MXS03A Pressure Sensor

I. Product Overview

MXS03A Is A model Diffusion‑silicon‑core digital submersible pressure sensor (submersible level transmitter), based on… MEMS The principle of diffused-silicon pressure measurement converts liquid level based on hydrostatic pressure, available in gauge‑type and absolute‑type configurations, with standard equipment included. RS485-Modbus Digital output; designed for monitoring municipal drainage networks, manhole water accumulation, river channels, pumping stations, and urban‑sponge‑city flooding. It is engineered to withstand prolonged submersion in harsh underwater conditions and serves as a flagship pressure‑level sensor for water‑environment monitoring.

II. Core Operating Principle

The probe is immersed in the liquid being measured; the hydrostatic pressure of the liquid acts on the diaphragm of the diffused-silicon sensing element, causing a piezoresistive change in the silicon crystal, and the built-in… Signal Processing circuit  + Wide‑temperature digital compensation converts the pressure measurement into a digital signal and, leveraging the fixed density of the liquid, calculates the real-time liquid level height.

Gauge‑type: Features a built-in venting tube that communicates with the atmosphere, using ambient atmospheric pressure as the reference to eliminate pressure‑fluctuation errors; comes standard with a breathable, moisture‑proof venting box.

Absolute-pressure type: features a vacuum-sealed sensing element, uses absolute vacuum as the reference, and has no vent line; suitable for sealed vessels and applications where atmospheric pressure compensation is not required.

III. Five Core Advantages of the Product

♦ Fully digital temperature compensation: Featuring a built-in multi-point segmented temperature algorithm, it exhibits no significant accuracy drift across high- and low-temperature ranges, outperforming conventional analog submersible sensors.

♦ Flexible selection: Gauge pressure (preferred for open, exposed water bodies), absolute pressure (for closed water tanks) / Pressure vessel), Optional configuration as needed;

♦ Convenient bus networking: Standard Modbus Agreement, direct integration RTU Telemetry device, PLC • The MoXing network management platform offers low-cost construction and cabling.

♦ Wastewater‑resistant optimization: stainless steel probe + Anti‑clogging isolation diaphragm; municipal sewage and sludge‑laden water are less likely to clog the pores, resulting in extended maintenance intervals.

♦ Ultra-low-power customization: Optional sleep‑mode low‑power operation, ideal for remote water‑level monitoring sites without grid power.

Four , Standard Application Scenarios

♦ Municipal drainage: online monitoring of manhole water levels, standing water in main pipelines, and waterlogging at urban flood-prone locations;

♦ Water Resources and Water Utilities: Measurement and control of river water levels, reservoir shallow-water levels, and pump station sump levels;

♦ Sponge City: hydrostatic level measurement for detention ponds, stormwater inlets, and storage tanks;

♦ Environmental wastewater: Level and medium-pressure monitoring for wastewater treatment ponds and small, sealed effluent tanks.
