Water Pressure Sensor (0–1.6MPa) | Submersible Level Sensor for Arduino, Tanks & Pumps
Reliable, industrial-grade water pressure sensor designed for accurate water level monitoring, pump protection, and smart system integration.
With a 0.5–4.5V analog output, this sensor works seamlessly with Arduino, PLCs, and home automation platforms—making it ideal for water tanks, irrigation systems, and pump control.
Its IP68 fully submersible stainless steel design ensures stable performance in wastewater, agriculture, and marine environments—while helping prevent costly pump failures caused by low pressure or dry running.
Key Benefits of Water Pressure Tran
Prevent Pump Damage
Real-time pressure monitoring stops dry-running and avoids expensive motor failures
Accurate Water Level Measurement
Continuous analog output enables precise tank level tracking (not just on/off)
Plug-and-Play with Arduino
0.5–4.5V signal, no extra modules required
Fully Submersible (IP68)
Designed for long-term underwater use in harsh environments
Universal Compatibility
G1/4″ thread + G1/2″ adapter fits most tanks, pipes, and systems
Low Maintenance Design
No clogging, no moving parts, no recalibration needed
How Water Pressure Sensor Works
Our sensor measures water level using the hydrostatic pressure principle:
P=ρghP = \rho g h
As water depth increases, pressure rises proportionally. The internal stainless steel diaphragm converts this pressure into a stable electrical signal.
Example:
- 1 meter water depth ≈ 0.1 bar ≈ ~1.6V output

FAQ
1. How does this sensor measure water level?
It adopts hydrostatic pressure principle \(P=\rho g h\). Installed at the bottom, pressure value is directly proportional to water height, delivering stable continuous level data.
2. Is Arduino connection complicated?
No soldering needed. Gravity 3-pin plug-and-play with 5V/GND/A0; the provided code runs directly without extra libraries.
3.What are the advantages over ultrasonic sensors?
Works through foam, vapor and mist; much lower cost; no interference from wind, dust and installation angle.
4. Can it replace marine original sensors?
Yes, same pressure range and thread standard; suitable for Mercruiser, Yamaha outboard engine cooling system.
5. Is it safe for drinking water?
Adopts NSF-61 certified 316L stainless steel and food-grade sealing material, safe for potable water system.
6. How about overpressure protection?
Supports 2 times continuous overpressure and 5 times instant surge pressure, well resistant to pump startup impact.
7. Custom cable length available?
Standard 2m cable; 5m/10m/20m optional, UV and oil resistant polyurethane jacket.
