VP01EP Carlo Gavazzi

VP01EP, Photocells Level Sensors Model VP, Non-Modulated Light, VP01EP, Optical Level Sensor with Non-Modulated Infrared Light, for liquid detection. With built-in amplifier. Built-in transmitter and receiver in a solid plastic housing designed for wall mounting. The VP01/02 models are available in a Polysulfone box resistant to most acids and bases. The VP03/04 models are available in a multi-solvent resistant Polyamide 12 case. Designed for ATEX zone 1 where the explosive atmosphere is not usually present. , VP01EP, The sensor contains an IR transmitter, a receiver and an amplifier with transistor or SCR output. The light source is a Ga-As diode that emits infrared light. 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 sensor tip is introduced into a liquid, as long as it 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 attachments.
