Fluid Sensors from TT electronics OPTEK Technology

TT electronics OPTEK Technology

TT electronics OPTEK Technology, Carrollton, TX, offers the OCB350 Series fluid sensors with self-calibration circuitry. The sensors use an LED/phototransistor to sense the change in refractive properties between full and empty tubing as it passes through the sensor housing. The calibration circuit lets you narrow the expected output state, allowing the sensors to operate with the same start-up setting for years. The sensors design minimizes the effects of changes in the sensor's optics due to manufacturing variances, ambient light, temperature fluctuation, and degradation of the LED and phototransistor over time.
