TT Electronics OPB350 and OCB350 Liquid Sensors

TT Electronics OPB350 Liquid Sensors detect liquid conditions in clear tubes through an optical LED and phototransistor arrangement and require external circuitry to distinguish fluid present and no fluid states. The sensors are available in PCB mount and wired configurations, with customer circuitry adjustable manually or automatically adjusted to accommodate sensor and application variations.

The OCB350 Liquid Sensors combine an OPB350 sensor with an OCB100AZ calibration circuit to provide automatic calibration and a preset trip level. The integrated circuit provides analog and logic outputs and retains the calibrated setting after power loss.

The OPB350 and OCB350 Tube Liquid Sensors are non contact optical sensors designed to detect liquid conditions in clear tubes. Both series support 1/16", 1/8", 3/16", and 1/4" tube outside diameters and use an optical LED and phototransistor arrangement to detect changes caused by liquid in the tube. Applications include water, coloured fluids, oils and petroleum products, IV fluids, and toner fluids.
