ESM2088WLPSF 4-20mA output Corrosion-resistant Submersible level meter sensor with 1meter 3meter 5meter 10meter

 ESMWLPSF Submersible level sensor according to the proportional relationship between the static pressure within a liquid and the liquid level height, the measurement is carried out using the formula P = ρ × g × h(where P is the static pressure, ρ is the liquid density, g is the acceleration due to gravity, and h is the liquid level height). The pressure-sensitive element inside the sensor probe detects the static pressure, converts the pressure signal into an electrical signal, and then transmits it via a cable to a display instrument or control system, where it is finally converted into the liquid level height.

1. Excellent corrosion resistance: Can withstand corrosion from most strong acids (such as hydrochloric acid and sulfuric acid), strong alkalis, and organic solvents, making it especially suitable for harsh environments like electroplating tanks, pickling tanks, and sewage treatment pools.
2. Lightweight: Compared to metal casings, PP material is lighter, making installation and hanging easier.
3. Cost-effective: In highly corrosive environments, the cost is much lower than using sensors made of Hastelloy or titanium alloys.
4. Limitations: Temperature resistance is generally not as good as metals (usually the medium temperature is between -20℃ and 80℃, depending on the manufacturer's process), and it is not resistant to high-pressure impact, making it unsuitable for high-temperature and high-pressure environments.

1.Environmental Water Treatment: Monitoring liquid levels in sewage tanks, balancing tanks, and neutralization tanks.
2.Chemical Industry: Liquid level control in acid and alkali storage tanks, reaction kettles, and electrolytic cells.
3.Electroplating Industry: Automatic replenishment control of plating solution in plating tanks.
4.Urban Water Supply: Monitoring water levels in underground wells and water tanks (if the water quality is not highly corrosive, stainless steel is usually used, but PP is also acceptable).
5.Marine Engineering: Measuring seawater levels (attention should be paid to the anti-aging performance of PP in seawater, and sometimes PVDF is used as a substitute).
