Description

The IQS900 signal conditioner is designed for operation with vibro-meter TQ proximity sensors, that is, non-contact proximity sensors / measurement chains based on the eddy-current principle.
Note: The IQS900 is compatible with different TQ9xx (and TQ4xx sensors) and replaces all previous versions of the IQS45x signal conditioner (PNR 244-45x-000-xxx).

The IQS900 signal conditioner provides a dynamic output signal – current (−15.5 to −20.5 mA) or voltage (−1.6 V to −17.6 V) – suitable for advanced condition monitoring applications that require spectral analysis, for example, machinery analytics and diagnostics. In comparison, the IQS910 signal conditioner provides a slowly-varying output signal (4 to 20 mA current-loop) suitable for machinery protection and/or basic condition monitoring applications based on cost-effective trending of overall levels.

The IQS900 is a configurable and versatile device that generates, converts and processes (high-frequency modulator/demodulator) signals from a TQ proximity sensor into a current or voltage output signal suitable for transmission to the monitoring system. For example, it is factory-configurable for sensitivity and measurement range (transfer function), system length, and optional diagnostic circuitry (with variants defined by ordering option code).

The IQS900 is designed and built for long-term use, and is available in standard versions and in Ex versions certified for use in potentially explosive atmospheres (hazardous areas). Similarly, it is also available with or without diagnostics: versions with diagnostics automatically and remotely indicate the health/status of the measurement chain so you always know when measurements can be trusted. The diagnostics (SIL 2 “by design”) bring enhanced reliability and significant risk reduction, making the IQS900 suitable for use in safety-related applications (functional safety contexts).
