Many factories and processing plants have equipment which utilizes fluids, gases, or steam, and when these things are inside tanks, reservoirs, and piping systems, they can build up an enormous amount of pressure. Unless this pressure is carefully monitored (with equipment like a Rosemount pressure transmitter), explosions and other hazards are a real possibility. Here are some of the most common pressure monitoring methods used today.
Gauge Sensors
Gauge type sensors compare interior pressure to atmospheric pressure. You can see this kind of gauge in action when you use a tire gauge for measuring psi. If you see the gauge at “zero,” then there is no difference between the pressure inside the tire and the atmosphere, so it is completely deflated or flat.
Magnetic sensors
Faraday’s Law makes it possible for magnetic sensors in the magnetic Rosemount pressure transmitter to work. Electromagnets on the outside of the pipe are spaced equidistance apart. As liquid flows through the sensor, it creates a magnetic field which can be measured.
Vacuum Sensors
Since vacuum is the opposite of pressure, a vacuum sensor works in the opposite way gauge sensors work. Instead of measuring pressure above atmospheric pressure, it measures everything below atmospheric pressure.
Vortex Sensors
You can buy Rosemount pressure transmitter equipment which operates on the vortex principle. Here is a brief explanation. If liquid passing through a pipe encounters some resistance, (or slight blockage) it creates a vortex or whirlpool. A man named Karman once discovered these vortices dissipate at regular intervals and can be measured.
Many Other Selections
When you check out your Rosemount pressure transmitter suppliers, you can find a wide range of pressure gauges and transmitters for your business. The best way to determine your needs is to talk to your instrument experts. They help you with your needs for today and the future.
