Digital Display Temperature Sensor (Explosion-Proof Type) NT50EX-20 Series

Product Overview

The NT50EX-20 series utilizes ceramic thick-film sensors for temperature measurement. The signal is processed by the post-processing circuit and converted into a standard industrial electrical signal for output and display. Featuring an explosion-proof housing design and high-brightness LED digital display, this series of products can be used in various industrial occasions. The dual-button design and menu make the product more convenient to use, and multiple connection methods can fully meet various specific installation requirements. The 330° rotatable display head ensures the best viewing angle under different installation methods.

Panel Introduction

  • 1-channel switch signal lamp
  • 2-channel switch signal lamp
  • Shanghai Zanke NT50EX Series
  • S1, S2: Up menu/decrease number key, Down menu/decrease number key
