Light curtains that measure at low temperatures
September 2014
Sensors & Transducers
Leuze has engineered its CML 700i light curtains to be used in applications with temperatures down to -30°C. An important bonus is the integrated Profibus interface offered with this high-tech sensor.
The intelligent fastening concept includes an optional plug outlet at the rear, allowing this new light curtain to be easily integrated into most operations. Use of these specially developed devices allows mounting without detection gaps very close to the operational (transport) system.
The plug design facilitates use of the light curtains in a cascaded configuration, which is especially useful if measurement lengths of greater than three metres are required. An integrated alignment mode and visible display of the received signal level simplify and accelerate alignment.
With the extremely rapid response time of 10 microseconds per beam, even very fast processes can be detected and the measurement data recorded. In addition, the ability to detect transparent media increases process reliability in many applications.
Together with integrated interfaces for Profibus, the Leuze CML 700i light curtains also interface with CAN bus, RS-485 and I/O-Link. The data can also be transmitted via analogue outputs, whereby both the control unit as well as the interfaces are housed in the receiver which means that additional devices such as gateways do not need to be mounted.
