Types of Pressure Sensors
Absolute Pressure Sensors
- For measuring air pressure, especially in applications like weather barometric readings and altimeters, absolute pressure sensors are the go-to choice.
- They establish absolute measurements by comparing the target pressure to the known pressure of an absolute vacuum, similar to measuring temperature in Kelvin, starting from 0 °K.
- An absolute sensor with a 10mV/V output yields a 0 – 50 mV output with a 5.0 VDC supply. These sensors are usually minimal, with pads or legs suitable for circuit board soldering.
- In contrast, a ‘transducer’ is a comprehensive sensor with built-in signal conditioning for direct use in industrial settings.
- Typically, it provides a voltage output representing pressure, often within the 0 – 10V range, or generates an alternating signal in the 1 – 6 kHz range in some cases.
Piezoelectric Pressure Sensors
- Piezoelectricity is the generation of electric charge in specific materials when subjected to mechanical stress.
- Piezoelectric pressure sensors utilize this phenomenon by measuring the voltage produced across a piezoelectric element due to applied pressure. These sensors are highly durable and find extensive use in various industrial applications.
- Moreover, engineered ceramics can be crafted with the necessary polarization to render them piezoelectric. These ceramics offer greater sensitivity than natural crystals. Even a minimal 0.1% deformation can generate a valuable output.
- The output maintains linearity across a broad range, usually spanning from 0.7 KPa to 70 MPa (0.1 to 10,000 psi) with approximately 1% accuracy.
MEMS Pressure Sensors
- Microelectromechanical systems (MEMS) devices merge tiny mechanical and electronic parts onto a silicon chip.
- The same manufacturing methods used for creating transistors and other components in integrated circuits (ICs) can also be applied to build mechanical elements like springs, flexible membranes, vibrating structures, valves, gears, and levers.
- This technology enables the production of various sensors, including various types of pressure sensors.
- It allows for the integration of precise sensors, robust processing, and wireless communication (e.g., Wi-Fi or Bluetooth) within a single IC.
Optical Pressure Sensors
- The optical pressure sensors offer precise pressure measurements with temperature compensation.
- They have a measurement range spanning from 0 to 100 bar, boasting a remarkable resolution of 0.1% of the full scale.
- These sensors exhibit exceptional accuracy, with deviations of less than 1% of the full scale.
- Furthermore, they can accommodate up to 96 measurement points when used with a 16-channel si255, allowing for the connection of six sensors per channel. The pressure inlet port features a G 1/8th thread for secure and reliable pressure input.
Capacitive Optical Sensors
- Capacitive sensors have a broad temperature operating range and can tolerate short-term overpressure conditions effectively.
- They are versatile, and capable of measuring pressures from vacuum levels (2.5 mbar or 250 Pa) to high pressures up to approximately 10,000 psi (70 MPa), making them suitable for both lower-pressure applications and moderately challenging environments.
- These sensors are inherently low-power as they don’t require DC current flow through the capacitor.
Pressure Sensor Reliability and Repeatability
- For most applications, it’s crucial to have a differential pressure sensor that meets high standards of accuracy, repeatability, reliability, and stability.
- The objective is to ensure that HVAC systems operate at peak efficiency with minimal downtime.
- Therefore, pressure measurement instruments are required to incorporate dependable sensor technology capable of detecting even the slightest pressure differences while maintaining accuracy and reliability over time.
- While you may aim to save energy by precisely controlling temperature, the accuracy of the differential sensor plays a pivotal role.
- If the sensor’s accuracy shifts from +/- 0.25% to +/- 1.0% or more at any point, it can disrupt the precise control of the process and lead to increased energy costs.
Latest Trends in Pressure Sensor Technology
