Information

Overview Manuals Common Applications Product Precautions

The IQS450 S3960 204-450-000-002-A1-B21-H5-I0 functions as the high-performance signal conditioner component calibrated for TQ402 and TQ412 proximity measurement systems.

Non-contact measurement system based on eddy-current principle
Ex certified versions for use in hazardous areas (potentially explosive atmospheres)
Voltage or current output with protection against short circuits

Together with a compatible probe, it forms a calibrated proximity measurement system in which each component is interchangeable. The system outputs a voltage or current proportional to the distance between the transducer tip and the target, such as a machine shaft. The target material must, in all cases, be metallic. The IQS450 signal conditioner contains a high-frequency modulator/demodulator that supplies a driving signal to the transducer. This generates the necessary electro-magnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion.

This specific model incorporates the B21 linear calibration for standard proximity transducers and the H5 internal tuning circuitry, meaning it is impedance-matched exclusively for a 5-meter total system cable length (including both the probe integral cable and an EA402 extension cable). TQ4xx-based proximity measurement systems can be powered by associated machinery monitoring systems such as VM600Mk2/VM600 modules (cards), VibroSmart® modules, or by another compliant power supply.

Thermal Power Generation

Real-time monitoring of axial displacement and shaft vibration for large supercritical steam turbine-generator units to prevent rotor-to-stator rubbing under high temperature and pressure.

Hydroelectric Power Generation

Monitoring hydraulic unbalance vibration of main shafts and oil-film clearances of guide bearings in large hydro-generator units to sustain structural stability.

Nuclear Power Generation

Online monitoring of shaft oil-film vibration and runout for million-kilowatt class high/low-pressure steam turbines in conventional islands to prevent mechanical fatigue fractures.

Petroleum Refining

Measurement of axial displacement and relative shaft vibration for core rich-gas compressor trains in fluid catalytic cracking units (FCCU) to trigger over-limit emergency shutdown interlocks.

Coal Chemical Industry

High-frequency vibration measurement for shafts of high-pressure air and oxygen compressors in large air separation units (ASU) to protect high-speed impellers against unbalance damage.

Iron & Steel & Metallurgy

Shaft orbit and axial displacement monitoring for large dynamic equipment such as blast furnace blowers and converter gas recovery units to safeguard continuous air supply.

Strictly maintain the cumulative length of the measurement chain (probe integral cable plus extension cable) at 5 meters, as any unauthorized cutting or lengthening will introduce severe measurement errors due to impedance mismatch. The coaxial connectors (self-locking miniature coaxial connectors) must be enclosed in insulating sleeves on site, never allow their metal shells to touch the machine casing or cable trays to prevent ground loop noise from disrupting the weak vibration signals.

The module requires a standard negative DC voltage (-24V DC) supply, so polarity must be double-checked during wiring. Additionally, ensure the aluminum enclosure is firmly grounded during field installation to maintain optimal electromagnetic shielding performance.
