What are Water Pressure Transducers? A water pressure transducer is a precision instrument that converts the physical pressure of water into an electrical signal. Water pressure transducers can be used to monitor real-time water pressure in various applications, including water pipes, storage tanks, water pumps, and underwater equipment.
Sino-Inst offers a variety of water pressure transducers, supporting customization to meet the needs of water pipelines, water tanks, and other water pressure monitoring applications.
The Role of Water Pressure Monitoring
Water pressure transducers are core components of modern fluid management systems. Whether monitoring water levels in large reservoirs or in factory monitoring systems, these sensors provide real-time data to ensure smooth system operation.
Water Pipe Pressure Monitoring
Whether for tap water or wastewater pipes, pressure monitoring equipment needs to be installed on the pipes. This can be a pressure gauge or a pressure transmitter.
Monitoring water pipe pressure can prevent resource waste and reduce the risk of pipe bursts.
Underwater Pipeline and Equipment Pressure Monitoring
For pipelines or equipment installed underwater, IP68 waterproof pressure transmitters can be installed to monitor underwater pressure in real time.
Tank Water Level Monitoring
By using submersible hydrostatic pressure transmitters or installing pressure level transmitters at the bottom of the tank, the water level in the tank can be directly measured.
High-Pressure Equipment Pressure Monitoring
Waterjet cutting technology can cut high-strength materials. The required water pressure is extremely high, reaching 3000 bar to 7000 bar. High-pressure water pressure sensors can be used to accurately measure the water pressure.
Pump Protection
In any piping network, a pump control pressure transmitter is vital. We install these to monitor discharge pressure, ensuring the pump stays within its safe operating curve.
- Pressure Spikes: High-speed sensors detect water hammer before it breaks pipes.
- System Efficiency: Maintains constant pressure in high-rise buildings and factories.
Groundwater Level Monitoring
For environmental and irrigation projects, we rely on groundwater monitoring sensors to track aquifer health. A submersible level probe is lowered into the well to provide real-time data on depth and drawdown.
- Long-term stability: Essential for tracking seasonal water table changes.
- Slim design: Fits easily into narrow boreholes and pipes.
