T-NC Proximity Transducer
Proximity Transducer
The CEMB T-NC Proximity Transducer detect the displacement
of a target facing to the sensor. The different dimensions of the sensor allow
its application for the detection of different measuring ranges.
The
principle of operation is based on the generation of an high frequency field,
radiated by the probe, which induces an eddy current in the target facing to
the probe itself. The intensity of this eddy current depends directly on the
probe air gap and it is converted into an electrical signal processed by the
converter.
The eddy
current transducer is used for no-contact measurement of displacement and
expansion of rotating machines.
The
probe structural features allow its installation in a particularly heavy
environment, with the presence of steam, oil and aggressive agents (typically
on steam turbines, gas turbines, compressors, etc.).
These
transducers are composed of a ST-NC/16, ST-NC/20 or ST-NC/30 probe and a T-NC
converter contained in a die-cast aluminium housing, complete with a connector
(according to MIL standards) for the connection of the transducer to the
acquisition system
