High-speed colour detection of fluorescent parts
November 2012
Sensors & Transducers
Conventional luminescence sensors are ineffective when required to perform colour differentiation detection. With the range of Spectro-3-UV sensors from German based Sensor Instruments, there are now sensors that, apart from brightness differentiation (grey scale evaluation), can also detect colour differentiation.
The Spectro-3-UV sensor’s colour memory can store up to 31 different fluorescent objects with colour information provided via five digital outputs. A serial interface is also available.
Teaching of the fluorescent objects can be carried out either under Windows with the included Spectro3-Scope software or using the Teach button that is integrated into the sensor, or through digital input INØ. With its compact M34 housing and sturdy design the sensor is ideally suited for rough industrial use. The 40 kHz scanning and the 30 kHz switching frequency also guarantee a reliable detection and recognition of fast moving fluorescent markings.
