Air pressure sensor

Pressure Range: The span of pressure the sensor can measure, typically ranging from a few Pa (Pascal) to several MPa (Mega Pascal). For example, 0-100 kPa or 0-1000 psi.

Output Signal: The type of electrical signal the sensor produces. Common outputs include:

• Analog Output: 0-5V, 4-20mA, or 0-10V.
• Digital Output: I2C, SPI, or UART.

Accuracy: The degree of error or deviation from the true pressure value, usually given as a percentage of full-scale range (FSR). For example, ±0.5% FSR.

Resolution: The smallest change in pressure that can be detected, usually measured in Pascal (Pa) or millibar (mbar).

Operating Temperature: The temperature range within which the sensor operates accurately. For example, -40°C to 85°C.

Compensated Temperature Range: The range where the sensor’s accuracy is maintained despite temperature fluctuations, e.g., -10°C to 60°C.

Power Supply: The voltage required for operation, typically ranging from 3.3V to 24V DC.

Response Time: The time it takes for the sensor to respond to changes in air pressure, often in milliseconds (ms).

Housing Material: The material the sensor is made from, which can vary based on application. Common materials include stainless steel, plastic, or ceramic.

Media Compatibility: The types of gases or liquids the sensor can safely measure. For example, clean air, non-corrosive gases, or vacuum.

Pressure Type: Defines whether the sensor measures gauge pressure (relative to atmospheric pressure), absolute pressure (relative to a vacuum), or differential pressure (difference between two points).
