Electronic Digital Differential Pressure Switch Sensor NT80D series

Principle Characteristics

The NT80D uses a diffused silicon sensor for pressure measurement, and the signal is processed by a post-processing circuit and converted into a standard industrial electrical signal for output and display. The all metal shell design and high brightness LED digital display enable this series of products to be used in various industrial applications. The double bond design and menu make the product more convenient to use, and multiple connection methods can fully meet various specific installation needs. The display head that can rotate 330 ° ensures the best viewing angle under different installation methods.
