Selecting the right pressure sensor for each industrial application helps ensure accuracy, durability, and optimal performance. Factors to consider include pressure range, operating environment, output signal, and resistance to chemicals, temperature, or vibration.
Pressure sensors play a critical role in monitoring and controlling pressure in industrial systems. They help ensure safety, increase efficiency, and optimize production processes. However, choosing the right pressure sensor is not always simple, as each application requires a sensor with specific characteristics.
1. Key Factors When Choosing a Pressure Sensor
1.1. Pressure Measurement Range One of the most important factors when choosing a pressure sensor is the pressure range to be measured. If you choose the wrong range, the sensor may be damaged or not provide accurate data. For example:
-
Low-Pressure Applications (under 10 bar): Differential pressure sensors or low-pressure sensors are suitable.
-
High-Pressure Applications (over 100 bar): High-pressure resistant sensors are the optimal choice.
1.2. Operating Environment The operating environment affects the durability and performance of the sensor:
-
Corrosive Chemical Environments: The sensor needs a protective coating or to be made of corrosion-resistant materials such as 316L stainless steel.
-
High-Temperature Environments: The sensor needs to have good heat resistance, often integrated with a heat sink or diaphragm seal.
-
Wet or Dusty Environments: Sensors with IP67 or IP68 ratings help ensure stable operation. (Industrial Term: Ingress Protection (IP) Rating)
1.3. Accuracy The accuracy of the pressure sensor is an important factor, especially in applications requiring detailed data:
-
General Applications: Accuracy of about 1% FS (Full Scale).
-
High-Demand Applications: Accuracy below 0.1% FS.
2. Common Types of Pressure Sensors
2.1. Absolute Pressure Sensors This type of sensor measures pressure relative to absolute vacuum. It is suitable for applications such as measuring atmospheric pressure, aviation applications, and scientific research. (Industrial Term: Absolute Pressure)
2.2. Gauge Pressure Sensors Measures pressure relative to the surrounding ambient pressure. This is the most common type and is used in HVAC, hydraulic, and pneumatic systems. (Industrial Term: Gauge Pressure)
2.3. Differential Pressure Sensors Used to measure the pressure difference between two points, often used in air filtration systems and to measure liquid levels in tanks. (Industrial Term: Differential Pressure)
3. Guide to Choosing Pressure Sensors by Application
3.1. HVAC Systems HVAC systems require pressure sensors with high accuracy to monitor and adjust air pressure. Dwyer is a brand that provides suitable pressure sensor solutions for HVAC, ensuring optimal performance. (HVAC Term: HVAC Pressure Sensor)
3.2. Hydraulic Systems Hydraulic systems require pressure sensors that can withstand high pressure and strong vibrations. Hydraulic pressure sensors must have a robust protective housing and the ability to withstand pressures of up to hundreds of bar. (Industrial Term: Hydraulic Pressure Sensor)
3.3. Food and Pharmaceutical Industries In the food and pharmaceutical industries, pressure sensors must meet high hygiene standards, be easy to clean, and be resistant to chemical corrosion. (Industrial Term: Sanitary Pressure Sensor)
