Absolute Pressure vs Negative Pressure: How to Choose the Right Sensor
When selecting a pressure measurement solution, one of the most common questions engineers face is: Should you choose an absolute pressure transmitter or a negative (vacuum) pressure transmitter? At Pokcenser, we specialize in industrial pressure sensing solutions. This guide will help you clearly understand the differences, applications, and how to choose the right product for your system. What Is an Absolute Pressure Transmitter? An absolute pressure transmitter measures pressure relative to a perfect vacuum (0 Pa). Reference point: Absolute vacuum Measurement range: 0 Pa to full scale (e.g., 0–100 kPa) Key advantage: Not affected by atmospheric pressure fluctuations This makes it ideal for high-precision...
