Intelligent Temperature Controller NT50 | Digital Temperature Controller

Brand: NOIKE-AH
Model:NT50

Specification

Product Summary

The NOIKE-AH Intelligent Temperature Controller NT50 is a compact all-in-one instrument that integrates temperature measurement, display, switching output, and control into a single device. Equipped with a high-precision temperature sensor, advanced A/D conversion, and intelligent digital processing, the NT50 provides reliable temperature monitoring and automatic control for industrial processes.

Featuring a 4-digit LED display, dual programmable switching outputs, and optional analog output, the NT50 is suitable for real-time temperature monitoring, over-temperature protection, and automated process control in water treatment, chemical processing, machinery, and industrial automation systems.

Working Principle

The NT50 operates using a high-precision electronic temperature sensing system.

The integrated temperature sensor continuously measures the process temperature and converts it into an electrical signal. After high-resolution A/D conversion and digital signal processing, the controller displays the temperature in real time and compares it with the user-defined set points.

When the measured temperature reaches the preset high or low limits, the controller automatically activates the corresponding switching output for alarms, cooling systems, heaters, pumps, or other control equipment.
