Accurate low-pressure monitoring is crucial for safety in air flow measurement, leak detection systems cleanrooms, isolation rooms and other critical applications in healthcare, semiconductor manufacturing and more. However, measuring very low pressures in small volumes with accuracy and repeatability requires a specialized sensor. It is the sensor’s design, manufacturing process and installation method that will determine whether or not it can deliver the long-term stability, accuracy and resolution necessary to provide meaningful measurements. That's where microelectromechanical systems (MEMS) can help. Ashcroft, a recognized leader in pressure and temperature instrumentation, and its parent company Nagano Keiki Co. LTD have a proven track record of manufacturing excellence in low-pressure pressure sensors with MEMS technology. Read this article to learn more about MEMS, how it works in low-pressure applications and the pressure sensors available to keep low-pressure environments working with precision and reliability.

Whether you are measuring low-pressure airflow in a critical environment, high-pressure mobile hydraulics in OEM applications, or even ultra-high purity gases in semiconductor manufacturing, you are likely relying on a pressure transducer to keep your system running safely and efficiently. In each of these instances, the challenge is selecting the best transducer for the specific application, especially when there are so many options available to you. Ashcroft and its parent company Nagano Keiki Co. LTD have a proven track record of reliability and excellence in pressure measurement instrumentation.
