IQS450 204-450-000-002  proximity measurement system

The system is based around a TQ401 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 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 with metric or imperial thread. The TQ401 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 electro-magnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion.
The TQ401 transducer can be matched with a single EA401 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 such as VM600Mk2/VM600 modules (cards) or VibroSmart® modules, or by another power supply.
