Why Do Pressure Sensors Have Temperature Drift Issues? In this informative video, we will discuss the critical issue of temperature drift in pressure sensors and why it affects their accuracy. Pressure sensors are essential in various applications, but their performance can be compromised by temperature fluctuations. We will break down the factors that contribute to temperature drift, including the materials used in sensors and their mechanical components.

You’ll learn how temperature changes can impact the resistance of the sensor elements and influence the mechanical properties of the diaphragm, leading to measurement inaccuracies. We will also touch on thermal expansion and its effects on sensor components, particularly in capacitive pressure sensors. Additionally, we will explore how temperature variations can increase hysteresis, affecting the repeatability of pressure readings.

Engineers face challenges in ensuring accurate pressure measurements in environments with changing temperatures. We will outline some strategies used to address these temperature drift issues, including material selection and electronic design adjustments.
