Position Transducer
with return spring,
non-contacting
Series FTI 10

The inductive precision sensor
FTI is used to transform short
linear travel paths into analogue
electrical signals using a
differential transformer with a
movable core.
The core is located on a gauging
pin which is pressed
against the measured object
by an integrated spring. The
sensor is supplied with direct
voltage from which an integrated
oscillator generates an
alternating voltage to feed the
differential transformer.
The secondary transformer
voltages are rectified in a builtin
demodulator. The oscillator
and demodulator are designed
using hybrid technology.
The output current is
strictly proportional to the
displacement of the core and
therefore to the measured
path.
The non-contact sensors are
virtually maintenance- and
wear-free and boast a perfect
reproducibility, resolution and
linearity. The exchange can
take place without recalibration.
Magnetic fields have no
effect on the measured signal.

Special features
? long service to non-contact
measuring system
? excellent linearity up to
± 0.1%
? reliable signal transmission
through standardized current
output
? robust due to
completely encapsulated
housing
? temperature-resistant
precision due to supplementary
regulating winding
