VP02EPM Carlo Gavazzi

VP02EPM, Photocells Nive Sensors VP Models, Modulated Light, VP02EPM, Optical level sensor with modulated infrared light for liquid detection. With built-in amplifier. Built-in transmitter and receiver in a solid plastic case designed for wall mounting. The VP01/02 models are available in polysulfone box resistant to most acids and bases. The VP03 /04 models are available in a multi-solvent resistant Polyamide 12 box. , VP02EPM, The sensor contains an IR transmitter, a receiver and an amplifier with transistor output. The light source is a Ga-As diode that emits infrared light from short pulses. The conical tip of the sensor forms an angle of 90ºC. This angle acts as a prism, that is, the beam emitted by the Ga-As diode located on one side of the sensor head, is reflected internally to the phototransistor located on the other side of the sensor head, provided that the tip of the sensor is outdoors. If the tip of the sensor is introduced into a liquid, which has a refractive index other than air, the beam will not be reflected by the prism and the phototransistor will not receive any signal. The different sensor models can operate in oil, wastewater, aqueous solutions such as beer, wine, alcohol etc. without any type of accessory.
