New laser sensor withstands harsh food processing environments

Micro-Epsilon has launched a new version of its optoNCDT 1402 laser displacement sensor. The sensor is available in eight models with measuring ranges from 5mm up to 600mm. The sensor benefits from an extremely robust, compact and lightweight (83g) design, enabling machine builders and OEMs to easily integrate the sensor into their existing systems. The housing for the SC version is made from V4A steel and so complies with all food industry requirements. This version is resistant to high-pressure jet washing and to aggressive cleaning detergents and disinfection agents, including hydrogen peroxide and other alkaline and chlorine-based cleaning chemicals. In tests at Micro-Epsilon, the 1402SC was subjected to eight hours of hot water jet washing at a pressure of 80-100bar at 85 deg C, as well as an additional dust seal test. Like all optoNCDT 1402 sensors, the SC version has an integral controller that automatically compensates in real time for difficult-to-measure surfaces such as shiny metal, gloss paint finishes and black rubber. This real time surface compensation (RTSC) feature enables OEMs and machine builders to more accurately measure a variety of object parameters, including thickness, roundness, position, deflection, tilt, displacement and vibration. The sensor housing measures just 65mm (L) x 50mm (H) x 20mm (W). This compact design and integral controller enable rapid mounting and installation, even in restricted spaces on machines or next to production lines. With no separate controller to mount, machine builders and systems integrators will reduce wiring costs and free up space in their control cabinets. The optoNCDT 1402SC offers an analogue current/voltage output and an RS422 digital interface. Other options include high flex cables for use with drag chain and robots. Configuration software and a calibration certificate are supplied as standard.
