NT50EX Series Intelligent Temperature Controller

Product Overview‌

The NT50EX Intelligent Temperature Controller is an integrated instrument combining temperature transmission, on-site digital temperature display, and explosion-proof functionality. Its temperature-sensing probe utilizes high-resistance platinum RTDs or thermocouples, with specially processed electronic circuits to ensure accurate measurement and display of on-site temperature values. It supports multiple signal output modes, including:

4–20mA

0–5V

0–10V

1–5V

RS485

for long-distance signal transmission.

Applications‌

Designed for industries requiring temperature measurement, signal transmission, display, alarm, and control, such as:

Petroleum

Chemical

Metallurgy

Power plants

Hydrological monitoring

Defense

Scientific research
