Supports voltage-output or current-output measurement chains selected by the sensitivity code.
Product Overview
204-450-000-002 is the manufacturer base ordering number for the IQS450 signal conditioner in Vibro-Meter proximity measurement systems. The conditioner supplies the high-frequency drive to the sensor and converts the response into an output proportional to gap.
The base number does not complete the configuration. Environment, sensitivity and range, total system length, and installation selections must be read from the full order code or the installed label before replacement.
Performance
Covers 2 mm or 4 mm measuring ranges with a DC to 20 kHz system response.
Allows 1 m, 5 m or 10 m total sensor-plus-extension-cable lengths.
Uses interchangeable system components when the same documented configuration is maintained.

System Integration
- Read the complete installed order code; do not derive environment, output type, range or cable length from 204-450-000-002 alone.
- Match the sensor, extension cable and IQS450 fields so total electrical length remains 1 m, 5 m or 10 m as ordered.
- Preserve negative supply polarity, COM and output terminal assignment.
- For Ex versions, confirm certificates, barriers and enclosure conditions for the exact A2 or A3 selection.
- Set the mechanical gap and verify the output against the selected voltage or current transfer function.
Applications
- Relative shaft vibration and gap or axial-position measurement.
- Machinery protection and condition monitoring on turbines, generators, compressors and pumps.
- Maintenance of VM600Mk2, VM600 or VibroSmart measurement chains using the configured IQS450 family.
FAQ
Why is 204-450-000-002 not enough to select a finished IQS450?
It is the base ordering number; the environment, sensitivity/range, total system length and mounting fields determine the supplied execution.
How can voltage and current versions of 204-450-000-002 be distinguished?
Use the full B option: B21/B23 are voltage sensitivities, while B22/B24 are current sensitivities.
What happens if the cable length is changed around 204-450-000-002?
The proximity system is electrically trimmed for its ordered total length, so an unmatched sensor or extension cable can shift sensitivity and linearity.
What should be measured before replacing 204-450-000-002?
Record full order codes, supply, static gap output, sensor and extension lengths, target material, monitoring-channel scaling and hazardous-area documents.
How should 204-450-000-002 be functionally accepted?
Confirm supply polarity, static gap, linear response across the useful movement, dynamic signal quality and protection-channel alarm behavior.
