In industrial automation, pressure sensors are a critical component for ensuring efficiency, safety, and reliability. Pressure sensors are used in a variety of applications, including process control, leak detection, and material handling. In this article, we will explore what you need to know about pressure sensors for industrial automation.
- Types of Pressure Sensors
There are several types of pressure sensors used in industrial automation. The most common types include:
- Absolute pressure sensors: measure the pressure relative to a vacuum
- Gauge pressure sensors: measure the pressure relative to atmospheric pressure
- Differential pressure sensors: measure the pressure difference between two points
- Vacuum pressure sensors: measure pressures below atmospheric pressure
- Considerations for Selection
When selecting pressure sensors for industrial automation, there are several factors to consider, including:
- Range: the range of pressures that the sensor can measure.
- Accuracy: the degree of accuracy with which the sensor can measure pressure.
- Output: the type of electrical signal output by the sensor, such as voltage or current.
- Environmental conditions: the conditions in which the sensor will operate, including temperature, humidity, and the presence of corrosive or explosive gases.
- Mounting and installation: the method of mounting and installing the sensor in the system.
