CEMB USA T-NC_30-S User Manual

T-nc/30-s no contact transducer

T-NC/30-S NO CONTACT TRANSDUCER

FUNCTION

Transducer T-NC/30/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/30 and converter box T-NC/S

outside the machinery.
