Superior Sensor ND系列 压力传感器

Based on Superior’s NimbleSense™ architecture, the ND Series family extends the operating temperature down to ‐ 20°C and up to 85°C, while increasing pressures up to 5 psi (345mBar). Additionally, the ND utilizes the company’s proprietary Multi‐RangeTM technology to create the industry’s widest dynamic range. This wider dynamic range offers multiple pressure ranges in a single package thus minimizing the number of sensor variants required to support the demanding functional requirements of the various industrial market segments. For example, one Multi‐Range enabled ND Sensor replaces up to 7 competing products greatly simplifying installation requirements and significantly lowering inventory costs. 

Supporting pressure ranges as low as 0.25 inH2O to as high as 5 psi, the ND Series is ideal for a wide variety of industrial applications from air curtains to aeronautics, from environmental chambers to eye surgery equipment, and from UAVs to 3D Printing. 

The ND Series measures dry air and non‐aggressive gas pressure with very high accuracy and a stable zero point.   Non‐linearity is also industry leading which is typically 0.05% FSS. The ND Series has a selectable bandwidth filter from 1Hz to 200Hz, and 16‐bit resolution. For added performance, the ND Series has incorporated a 50/60Hz notch filter to minimize the impact of power noise spikes. Finally, the ND Series is an excellent choice for applications requiring the utmost reliability.

The ND Series provides a new level of integration combining an advanced piezoresistive sensing element with integrated amplification, ADC, DSP and a digital interface which greatly simplifies customer integration efforts. Advanced digital processing enables new functionality thus simplifying system development, adding manufacturing ease and increasing reliability. 

Constructed with a high reliability plastic enclosure, the ND Series family provides the ideal combination of very high performance and reliability at extended temperature ranges while ensuring customers have a high volume, cost effective solution optimized for a wide array of industrial requirements.
