The HPF-T032(E) & HPF-T034(E) fiber units feature a Fail-safe design using an array style light beam. This Fail-safe detection is available by using two different sensing methods for the upper and lower limits on the level of liquid in a tank. Unlike all known competitive models, the HPF-T032(E) & HPF-T034(E) emitter/receiver arrangement requires a beam refraction of 1,33 to 1,7 in order for the light to be transmitted. This prevents any kind of false detection due to deposits on the inside of the chemical piping. The array arrangement of the fibers provides a much higher contrast signal level and the ability to be unaffected by bubbles as small as 3 mm. The housing is made from GE Ultem(r) plastic, which is highly resistant to most organic solvents and is capable of high temperature exposure. The HPF-T032(E) can be used with pipe sizes from 3 to 13 mm. The HPF-T034(E) takes care of any lager sized pipe sizes from 8 to 19 mm. Each sensor is shipped with a fiber cutter and mounting hardware. Depending on the selected model, PFA or Polyethylene material protects the 5 meter fiber cable from chemical attacks. Features * An array of 16 optical axes eliminates the effects of air bubbles and water droplets * PFA- or Polyethylene-jacketed fiber * Fits a wide range of pipe diameters * Location of the optical axes is clearly marked * The cable diameter of the HPF-T032(E) & HPF-T034(E) is 2,3 mm
