Nexisense Ship Systems Case: Pressure and Level Transmitter Applications
Intelligent Ship Monitoring and Pressure/Level Measurement
Ship operations involve multiple systems including bilges, fuel tanks, water tanks, hydraulic systems, diesel engines, and alarm systems. Pressure, level, and flow are key measurement parameters. Onboard sensors must provide high-precision measurement and maintain reliability under extreme long-term conditions, strong vibration, and seawater corrosion.
Nexisense ship pressure and level transmitters use stainless steel diaphragm piezoresistive pressure elements combined with dedicated signal processing circuits to convert pressure signals into standard current or voltage outputs. ASIC technology performs non-linearity and temperature compensation, ensuring high accuracy and long-term stability.
To meet the complex marine environment, Nexisense offers sealed welded pressure sensors with high protection ratings, resistant to salt spray and humidity. Optional tantalum or titanium diaphragms and titanium alloy housings are suitable for long-term seawater exposure.
Application Scenarios for Ship Pressure and Level Measurement
Underwater Equipment Monitoring: Measure deep-sea pressure and levels to ensure equipment safety.
Ship Air Compressors and Pneumatic Systems: Monitor air pressure fluctuations to maintain system stability.
Refrigeration Systems: Monitor liquid pressure and temperature to ensure safe and efficient operation.
Engine Control Systems: Real-time collection of fuel pressure, lubrication oil pressure, and coolant level data to enhance engine performance and safety.
Fire Water Pipe Level Monitoring: Ensure sufficient water supply for firefighting systems and enhance safety.
Ship Propulsion Systems: Monitor hydraulic oil and fuel pressures to optimize overall ship power control.
Through these applications, Nexisense pressure and level sensors help ship operators extend equipment life, reduce maintenance costs, and ensure high reliability and measurement accuracy.
