azbil Semiconductors Wet process A full lineup that reliably liquid levels Application-specific sensors Discrete sensors Product name Pipe-mounted liquid level switches with built-in amplifier / Pipe-mounted / tank-inserted fiber-optic liquid level sensors Process and equipment name Batch, single wafer cleaning equipment Current Issues Current Situation ■ Pipes of various thicknesses in the discharge section. ■ Pipes are too thin for sensor installation. ■ Various liquid states inside the pipes. ■ Air bubbles and cloudiness interfere with reliable detection. ■ Float or electrode sensors are used. ■ Sticking of movable parts and metal contamination. ■ Sensors are used for upper/lower limit detection. ■ No fail-safe measures.

Small diameters of 1/16 inch and 3–7 mm are supported. Pipe-mounted fiber-optic liquid level sensors use 16 optical axes to reduce the effects of air bubbles and water droplets Tank-inserted fiber-optic sensors have no movable parts, and their all-resin structure does not cause metal contamination Lineup of pipe-mounted fiber-optic liquid level sensors with fail-safe protection Model HPQ-T_ _ pipe-mounted liquid level switches with built-in amplifier are available for small (3–7 mm) and ultra-small (1/16") diameter pipes, in addition to standard diameters (φ8–φ 13). The pipe-mounted fiber-optic...
