1、 Main function: S3 series products are used for measuring the liquid level of sewage tanks or other unclean liquids. With a unique design, they can work for a long time in harsh environments The outer sleeve is easy to disassemble and clean. 2. Features: simple structure, easy installation, strong corrosion resistance, long service life, and good seismic resistance. Widely used in vehicles, ships, generators, engineering, machinery, chemical tanks, and pipeline sewage tanks. 3、 Basic working principle: The change in liquid level causes the floating bucket to slide up and down along the electronic tube. At the same time, the magnetic spring switch at different positions inside the electronic tube is driven by the magnet of the floating bucket, causing the electronic signal of the internal circuit to change in real time. Then, the change is fed back to the instrument through wires, and finally the correct liquid level is displayed by the swinging position of the instrument pointer. S5 sensor liquid level probe measurement sensor, oil level and water level sensor, oil float (simulation, switch signal) 4.
