINE · WORST CASE < ±0.058 mm < 2.3 mil · 99.7% performance
GAP AT -3.0 V 0.508 ± 0.254 mm 20 ± 10 mil
PROXIMITOR SUPPLY VOLTAGE -17.5 to -26 Vdc With barriers: -23 to -26 Vdc
Additional electrical characteristics: Maximum current draw 12 mA with a 10 kΩ load; output resistance 50 Ω; calibrated output load 10 kΩ resistive; output noise below 10 mV peak-to-peak under the stated test load. A short or open circuit in the probe or extension cable drives the output to within 1.0 V of common.

System Matching & Installation

The 7200 measurement arrangement uses a probe, extension cable and Proximitor as a matched transducer system.

Before replacement, verify the installed probe, extension cable electrical length, connector arrangement and monitoring-channel requirements.

Check the probe-to-target gap and target material during commissioning. Follow the applicable installation procedure for the complete transducer system.

Diagnostic Checkpoints

NOTOK indication Inspect the field wiring, transducer condition, power source and probe-to-target clearance.
No output signal Check supply voltage, possible wiring shorts, terminal connections and Proximitor condition.
Unstable readings Inspect connectors, cable condition, probe installation and target surface.

Frequently Asked Questions

1. What does the -04 ordering suffix specify?

It identifies a combined probe and extension-cable system length of 9 metres (29.6 feet).

2. Does the 9 m designation refer to the Proximitor housing size?

No. It refers to the combined electrical system length from the probe arrangement through the extension cable to the Proximitor.

3. What should be verified before replacing this component?

Check the existing part number, installed probe, cable electrical length, connectors and monitoring-channel configuration.

4. What machinery can use the 7200 proximity measurement system?

Typical applications include shaft position and vibration monitoring on turbines, compressors, pumps, motors and generators.

5. What information helps identify a suitable replacement?

A clear nameplate photograph, existing cable and probe details, system configuration and machine model help reduce ordering mismatches.
