Electronic Digital Pressure Sensor NT80D series | LED Differential Pressure Switch
- Brand：NOIKE-AH
- Model：NT80D
Specification
Product Overview
The Digital Pressure Sensor NT80D uses a diffused silicon pressure sensor to accurately measure pressure. The measured signal is processed by a post-processing circuit and converted into a standard industrial electrical signal for display and output.
Featuring an all-metal housing, a high-brightness 4-digit LED display, and a 330° rotatable display head, the NT80D is designed for a wide range of industrial applications. Its dual-button menu system simplifies configuration, while multiple process connection options allow flexible installation in different operating environments.
Why Choose the Digital Pressure Sensor NT80D ?
The NT80D combines pressure measurement, digital display, switch output, and analog output in one compact device. It offers configurable PNP/NPN outputs, optional 4–20mA analog output, and a durable stainless steel construction for reliable operation in industrial automation systems. The rotatable display head also provides excellent visibility regardless of the installation position.
