Carlo Gavazzi VPA1MNA Optical Stainless Steel Level Sensor with modulated infrared light for detection of liquids. Fitted with built-in amplifier. The Transmitter and receiver are both self contained within the VPA1MNA Polysulphone plastic tip and is designed for mounting into the tank/container wall. The polysulphone tip is especially resistant to most acids and bases.
The Carlo Gavazzi VPA1MNA has a make and break switching NPN transistor output and a 2 meter cable connection. The VPA1MNA requires a 10-40 vdc voltage input and has an LED for output ON indication.
The probe contains IR transmitter, 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. All types of sensors can operate in oil, waste water, aqueous solutions such as beer, wine, alcohol etc. without any kind of accessory.
The Carlo Gavazzi part number is VP A1 MNA.
