This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively insensitive to ambient light, it uses a ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

Most beam detector systems consist of a transmitter, receiver and control unit. The transmitter projects the beam, the receiver at the ‘end’ of the beam measures its intensity with a photosensitive ...

FIREX exhibitor FFE is launching an ATEX-certified, explosion-proof optical beam smoke detector – the Fireray 3000 Exd – in the Middle East and Asia. The product: Designed to protect wide areas ...

The BBA-4000 is a solar powered wireless infrared break beam system that is simple to install and requires no wiring. The break beam sensors are powered by lithium ion batteries that are recharged ...

Experimental setup showing the two ultrafast silicon detectors used to determine the energy of clinical proton beams. (Courtesy: Anna Vignati) Beam energy is a key parameter in particle therapy, ...

The recently opened new Concourse A of Dubai International Airport has had 265 Fireray end to end infrared beam smoke detectors installed as part of its fire protection system. There are now a total ...
