4-20ma ouput ESM2088WLPS Water reservoir, fish pond, crude oil storage tank level detection pressure sensor with 24vdc

The ESM2088WLPS submersible level sensor is a high-precision liquid level measuring instrument based on the hydrostatic principle. Its core feature is the use of an internationally standardized 2088 cast aluminum or stainless steel junction box, offering excellent protection (IP65/IP67) and electromagnetic compatibility. The sensor submerges its probe at the bottom of the liquid via a dedicated vented cable and converts hydrostatic pressure into a standard 4-20mA current or digital signal output using the formula P = ρgh.

The product is easy to install (direct immersion), unaffected by surface foam, steam, or color, and is widely used in municipal water supply, sewage treatment, deep well monitoring, and industrial storage tanks. Its standardized housing design ensures excellent interchangeability and maintenance convenience, making it the first choice for stable and reliable level monitoring under complex conditions.

    Working Principle

    ESMWLPS 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.

    Product Features

    1. Large wiring space: The interior is spacious, making it easy for electricians to perform wiring operations, and even allows for installing lightning protection modules, signal isolators, and other accessories inside.
    2. Good heat dissipation: The cast aluminum housing has excellent heat dissipation, suitable for high-temperature environments or high-power circuits.
    3. Strong anti-interference capability: The metal housing provides natural electromagnetic shielding (EMC), suitable for environments with strong interference such as inverters and motors.
    4. Visibility (optional): Many 2088 meters can be equipped with an LCD display or LED digital display, showing the current water level directly on-site without the need for a handheld terminal.
    5. Convenient maintenance: The circuit board can be serviced by simply opening the cover, without having to disassemble the entire sensor.

     application  scenario

    1. Urban water supply: clear water tanks at water plants, elevated water tanks, underground reservoirs.
    2. Wastewater treatment: adjustment tanks and aeration tanks at wastewater plants, sewage pumping stations (requiring anti-clogging probes).
    3. Water resources and hydrology: water level monitoring of rivers, lakes, reservoirs, and groundwater wells.
    4. Industrial storage tanks: chemical acid and alkali tanks, oil tanks, cooling towers, boiler steam drums.
    5. Firefighting systems: monitoring the water level of fire water tanks and linking to makeup pumps.
