The CARLO GAVAZZI VPA2MPA-1 is a robust optical level probe designed for detecting liquids using modulated infrared light. This self-contained unit incorporates a built-in amplifier and separate transmitting/receiving elements sealed behind the tip, enabling direct mounting through tank walls. The polysulphone tip provides excellent chemical resistance to acids and bases, while the liquid and electrical circuit remain completely isolated. Suitable for a wide range of industrial applications including tank level monitoring in chemical processing, food and beverage, and wastewater treatment, the VPA2MPA-1 offers reliable and accurate level detection even in challenging environments.
