Light curtains that measure at low temperatures

The Leuze CML 700i light curtains can be very flexibly integrated into an operation. The Leuze CML 700i light curtains can be very flexibly integrated into an operation.

Accurate measuring and sensing at low temperatures offers its own challenges. The Leuze CML 700i light curtains have been engineered to be used in applications with temperatures as low as minus 30°C.

An important bonus is that this high-tech sensor offers and integrated Profibus interface. With its intelligent fastening concept including an optional plug outlet at the rear, the Leuze CML 700i light curtains can be very flexibly integrated into an operation. Use of these specially developed light curtains 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, and this is especially useful if measurement lengths of greater than 3m 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 as fast as 10 microseconds per beam, even very fast processes can be reliably detected and the measurement data recorded. In addition, the possibility to reliably detect transparent media increases the process reliability in many cases.

Together with integrated interfaces for Profibus, the Leuze CML 700i light curtains also interface with CAN bus, RS485 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 unit which means that additional devices such as gateways do not need to be mounted. Configuration can be performed directly via the control where all settings remain stored.

This also means that it is possible to exchange a device without reconfiguring it. The full range of Leuze CML light curtains is available from leading sensing solutions specialist company, Countapulse Controls. With more than 35 years of experience in providing appropriate sensors across of wide range of industries in southern Africa, the company also offers a technical hotline to assist customers.
