IQS452 204-452-000-011

Product Details

Vibro-meter IQS452 204-452-000-011 is a high-performance signal conditioner specifically designed for use with the TQ 422 and TQ 432 series of pressure-resistant proximity sensors. The Signal Conditioner is the core component of a uniform, interchangeable proximity measurement system used for monitoring relative displacement and vibration in harsh industrial environments. This model configuration is suitable for A total system length of 5 meters and adopts a two-wire connection, providing a current output compatible with 4-20 mA (with a sensitivity of 1.25 µA/µm). The main function of IQS452 204-452-000-011 is to power the eddy current sensor, demodulate high-frequency signals, and convert gap measurement values into robust current signals that comply with industry standards, which are not disturbed by electrical noise during long-distance transmission.

Product Features

The current loop output adopts a two-wire system, featuring excellent resistance to electromagnetic interference and signal attenuation, making it highly suitable for long-distance cable connections between sensors and monitoring systems.

IQS452 204-452-000-011 Each component (sensor, cable, signal conditioner) in the Vibra-meter proximity vibration measurement system is interchangeable and does not require separate calibration, thus simplifying maintenance and spare parts management.

The high-frequency (HF) modulator/demodulator generates the precise drive signal required by the sensor and precisely converts the eddy current effect into a proportional DC signal.

The robust and durable industrial design features a durable aluminum casing, providing mechanical protection and facilitating heat dissipation, ensuring reliable operation even in harsh factory environments.

The wide frequency response can capture slowly changing relative positions (for example, axial runout) as well as high-frequency vibration events up to 20 kHz.

The output terminal is equipped with short-circuit protection function, which enhances the durability of the system.
