The system is based around a TQ423 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 TQ423 is specially designed for high-pressure applications, with the transducer tip withstanding pressures of up to 100 bar. This makes them particularly suitable for measuring relative displacement or vibration on submerged pumps and various types of hydraulic turbines (for example, Kaplan and Francis). This transducer is also suitable for use when the region of the output of the transducer is cluttered.
The active part of the transducer is a coil of wire that is moulded inside the tip of the device, made of PEEK (polyetheretherketone). 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 TQ423 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.
