EA403 913-403-000-012 extension cable-Colletplc

Description:

This proximity system allows contactless
measurement of the relative displacement of moving
machine elements. It is particularly suitable for
measuring the 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 TQ 403 non-contact
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, 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 TQ 403 has an integral coaxial cable,
terminated with a self-locking miniature coaxial
connector. Various cable lengths (integral and
extension) can be ordered.
The IQS 450 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 TQ 403 transducer can be matched with a single
EA 403 extension cable to effectively lengthen the
front-end. 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.
The proximity system can be powered by associated
signal processing modules (for example, VM600
cards) or a rack power supply.

SPECIFICATIONS:

System calibration
Calibration temperature : +23 °C ± 5 °C
Target material : VCL 140 steel (1.7225)
Note: If special calibration is required, please define the alloy precisely or supply a sample of alloy (min. Ø 60 mm /
1 cm thick) according to Meggitt Sensing Systems’ drawing number PZ 7009/1.
Total system length
The total system length (TSL) is the sum of the length of the TQ 4xx transducer’s integral cable and the length of the
EA 40x extension cable. The supported TSLs can be obtained from different combinations of cables.
Total system lengths
• 5 m : 1.0 m integral cable + 4.0 m extension cable
5.0 m integral cable with no extension cable
• 10 m : 1.0 m integral cable + 9.0 m extension cable
5.0 m integral cable + 5.0 m extension cable
10.0 m integral cable with no extension cable
The combination of cables selected for a particular total system length depends on the application. For example, to
obtain the optimum location for the separation between the integral and extension cables or to eliminate the
requirement for an extension cable.
Total system length trimming
Due to the characteristics of the coaxial cable, an "electrical trimming" of the nominal length of extension cables is
necessary to optimize the system performance and the transducer interchangeability.
TSL for a 5 m measuring chain : 4.4 m minimum
TSL for a 10 m measuring chain : 8.8 m minimum
