204-900-000-011 IQS900 A5-B23-C1-H05-I1 Signal Conditioner
Description:
IQS900 204-900-000-011 is designed for the proximity measurement chains. Act as a signal conditioner, IQS900 base on the eddy current principle, fitted with a high-frequency modulator/demodulator to drive TQ9xx sensors, such as T902, TQ912. It produces an electromagnetic field at the sensor tip, inducing eddy currents in the metallic target. Target movement changes these eddy currents and modifies the electrical properties of the TQ9xx sensor. IQS900 converts this variation into an output signal proportional to the sensor-target gap.

Major Features:
▪ Standare versions and Ex versions
▪ Diagnostic capability
▪ Suitable for use in the potentially explosive atmosphhere
▪ Wide frequency range: DC to 20000 Hz
▪ Current or voltage output signal
▪ Fully compliant with API 670 5th edition
▪ “Raw” output and “Test” input signals for in-site test support
▪ DIN-rail mounting and removable screw-terminal connectors

Applications:
▪ Steam, gas and hydraulic turbines
▪ Generators
▪ Turbo-compressors
▪ Pumps
