Low pressure sensors play a vital role in a multitude of modern-day, everyday applications. A wide range of these types of sensors are available for measuring pressure, usually that of liquids or gases. A reputable company in the industry can help you choose a sensor and can even customize a sensor for your particular application.
Variable Reluctance Sensor
One type of sensor available on the market today is the low pressure variable reluctance sensor. These low pressure sensors have a low internal volume coupled with a natural frequency that is high. You can get one of these sensors in a wide array of pressure ranges, ranging from +/-0.6 to 90 in H2O FS. These sensors’ construction allow for small volumes of displacement because each sensor is symmetrical. You can easily take a sensor apart to clean it or change the pressure range.
Sensor for Clinical Settings
Another type of low pressure sensor is designed specifically for airflow measurements and pulmonary pressure in the clinical setting. This type of quality sensor offers a rapid dynamic response, featuring differential pressure ranges starting at +/-2 cm and going up to +/-880 cm H2O. These types of sensors are usually used in tandem with pnuemotachs for the purpose of measuring expiration and inspired flow rates. When looking for one of these sensors, be sure the one you choose is approved by the Food and Drug Administration.
Inert Gas Sensor
A very low pressure variable reluctance sensor is also available if you need to measure pressure changes and pressures that are extremely low, going down to +/- 0.005 psid. These types of sensors are suited for inert gases and air.
The best models of these types of low pressure sensors are very accurate when it comes to detecting minor leaks, and this particular sensor can also be used in a pressure null detection system. This sensor will work a distance of 1,000 feet from supporting electronics with no compromise in its accuracy. The experts at a company that manufacturers these three sensors can help you determine which type is most appropriate for your specific application.
