Uses high-frequency modulation and demodulation to condition the proximity-transducer signal.
Technical Summary
IQS450 is a Vibro-Meter signal conditioner for TQ4xx-based proximity measurement systems. It supplies the transducer excitation and converts the eddy-current measurement into an ordering-code-specific voltage or current output.
IQS450 is a family identity rather than a complete ordering code. Sensor type, extension cable, system length, sensitivity, output form and certification options must be matched as one documented system.

Features
Supports voltage-output and current-output configurations when ordered as the corresponding complete system.
Works in non-contact relative-displacement and shaft-position measurement arrangements.
Keeps sensor, cable and conditioner selection inside one calibrated proximity-system definition.
Compatibility
- Provide the full IQS450 material number; the family name alone does not define sensitivity or output type.
- Match the exact TQ4xx sensor, EA extension cable when used, total system length and target material.
- Confirm the receiving monitor input expects the ordered voltage or current signal.
- Retain any hazardous-area approval identity and system certificate associated with the installed configuration.
Replacement
- Record the static gap, sensor model, cable path, total electrical length and conditioner label before removal.
- Replace the conditioner only with an approved configuration that matches the installed proximity system.
- After installation, verify gap voltage or current, linear response, polarity and monitor-channel scaling.
- Do not publish or order from the standalone IQS450 family name when the complete material number is available.
FAQ
Is IQS450 a complete orderable model by itself?
It identifies the signal-conditioner family, but the full material and option code is needed to define the electrical output and matched proximity system.
Can any TQ4xx sensor be connected to an IQS450?
No. Use the sensor, extension cable and conditioner combination listed for the documented TQ4xx system and total length.
What evidence should accompany an IQS450 quotation?
Send every label, sensor and extension-cable number, total system length, output type, sensitivity, monitor input and required quantity.
Can an IQS450 voltage-output unit replace a current-output version?
Not without an engineering review because the receiving channel, scaling, wiring and ordered proximity-system option are different.
What commissioning checks matter after changing IQS450?
Verify the mechanical gap, conditioned output, linear response over the approved movement, channel scaling and alarm behavior.
