druksensor

Druksensor is a device that measures the pressure of gases or liquids. It converts pressure into an electrical signal that can be read by data acquisition systems. Druksensors are used in a wide range of applications from consumer devices to industrial systems. They come in various technologies, including piezoresistive, capacitive, piezoelectric, and optical types, each with its own advantages and limitations. Piezoresistive sensors use a diaphragm with a bonded resistive element; deflection changes resistance and is easy to integrate with ICs. Capacitive sensors measure changes in capacitance as a diaphragm moves. Piezoelectric types generate an electrical charge under stress and are well-suited for dynamic pressure, whereas optical sensors use fiber optics to detect bending or refractive index changes.

Druksensor outputs may be analog, such as voltage (0-5 V or 0-10 V) or current (4-20 mA), or digital via interfaces such as I2C or SPI. They can measure absolute pressure (relative to vacuum), gauge pressure (relative to ambient), or differential pressure (between two ports). The measurement range spans from sub-psi to thousands of psi, depending on design.

Applications include automotive turbocharger and manifold pressure sensing, tire pressure monitoring, HVAC and fluids control, industrial process monitoring, medical devices, weather instrumentation, and aerospace. Key considerations include accuracy, temperature stability, response time, electrical interface, power consumption, and environmental protection.

Calibration is typically performed against traceable standards to maintain accuracy, and many devices are compensated for temperature effects. Druksensors continue to evolve with smaller form factors, lower power, and higher resolution to support precision measurement in embedded systems.
