3 For your Safety

The product is designed in accordance with the latest standards. However, residual risks still

exist. Observe the following warnings and safety information to prevent personal injury or

damage to property. Turck accepts no liability for damage caused by failure to observe these

warning and safety instructions.

3.1 Intended use

The devices are intended solely for use in industrial areas.

The magnetostrictive linear position sensors are used for contactless and wear-free linear posi-

tion detection. The devices are suitable for use in hydraulic cylinders. By adding float magnets

(available as an option), the devices can also be used for level measurement. The measuring

range is adjustable.

The devices must be used only as described in these instructions. Any other use is not in accor-

dance with the intended use. Turck accepts no liability for any resulting damage.

3.2 General safety information

■The devices are not safety components and must not be used for personal or property

protection.

■The device must be mounted, installed, operated, parameterized and maintained only by

trained and qualified personnel.

■The device complies exclusively with the EMC requirements for industrial applications and is

not suitable for use in residential areas.

Product Description

4 Product Description

The linear position sensors with an analog output are available with a current or voltage output.

An M12 connector is available for the connection. All devices feature a rod design with IP68

protection. The devices operate without contact, which requires the use of a positioning ele-

ment approved by Turck (see Accessories). The measuring range is adjustable.

The devices operate on an absolute basis; power outages do not necessitate renewed zero off-

set adjustment or recalibration. All position values are determined as absolute values; reference

runs after a voltage drop are unnecessary.

4.3 Operating principle

Turck LTX sensors utilize the magnetostrictive principle. A "waveguide" is located in the measur-

ing probe of the linear position sensor. If a current signal generated at the waveguide encoun-

ters the externally applied magnetic field of the positioning element, mechanical feedback is

produced in the waveguide. This feedback is evaluated in the sensor head and output as posi-

tion 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 characteristics).

I [mA]

U [V]

Fig. 2: Output characteristics – devices with

4…20 mA current output

Fig. 3: Output characteristics – devices with

0…10V voltage output

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.

4.4.4 Preferred types LTX…M-F10-LI0-X3-H1151 – Measuring range

Preferred types LTX…M-F10-LI0-X3-H1151 are available with the following measuring lengths

as standard:

Measuring range congured

100…500mm in 25mm increments

500…2000mm in 50mm increments

2000…7600mm in 500mm increments
