There are many different types of pressure sensors available on the market. You should opt for one that provides accurate measurements even in harsh environments while resisting corrosion and other damage. Also, the best sensor depends on the type of application or sector you are using it in. There are some distinct features to consider when you’re in the market for an atmospheric pressure sensor.
Four Types of Pressure Sensors
- Absolute pressure sensors use a perfect vacuum as a reference point. This is the ideal type of sensor for measuring vacuum or positive pressures.
- Differential pressure sensors measure the differential between two pressures, allowing you to track fluctuations in system pressure.
- Gauge pressure sensors measure the pressure at its port in relation to the local atmospheric pressure. As a point of reference, it uses an atmospheric pressure of 1.01325 bar or 15 pounds per square inch.
- Multivariable pressure sensors measure both absolute and differential pressure and then adjust according to temperature measurements.
Each type of atmospheric sensor has its advantages and disadvantages. Absolute pressure sensors are most accurate but can be expensive. Differential pressure sensors are less sensitive to barometric changes but ideal for outdoor use. Gauge pressure sensors are easy to use and affordable but are less accurate. Whichever type of sensor you choose, make sure it meets your specific requirements.
Pressure Range of the Sensor
The pressure range of your atmospheric pressure sensor will determine how much it can measure. The ideal atmospheric pressure sensor should be able to measure a wide range of pressures, from near-vacuum to high positive pressures. If you want more accurate readings, you can choose one that has a wider range than you need, though you’ll need to calibrate it often.
Conditions of Application
You also need to consider how corrosive substances could affect atmospheric sensors while in use. If you’re using the sensor in a laboratory, for example, you might need to wet the seals to protect them from solvent corrosion. You’ll also need to take special care to protect the sensor’s internal electronics from damage. Process media or high humidity can reduce a transmitter’s accuracy and increase the risk of component failure.
When you install new components, it often causes the facility’s production to slow down. This is due to the time it takes to integrate the new parts and make sure they work correctly. This is usually because there are a lot of new things to learn in a short amount of time. You also need to make sure that these new components are easy to use and don’t take up too much space. That way, installing them won’t take too long.
