TQ403 111-403-000-013 PROXIMITY TRANSDUCER
Description:
The TQ403, EA403 and IQS450 form a proximity measurement system. This proximity measurement system allows contactless easurement of the relative displacement of moving machine elements.
TQ403 based proximity measurement systems are particularly suitable 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, turbocompressors and pumps.
The system is based around a TQ403 non-contact sensor and an IQS450 signal conditioner. Together, these form a calibrated proximity
measurement system in which each component is interchangeable. The system outputs a voltage or a current proportional to the distance between the transducer tip and the target, such as a machine shaft.
The active part of the transducer is a coil of wire that is moulded inside the tip of the device, made of Torlon® (polyamide-imide). The transducer body is made of stainless steel. The target material must, in all cases, be metallic.
The transducer body is available only with metric thread. The TQ403 has an integral coaxial cable, terminated with a self-locking miniature coaxial connector. Various cable lengths (integral and extension) can be ordered.
The IQS450 signal conditioner contains a highfrequency modulator/demodulator that supplies a driving signal to the transducer. This generates the necessary electromagnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion.
The TQ403 transducer can be matched with a single EA403 extension cable to effectively lengthen the front-end. Optional housings,
junction boxes and interconnection protectors are available for the mechanical and environmental protection of the connection
between the integral and extension cables.
TQ4xx-based proximity measurement systems can be powered by associated machinery monitoring systems modules, or by another
power supply.
