Light Level Sensors & Transmitters

Product Information:

The ACI/LLS is a light sensitive resistive sensor which may be used as an input to indicate the amount of light available at the sensor location. The unit is designed to be mounted in either the end of a waterproof conduit box or as a snaptrack mount.

The ACI/LLS has a resistance in darkness in excess of 1M ohm and a resistance in bright light of less than 1.5K ohm.

The ACI/LLS-T incorporates a transmitter with the sensor to produce a 4 to 20 mA signal.

The ACI/LLS-T unit is calibrated for 4mA in bright light and 20mA in darkness.
