The sensors are intended for non-contact measuring and checking of position, displacement, dimensions, surface ' profile,deformation, vibrations, sorting and sensing of technological objects as well as for measuring levels of liquid and bulk materials.

The series includes a series of sensors with the measurement range, from 2 to 2500 mm and the base distance from 10 to 420 mm. Custom-ordered configurations are possible with parameters different from those shown below.
ZLDS100 — universal sensors with 2 to 1250 mm operating ranges.
ZLDS100/HS — high speed sensors;
ZLDS100RD — specialized laser sensors for pavement profile and texture measurement;
ZLDS101 — large-base and long range sensors;
ZLDS102 — compact sensors;
ZLDS103 — super compact sensors.

ZLDS11X sensors are optical displacement measuring devices for non contact precision measurement of distance or thickness, width and difference .

The series includes seven lines of models:
ZLDS112 - small size sensors
ZLDS113 - Small Measurement Ranges sensors
ZLDS114 - Offering 10 Different Measuring Ranges
ZLDS115 - Longer Measurement Ranges sensors

The ZLDS11X is a compact unit in which optics, sensor, and signal processing electronics are all integrated. The distance to an object is detected by means of the triangulation principle. A focused laser beam forms a spot on the measuring object. The image of the spot is reflected onto a position detector, a CCD camera, and the ZLDS11X converts this position into the distance to the object by advanced mathematical procedures.

The output signal is provided in 3 different manners. One digital output, an RS232 or RS422 serial output, provides the distance to the object with a frequency of 1000, 2000, 5000 or 10000 Hz acording to Model. At the same time two analog outputs deliver the measured distance, one as a 1 - 9 V DC signal and the other as a 4 - 20 mA current loop.
