Operating principle
The operation of the Turck LTX sensors is based on the magnetostrictive principle. A so-called
“waveguide” is located in the measuring probe of the linear position sensor. If a current signal
generated on the waveguide hits the magnetic field of the positioning element applied from
outside, this produces a mechanical feedback in the waveguide. This feedback is evaluated in
the sensor head and output as position information.
4.4
Functions and operating modes
The devices feature a current or voltage output. The device output provides a current or
voltage signal proportional to the position of the positioning element (see output characterist-
ics).

4.4.1
Automatic signal control
The device is automatically adjusted to the signal strength of the positioning element as soon
as the sensor is supplied with power. The automatic signal control fully compensates for any
tolerances.
4.4.2
Current output
LTX…LI… devices feature a current output, which outputs a current signal in line with the posi-
tion of the positioning element (e.g. 4…20 mA, depending on design). The measuring range is
adjustable.
4.4.3
Voltage output
LTX…LU… devices feature a voltage output, which outputs a voltage signal in line with the
position of the positioning element (e.g. 0…10 V, depending on design). The measuring range
is adjustable.
