IQS452 204-452-000-221 Signal Conditioner

 

 

IQS452 204-452-000-221 is a Signal Conditioner of the Proximity Measurement System, which is used in conjunction with TQ402 or TQ412 non-contact eddy current probes and EA402 Extension Cable to form a complete shaft vibration and shaft displacement measurement system. The entire measurement chain adopts the eddy current (Eddy Current) non-contact measurement principle, capable of continuously detecting key mechanical state parameters such as relative vibration, axial displacement, and gap changes of the rotating machinery shaft.

During the operation of large rotating equipment, problems such as bearing wear, shaft misalignment, thermal expansion, rotor imbalance, and coupling eccentricity can cause changes in the shaft's center position. The IQS452 processes the distance-change signals collected by the probe, enabling the monitoring system to continuously monitor the equipment's operating status and providing continuous data support for predictive maintenance, condition monitoring, and equipment protection.

Different IQS452 versions provide different sensitivity configurations to meet various machine protection and shaft vibration monitoring requirements.

The IQS452 Signal Conditioner is available in multiple versions with different output modes, sensitivities, measuring ranges, and hazardous area approvals. The 204-452-000-221 model belongs to the IQS452 product family. Before ordering, users should verify the required measuring range, output configuration, total system length, and certification requirements to ensure compatibility with the existing proximity measurement system.

--Utilize the non-contact electro-vortex flow measurement principle

The IQS452 is based on the mature Eddy Current technology. It drives the TQ402 or TQ412 probe with high-frequency alternating signals, creating an electromagnetic field on the surface of the metal target. When the distance between the shaft and the probe changes, the eddy currents generated on the metal surface also change. The IQS452 converts this change into a linear voltage or current output, enabling continuous distance measurement.
Since the entire measurement process does not require mechanical contact, it will not cause wear on the measured shaft or affect the normal operation of the equipment.

--Provide voltage output or current output

The IQS452 supports two standard output methods:
-Voltage Output (3-wire system)
Suitable for most vibration monitoring systems.
Output range:
Minimum Gap: -1.6 V
Maximum Gap: -17.6 V
