IQS900 204-900-000-011 signal conditioner
Description:
The IQS900 signal conditioner contains a high-frequency modulator/demodulator that supplies a driving signal to a TQ9xx sensor. This generates an electromagnetic field in the tip of the sensor, which generates eddy-currents in the metallic target. When the target moves, the eddy-currents change, which causes a change in the electrical characteristics of the TQ9xx that the signal conditioner converts into a signal that is proportional to the distance to the target.
The IQS900’s output is an analogue signal consisting of a dynamic component (AC) that corresponds to the measured vibration (displacement) and a quasi-static component (DC) that corresponds to the measured gap. The output can be configured as a current or a voltage signal, suitable for transmission to a monitoring system via current (2-wire) or voltage (3-wire) transmission cables, respectively.
For an IQS900 signal conditioner with optional diagnostics, the quasi-static DC component also functions as a diagnostic indicator. That is, the IQS900’s diagnostic circuitry continuously checks the integrity of the measurement chain and will drive the measurement/diagnostic component (DC) outside of its normal operating range to indicate a problem with the sensor, the cabling and/or the signal conditioner itself.
For test purposes, the IQS900 includes a “raw” voltage output signal and a test input signal that allow the measurement chain/system operation to be tested in situ, thereby simplifying commissioning and troubleshooting.
