Optical level probe with modulated infrared light for detection of liquids. Self contained unit has built-in amplifier. Separate trans mitting and receiving ele ments sealed behind the tip. Designed for direct mount ing through the wall of a tank. The polysulphone tip is es pe cially resistant to most acids and bases.
• Modulated light
• Built-in amplifier
• Output: NPN or PNP, 4-wire (NO & NC)
• Housing: Stainless steel or nickel plated brass
• Tip: Polysulphone or glass
• High chemical resistance to most acids and bases
• Liquid and electrical circuit completely isolated
• Power supply: DC models 10 to 40 VDC
The probe contains IR trans mitter, receiver and amplifier with open collector NPN or PNP output. The light source is a Ga-As diode emitting modulated, infrared light in short pulses. This level probe is thus insensitive to ambient light (up to 50,000 lux) and suitable even for adhesive liquids. The conical tip of the sensor forms an angle of 90º. 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 reflected internally to the phototransistor placed in the other side of the sensor head (fig. 1), provided that the tip of the sensor is situated in free air. If the sensor tip is immersed in a liquid, always having a refractive index dif ferent from air (fig. 2), the beam will be refracted into the liquid. All types of sensors can ope rate in oil, waste water, aque ous solutions such as beer, wine, alcohol etc. without any kind of accessory.
