Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll be discussing pressure sensors used in canals.
Pressure in the Panama Canal and Other Locations
Depending on the direction, the lock system at the Panama Canal lifts or lowers a ship 85 feet to make the transition from the Pacific to the Atlantic Ocean. The pressure can be calculated from Pascal’s Law-
P = pressure (Pa = N/m2)
ρ = density of fluid (Water = 1000 kg/m3)
g = gravity (9.81 m/s2)
h = depth (m)
While the Panama Canal is among the most famous canals in the world, several lock systems exist in the continental U.S. including on the Mississippi River, Saint Lawrence Seaway, the Soo Locks at Sault Ste. Marie, Michigan and others. In addition, dams also control the flow of water along many rivers.
At the Panama Canal, 265 meteorological and 52 hydrometric stations were installed to measure meteorological parameters of pressure, temperature, extreme temperature, humidity, precipitation (quantity and intensity), wind (speed and direction), evaporation, soil temperature, insolation and solar radiation. With the pressure measurements, the hydrometric stations monitor the rivers and lakes levels continuously. Modern pressure sensors allow even more measurements to be made and communicated to remote monitoring locations for a variety of purposes.
