2 It is 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, turbo-compressors and system is based around a tq 402 or tq 412 non-contacting transducer and its matching IQS 452 signal conditioner. Together, these form a calibrated proximity 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 ( machine shaft).The active part of the transducer is a coil of wire that is moulded inside the tip of the device, which is made of Torlon (polyamide-imide). The transducer body is made of stainless steel. The target material must, in all cases, be transducer body is available with metric or English thread.
3 The tq 412 version is intended for reverse-mount applications. The tq 402 /412 has an integral coaxial cable, terminated with an AMP-type connector. Various cable lengths (integral and extension) may be ordered. The IQS 452 signal conditioner contains an HF 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 tq 402 /412 transducer can be matched with a single EA 402 extension cable. Optional junction boxes and housings offer mechanical protection of the integral and extension cable proximity system is powered by associated processor modules or a rack power Overall Proximity SystemOPERATIONS ensitivity Using IQS 452 Version 0XX:4 mV/ m (100 mV/mil) Using IQS 452 Version 1 A/ m ( A/mil) Using IQS 452 Version 2XX:8 mV/ m (200 mV/mil) Using IQS 452 Version 3 A/ m ( A/mil)Linear measuring range (typical) Using IQS 452 Version 2XX or IQS 452 Version 3 - mm, corresponding to V to V output using IQS 452 Version mA to mA output using IQS 452 Version 3XX Using IQS 452 Version 0XX or IQS 452 Version 1 - mm, corresponding V to V output using IQS 452 Version mA to mA output using IQS 452 Version 1 XXLinearity:See system performance curvesFrequency response.
