ND Series

Low pressure differential sensors

Industrial grade pressure sensors with extended temperature range and integrated notch filter

The ND Series extends sensor operating temperatures from -20°C to +85°C, and utilizes Multi-Range™ technology to achieve the industry’s broadest dynamic range. This wider range allows for multiple pressure ranges within a single package, reducing the need for numerous sensor variants to meet the stringent demands of various industrial sectors. For instance, a single Multi-Range enabled ND sensor can replace up to seven competing products, simplifying installation and significantly reducing inventory costs.

With pressure ranges spanning from as low as ±0.25 inH2O (±62.5 Pa) to as high as ±30 inH2O (±7.5 kPa), these sensors are ideally suited for a diverse array of industrial applications, including air curtains, aeronautics, environmental chambers, eye surgery equipment, transportation, and 3D printing.

The ND Series is built with flexibility in mind. Its multiple pressure ranges can be adjusted dynamically, while also offering an advanced programmable bandwidth filter, integrated notch filter, and optional features such as pressure switch and closed-loop control capabilities, making it a versatile solution for complex industrial environments.
