TWN-LUX - Light Sensor:
Product Specifications:
Description:
The TWN-LUX incorporates a silicon photodiode light sensor, in a hermetical sealed case, especially designed for high precision linear applications. The sensor has a flat glass window with a built in colour correction filter, giving an approximation to the spectral response in the human eye. As an aid in adjustment an LED is mounted next to the sensor, with a gradual turn on at approx. 30% FSO.
