kobold-1016Kobold Instruments' NSD series optical level switch is a low cost solid-state level sensor suited for clear, translucent and non-coating low viscosity liquids. It detects the difference in refraction between the liquid and air. An infrared LED inside the lens transmits a beam of invisible light. In air, the beam is reflected back into the sensing circuit to an infrared detector. In liquid, the beam is refracted away from the detector and results in switch activation or de-activation depending on the switch logic as ordered. The NSD is available in Polysulfone, or 316 Stainless Steel with a Polysulfone lens.
