Ambient Light Transducer
The ambient light transducer is a revolutionary new concept in proportional light level monotoring and control.

It provides an analogue output proportional to light measured in lux.

This light level output can be used by any system to turn lights on or off to maintain an ambient light level setpoint.

The transducer incoparates a 100% solid state silicon planar diffussed photovoltiac cell which directly converts light energy into a very small electrical current.

This small current change is used by a state-of-the art integrated circuit signal conditioned to provide a linear, proportional, temperature compensated output in numerous forms to be compatible to all building automation systems.

The transducer is available in a tasteful, aesthetically appealing indoor enclosure or a rugged glass-fibre outdoor unit with remote electronics.

It is an ideal transducer to monitor and proportionally control light level in offices, warehouses, laboratories, greenhouses, parking lots and other light sensitive applications.
