Triangulation Sensor

Suitable for measuring the position displacement of red-hot glowing metals and translucent targets, Micro-Epsilon’s optoNCDT 1700BL series of blue laser sensors operate on the laser triangulation measuring principle. The laser diode projects a visible point of light onto the surface of the target object. The light reflected from this point is then projected onto a CCD array. If the target changes position with respect to the sensor, the movement of the reflected light is projected on the CCD array and analyzed to output the exact position of the target. The measurements are processed digitally in the integral controller. The data is output via analogue and digital interface such as RS-422 or USB. Using the company’s software algorithms, the sensor’s measurement rate can be slowed down for difficult surfaces. This means that it can compensate in real time and the laser light’s exposure time on the CCD can be optimized for the surface of the object to be measured, resulting in higher measurement accuracy. The sensors are suitable for red glowing metals up to 1,600 °C and for silicon up to 1,150 °C. The series includes six sensor models with measuring ranges from 20 up to 1,000 mm. The sensor’s measuring range can be adjusted up to 2.5 kHz and can be used as a freely programmable limit switch. Maximum linearity is 16µm. Without averaging, the maximum resolution at 2.5 kHz is 1.5 µm. Highly flexible cables for use with robots can be provided. A calibration certificate is included as standard.
