Details
TQ9xx-based proximity measurement chains allow contactless measurement of the relative displacement of moving machine elements, and provide an output signal proportional to the distance between the sensor tip and the target. Accordingly, these measurement chains are ideally suited for measuring the relative vibration and axial position of rotating machine shafts, such as those found in steam, gas and hydraulic turbines, as well as in alternators, turbo-compressors and pumps. A TQ9xx-based proximity measurement chain consists of a TQ9xx proximity sensor, an optional EA90x extension cable and a IQS900 signal conditioner, configured for a particular industrial application. The EA90x extension cable is used to effectively lengthen the front-end, as required. Together, these form a calibrated proximity measurement chain in which each component is interchangeable.
The active part of a TQ9xx proximity sensor is a coil of wire that is moulded inside the tip of the device, made of PPS (polyphenylene sulfide), a high-performance, high-temperature engineering thermoplastic. The sensor body is made of stainless steel. The target material must, in all cases, be metallic. The TQ902 and TQ912 proximity sensors are essentially the same except that the TQ902 is intended for standard-mount and the TQ912 is for reverse-mount applications. Both sensor bodies are available with metric or imperial threads and have an integral coaxial cable terminated with a self-locking miniature coaxial connector. A TQ9xx sensor’s integral cable and the EA90x extension cables are available in various lengths, which can be combined to obtain a particular total system length (TSL) for an application. Optional interconnection protectors (IP172), junction boxes (JB118) and other housings are available for the mechanical and environmental protection of the connection between a TQ9xx sensor’s integral cable and a EA90x extension cable.
Equally important, TQ9xx-based measurement chains using a IQS900 with diagnostics are SIL 2 “by design” so they bring enhanced reliability and significant risk reduction, making them suitable for use in safety-related applications (functional safety contexts). Further, TQ9xx-based measurement chains are form, fit and functionally equivalent replacements that match or better the outstanding performance of TQ4xx-based measurement chains. Each component is interchangeable, so existing TQ4xx-based proximity measurement chains can be quickly and easily replaced or upgraded. For example, a IQS900 signal conditioner without diagnostics is a direct replacement for a IQS45x in most TQ4xx-based measurement chains. Note: A TQ9xx-based measurement chain using a IQS900 configured with a current output and a GSI127 galvanic separation unit, allows transmission over distances up to 1 km – longer than any other solution.
