T5-LVDT/25-24 TRANSDUCER
FUNCTION
The transducer T5-LVDT/25/24 is used for performing the measurement of Absolute
Displacement, the measurement is made by means of a position transducer system based on
a linear variable differential transformer (LVDT) by mounting the transducer body on a
fixed point and positioned so that the sensor tip of transducer T5-LVDT/25 presses
permanently against one end of the movable part of the machine casing.
The as picked-up signal is sent to the adapter part AD1-BOX (signal converter situated
downstream of the transducer), which makes it suitable for processing by one CEMB T5
unit.
PRINCIPLE OF OPERATION
A rod in close contact with the movable part to be checked is strictly integral with a
magnetic core moving within a fixed coil inside the transducer sensor body. The coil
has one primary winding and two secondary windings connected in opposing phase; the
output signal (secondary winding) is proportional to the mechanical displacement of the
core and should, therefore, be sent to an adapter module (AD1) which makes it suitable
for subsequent processing by CEMB instruments, of the “T” series.
