This tough Industrial Stainless Steel Pressure Sensor is excellent for checking the level of water or other liquids in places like storage tanks, deep wells, or even small rivers. It can accurately measure liquid depths from 0 all the way up to 5 meters.
Because it's made from strong stainless steel, it doesn't rust easily and you can place it directly into water, oil, or even slightly thick liquids without any worries about damage. It’s a very handy Submersible Level Sensor 0-5m that sends out an industry-standard 4-20mA Water Level Sensor current signal.
This type of signal is commonly understood by many industrial control systems (PLCs) and other professional equipment.
You can also easily connect this Gravity Pressure Level Sensor to microcontrollers like Arduino (usually with a simple converter module) for your own science projects or automatic systems, making it simple to monitor liquid levels precisely.
