A/LLS

The light level sensor and transmitter is to be used for applications such as turning on or off indoor or outdoor lighting based upon the amount of available light. These sensors are not to be used in applications such as green houses where the actual amount of light is monitored. This unit is can be mounted in the end of a waterproof conduit box or comes standard mounted in a clear threaded case.

The A/LLS has a resistance in darkness in excess of 1M ohm and a resistance in bright light of less than 1.5K ohm. The A/LLS-T incorporates a transmitter with the sensor to produce a non-linear 4-20 mA output signal. The A/LLS-T is calibrated for 4 mA in darkness and 20 mA in bright light.
