ND Series
Absolute pressure sensors
Industrial grade sensors with extended temperature range for measuring absolute pressures
The ND Series of absolute pressure sensors extends operating temperatures from -20°C to +85°C and supports pressure ranges from 15 psia to 150 psia, making them ideal for applications requiring precise air and gas pressure measurements relative to absolute zero.
The ND Series offers advanced integration by combining a state-of-the-art piezoresistive sensing element with integrated amplification, ADC, DSP, and a digital interface, significantly simplifying customer integration. The use of advanced digital processing introduces enhanced functionality, streamlining system development, manufacturing, and improving overall reliability.
Designed with flexibility in mind, the ND Series features an advanced programmable bandwidth filter, integrated notch filter, and optional features such as pressure switches and closed-loop control capabilities, making these sensors a versatile solution for complex industrial environments.
