Light Transducer LXT
light transducer with warning  device for fixed  mounting and with output and control relay 

The light transducer LXT with warning function consists of a measurement sensor and a small wall bracket or holder with a 1.5 m cable, a light transmitter as well as a digital display. The application field of the fundamental light transducer LXT is the continuous measurement of daylight and light control in photo labs and production facilities (for example in the manufacture of food or medicines ...). The digital display of the light transducer LXT has an output relay to control audible alarms, flashing lights, etc, as a warning and optical or acoustic control and output regulation. The limit value for the light transducers LXT for the analogue alarm output can be programmed on the screen. The digital analogue output of the light  transducer LXT can be used to control valves or to keep the signals from the transmitter in a data logger, to asses them and to document them. The warning of the light transducer is very easy to connect and it is powered by a current of 240 V. At the following link, you  will find other light transducers.

The display for the light transducer LXT is introduced in the light transmitter and it starts working immediately.

The warning light transducer is designed for long-term measurements of light output. The light  transmitter and digital display of the  transducer have standard measures and they can be adapted to any distribution cabinet that has standard drawers. The warning light transducer is particularly suitable for the control in companies that manufacture or store material that are sensitive to light.
