Smart PID Temperature Controller (CH702/CH902 Series)

1. Product Overview

This high-performance PID Temperature Controller regulator delivers precise and stable temperature control for a wide range of heating applications. Built with imported control chips and SMT technology, the controller offers accurate readings and reliable operation in complex industrial environments. Supporting universal sensor inputs and dual control outputs, this versatile device works seamlessly with ovens, furnaces, and other heating equipment. With dual alarm functions and sensor breakage protection, it ensures both operational safety and consistent performance for long-term use.

2.Application Environment

PID Temperature Controller Designed to withstand typical industrial conditions, the controller operates reliably within an ambient temperature range of 0°C to 50°C, suitable for most factory and workshop settings. Featuring strong anti-interference performance, the controller maintains stable operation even in environments with electromagnetic interference from motors, inverters, or other industrial equipment. Widely used in industrial ovens, packaging machinery, plastic processing equipment, and laboratory heating systems, it provides dependable temperature control for both low and high-heat applications.

4. Product Features

Equipped with high-quality imported chips for fast response and high-precision regulation, the controller reduces temperature overshoot and fluctuation during operation. A dual LED display shows real-time process value (PV) and set value (SV) at a glance, with clear indicator lights for output and alarm status. It also includes sensor breakage protection: if the temperature sensor is damaged or loses contact, the device will automatically disconnect the heating output to prevent equipment damage. A flame-retardant housing and strong anti-interference performance ensure stable and safe operation even in harsh industrial environments.

5. Installation and Usage Instructions

Before installation, confirm the model and installation size match the equipment’s control panel opening. Mount the controller securely into the panel, then connect the power supply, temperature sensor, and control output according to the provided wiring diagram. When using the device for the first time, complete the self-tuning function to optimize PID Temperature Controller for your specific heating load, ensuring the most stable control effect. Set the desired temperature and alarm values via the front panel buttons, and check the status indicators to confirm normal operation. Regularly inspect the wiring and sensor connections to maintain performance and extend service life.
