111-402-000-012 TQ402 proximity transducers

DESCEIPTION:

This proximity system allows contactless measurement
of the relative displacement of moving machine
elements. 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 pumps.
The system is based around a TQ 402 or TQ 412 noncontacting
transducer and an IQS 450 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
(e.g. 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 metallic.
The transducer body is available with metric or English
thread. The TQ 412 version is intended for reversemount
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 450 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 extrusion.
The 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 connectors.
The proximity system is powered by associated
processor modules or a rack power supply.
