The pressure sensor range refers to the minimum and maximum pressure a sensor can measure accurately. Choosing the right range is crucial for ensuring precise and reliable measurements in industrial applications.
1. How to Determine the Right Pressure Range
Selecting the correct range depends on:
- Operating Pressure: The typical pressure the sensor will measure.
- Overpressure Tolerance: The maximum pressure the sensor can handle without damage.
- Burst Pressure: The pressure at which the sensor will fail or rupture.
- Application Requirements: Process conditions such as temperature, media type, and safety margins.
Example:
If your system operates at 100 bar, selecting a sensor with a range of 0-150 bar ensures accuracy while protecting against overpressure.
2. Common Pressure Ranges
Different industries require different pressure ranges based on their application needs.
| Application | Common Pressure Range |
| HVAC Systems | 0-10 kPa (low pressure) |
| Medical Devices | 0-50 kPa |
| Automotive (Fuel Injection) | 0-5 MPa |
| Industrial Process Control | 0-100 MPa |
| Oil & Gas (Well Pressure) | 0-200 MPa |
| Hydraulic Systems | 0-700 bar |
3. Types of Pressure Sensors Based on Range
- Low-Pressure Sensors (0-10 kPa): Used for air and gas pressure monitoring.
- Medium-Pressure Sensors (10 kPa – 10 MPa): Suitable for process control and automotive applications.
- High-Pressure Sensors (10 MPa – 100 MPa+): Used in hydraulic systems, oil & gas, and aerospace.
