Low pressure sensors are type of sensor that is used to measure pressure for variety applications where differential pressure measurements are key for operation and data tracking. The pressure they measure typically comes from gas or liquids including corrosive materials. Low pressure sensors can be used a wide range of industry application for measuring pressure, from the automotive industry to the aerospace industry, where proper and reliable pressure measurement is crucial to ensure safe and efficient operation.
How Does a Low Pressure Sensor Work?
This type of sensor acts as a transducer to generate an electrical signal as a function of the pressured that is imposed on it. Sensors act to either complete or break and electrical circuit in order to indicate pressure measurements. The pressure from a material, such as gas or liquid, acts upon the sensor and the sensors converts this action into a signal in order to measure the pressure.
Common Uses for Low Pressure Sensors
This type of sensor is used to control and monitor a variety of everyday applications, such as low fuel pressure. The main purpose for pressure sensors is to sense changes in pressure and give an accurate reading that can be tracked. They can also be used in applications in the aerospace industry for tasks such as altitude sensing. Pressure sensors and any exposed media are typically made from corrosion resistant steel in order to be used in measuring pressure of corrosive gases or liquids.
To work for altitude sensing, the sensor measures pressure relative to altitude, to ensure the plane is soaring at the correct and required altitude for proper flight. Other applications also include, for example, measuring combustion in an engine or a gas cylinder. Pressure sensors can also be used for flow sensing, leak testing, and many other differential pressure measurement applications where accurate and reliable pressure measurements are crucial part of operation, regulation, and calibration tasks.
Important Features
In addition to having all exposed media components made from corrosion resistant steel, low pressure sensors also feature filed replaceable sensing diaphragms that help to lower downtime. Also, even if overpressure is applied to the sensor the diaphragm won’t be damaged and can be used again after recalibration.
