【Product Overview】
FST700-302 water (liquid) level sensor is a capacitive water (liquid) level sensor specially developed for water level detection and alarm on engineering machinery. It is stable, reliable and durable. The product adopts a sealed filling design and the outer shell is made of stainless steel, which improves the product's vibration resistance and anti-destruction performance, ensuring that the product can be used under harsh working conditions. The delay design is adopted to effectively filter out unreasonable signals caused by the ups and downs of the water level caused by vibration.
【Product Features】
● Anti-fouling, anti-rolling, anti-bumping, strong anti-falling, not afraid of magnetic field, not afraid of metal body, not afraid of water pressure change, not afraid of light
● No blind spot, not afraid of solid floating objects
● Flexible installation,
● Can be installed horizontally, vertically, diagonally and other irregular installations, flexible and convenient
【Application Range】
● Applicable to a wide range of industries, such as water plants, precious aquaculture
● Plant breeding, reservoirs, power supply rooms, sewage treatment industries, etc.
● Clean water, various sewage, seawater, water treatment chemicals, river water
● Textile printing and dyeing water, industrial wastewater, also suitable for ship water level switches
