Providing design engineers with a simplified means of detecting the presence of fluid in transparent tubing, Optek Technology has expanded its family of fluid sensors to include automatic calibration circuitry and a preset trip level feature.
The liquid sensor consists of an LED and phototransistor packaged in an opaque plastic housing that enhances ambient light rejection. The housing features an opening designed to accommodate clear tubing with outer diameters of 1,6 mm, 3,2 mm or 4,8 mm. The presence of clear liquid causes the phototransistor to sink the maximum current, while the presence of dark liquid causes it to sink the minimum current. As bubbles pass through the tube, the signal will vary between the 'liquid present' and 'no liquid' states. If no tube is present, the phototransistor sinks current between the dark fluid and clear fluid states.
The OCB350 is designed to maintain the calibrated setting even if power is lost. Designers can initiate the calibration procedure at any time. The output phototransistor features a maximum collector-emitter voltage of 24 V or 30 V, with collector DC current of 50 mA and power dissipation to 100 mW. Operating temperature range is from -40°C to +85°C.
The sensors are ideally suited for non-contact fluid sensing applications including IV fluids, oils and other petroleum products, coloured fluids, toner and water.
