LTE Position System
The LTE is a in-line position sensor with an innovative magnetostrictive solution and no electric contact. The absence of an electric contact on the slide eliminates the problem of wear and guarantees a virtually unlimited life. The position sensor is fixed in one of the sensor slots in the actuator liner by means of two screws. Actuators to which the position sensor is applied are standard and require no adaptation, they just have to be the magnetic version. The position sensor automatically detects the position of the magnets inside the cylinder. The LTE is applied to ISO 15552 type A cylinders with the same stroke and the measuring length.
For longer strokes please contact our sales department.

LTL POSITION SENSOR
Positioniersystem LTL
Non-contact displacement measuring system

Non-contact displacement measuring systems
LTL POSITION SENSOR
The LTL position sensor uses an array of Hall sensors to measure positions without contact, thanks to the presence of a magnet inside the cylinder. It uses a smart algorithm to adapt dynamically to the magnets during operation, so that the output signal is always linear and reproducible. This technology allows the position sensor to adapt dynamically to changes in the intensity of the magnetic field connected with ageing of the magnet and the different operating temperatures. A magnetic field intensity of between 2 and 15 mT is required for correct moperation.
The LTL can be set by means of a TEACH-PAD capacitive button that allows rapid actuation of the position sensor and adaptation to the user’s requirements. Just press slightly with the fingers to:
• select an output current (4-20 mA) or output voltage (0-10 V);
• establish the desired measuring range;
• reset the position sensor to the factory setting.
The button is designed to prevent unintentional changes to the parameters.
The position sensor is out of the measuring range when:
• the yellow light is off; and
• the voltage signal is 11V (range 0-10V) or the current 3 mA (range 4-20 mA).
LED1 (operating light) comes on when the piston is in the measuring range:
• yellow on - optimal signal power;
• yellow on and red flashing - signal power not optimal.
LED2 tells you which analogue output is active:
• green – voltage analogue output;
• blue – current analogue output.
The position sensor is secured by means of brackets near one of the actuator T-slots.
The LTL position sensor is applied to ISO 15552 type A cylinders, and electric cylinders serie ELEKTRO ISO 15552. For longer strokes please contact our sales department.

Non-contact displacement measuring systems
LTS Position Sensor
The LTS is a magnetic position sensor for measuring linear strokes of actuators.
The position of the piston is measured without contact and given via a configurable analogue output signal, as voltage or current.
The body of the LTS is very compact, so it can be used in applications where limited space is available. This position sensor can measure the strokes of various families of actuators up to 256 mm.
Correct operation requires a magnetic field strength of between 4 and 30 mT.
The measurement range can be regulated accurately using the Teach-in button (zero point and end point).
Teach-in can be performed regardless of the polarity of the magnetic field and the position of the sensor.
The yellow ON light comes on when the piston is in measuring range.
The position sensor is out of the measuring range when:
• the yellow light is off; and
• the voltage signal is 11V (range 0-10V) or the current 3 mA (range 4-20 mA)
