CEMB USA T-NC_16-S - Manual

T-NC/16-S NO CONTACT TRANSDUCER
FUNCTION
Transducer T-NC/16/S is used for performing the following measurements:
DIFFERENTIAL EXPANSION (ex.Turbine), i.e. relative movement between the rotor and the
machine
casing; the measurement is made by mounting the sensor integral with the
machinery casing in the spot corresponding to the thrust block of known characteristics
prepared
on the rotor. The picked up signal should be sent to the CEMB T2 unit for
processing.
AXIAL POSITION, (ex. Turbine Shaft Position with respect to the Thrust Bearing), the
measurement is made by mounting the sensor of each transducer on the machinery casing,
axially facing a block either mounted or obtained
on the rotor close to the thrust
bearing, in order to measure the wear on the bearing. The signals picked up should be
sent of the CEMB T3 units for processing.
ECCENTRICITY, (ex.Turbine Shaft), the measurement is made by mounting the sensor of the
transducer on the machinery casing, radially facing a ring mounted or obtained on the
rotor,
in order to measure the eccentricity of the rotor at low speed; the signal
picked up should be sent of the CEMB T4 unit for processing.
COMPOSITION
The transducer consists of a field-mounted sensor T-NC/16 and converter box T-NC/S
outside the machinery.
