2 Specifications are subject to change without notice (02.03.2006) Specifications (cont.) Mode of Operation The sensor contains IR trans- mitter, receiver and amplifier with transistor or SCR output. The light source is a Ga-As diode emitting infrared light. The conical tip of the sensor forms an angle of 90ºC. This angle acts as a prism, i.e. the beam, emitted from the Ga- As diode placed in one side of the sensor head, is reflect- ed internally to the phototran- sistor placed in the other side of the sensor head, provided that the tip of the sensor is si- tuated in free air. If the sensor tip is immersed in a liquid, always having a refractive index different from air, the beam will not be refracted by the prism and the photo tran- sistor will not receive any sig- nal. The sensor types can operate in oil, waste water, aqueous solutions such as beer, wine, alcohol etc. without any kind of accessory.
