Intelligent Temperature Controller NT50EX Series | Explosion-Proof Temperature Controller

Brand：NOIKE-AH
Model：NT50EX

Specification

Product Overview

The Intelligent Temperature Controller NT50EX is an integrated industrial instrument that combines temperature measurement, local digital display, signal transmission, and explosion-proof protection in a single device. It utilizes platinum RTD (Pt100) or thermocouple sensing technology together with specially designed electronic circuits to accurately measure and display process temperature while providing multiple signal outputs for industrial automation systems.

Supporting 4–20 mA, 0–5 V, 0–10 V, 1–5 V, and RS485 outputs, the NT50EX enables long-distance signal transmission and seamless integration with PLC, DCS, and SCADA systems. The controller also supports configurable alarm functions and multiple control points, making it suitable for industrial applications requiring both temperature monitoring and process control.

Designed with an Ex dⅡCT6 explosion-proof enclosure and IP65 protection, the NT50EX is suitable for hazardous industrial environments.

Why Choose the Intelligent Temperature Controller NT50EX?

Industrial processes in hazardous environments require reliable temperature measurement together with accurate control and dependable signal transmission. The NT50EX integrates these functions into one explosion-proof device for efficient industrial temperature monitoring.

Integrated Measurement and Control

The NT50EX combines temperature sensing, digital display, signal transmission, alarm functions, and temperature control within a single compact instrument, simplifying system design.

Multiple Output Options

Support for analog outputs and RS485 communication allows easy integration with PLCs, DCS, SCADA, and other industrial automation systems.

Flexible Alarm Configuration

The controller provides two standard control points with expansion to four control points, allowing independent alarm values and hysteresis settings for different process requirements.

Reliable Operation in Hazardous Areas

The Ex dⅡCT6 explosion-proof design and IP65 enclosure make the controller suitable for industrial environments requiring explosion protection.

Stable Measurement Performance

Automatic digital calibration, RF interference suppression, and enhanced surge protection contribute to stable long-term operation in industrial applications.

Application Case

Explosion-Proof Temperature Monitoring and Control in Petrochemical Processes

Temperature monitoring and control are critical in petrochemical processing, where hazardous environments require explosion-proof instrumentation. The Intelligent Temperature Controller NT50EX can be installed at process pipelines, reactors, or storage systems to continuously measure temperature using a platinum RTD or thermocouple.

Measured values are displayed locally while simultaneously transmitted through 4–20 mA, voltage outputs, or RS485 communication to PLC, DCS, or SCADA systems for centralized monitoring and process control. Configurable alarm points enable operators to implement high- and low-temperature alarms based on process requirements.

With its integrated design, explosion-proof enclosure, and multiple communication options, the NT50EX is suitable for temperature monitoring and control in petroleum, chemical processing, power generation, metallurgy, hydrological monitoring, and industrial research applications.
