Series FTI 10

nnnn

Special features

nnnn

• long service to non-contact

nnnn

measuring system

nnnn

• excellent linearity up to

nnnn

± 0.1%

nnnn

• reliable signal transmission

nnnn

through standardized current

nnnn

output

nnnn

• robust due to

nnnn

completely encapsulated

nnnn

housing

nnnn

• temperature-resistant

nnnn

precision due to supplemen-

nnnn

tary regulating winding

nnnn

The inductive precision sensor

nnnn

FTI is used to transform short

nnnn

linear travel paths into ana-

nnnn

logue electrical signals using a

nnnn

differential transformer with a

nnnn

movable core.

nnnn

The core is located on a gau-

nnnn

ging pin which is pressed

nnnn

against the measured object

nnnn

by an integrated spring. The

nnnn

sensor is supplied with direct

nnnn

voltage from which an integra-

nnnn

ted oscillator generates an

nnnn

alternating voltage to feed the

nnnn

differential transformer.

nnnn

The secondary transformer

nnnn

voltages are rectified in a built-

nnnn

in demodulator. The oscillator

nnnn

and demodulator are de-

nnnn

signed using hybrid technolo-

nnnn

gy. The output current is

nnnn

strictly proportional to the

nnnn

displacement of the core and

nnnn

therefore to the measured

nnnn

path.

nnnn

The non-contact sensors are

nnnn

virtually maintenance- and

nnnn

wear-free and boast a perfect

nnnn

reproducibility, resolution and

nnnn

linearity. The exchange can

nnnn

take place without recalibra-

nnnn

tion. Magnetic fields have no

nnnn

effect on the measured signal.

nnnn

The precision sensor is avail-

nnnn

able in protection class IP50

nnnn

and IP67 and due to its com-

nnnn

pletely encapsulated housing

nnnn

and temperature compensa-

nnnn

ting properties of its control-

nnnn

loop coil, it can be used under

nnnn

rough environmental operating

nnnn

conditions.
