Anhui Huanrui Unveils TC-200/300 Smart Explosion-Proof Temperature Controller: Precision and Safety for Industrial Heat Tracing

In demanding industrial environments, temperature control is more than a matter of efficiency—it is the frontline of operational safety. Anhui Huanrui has officially launched the TC-200/300 Smart Digital Display Explosion-Proof Temperature Controller, a high-precision terminal designed specifically to serve as the "intelligent brain" for advanced electric heat tracing systems.

核心优势 (Key Highlights)

Dual-Mode Intelligence: Featuring a high-contrast digital interface for local monitoring and RS485 Modbus RTU support for seamless remote integration, reducing the need for manual on-site intervention.

Comprehensive Data Visualization: The unit displays temperature, current, voltage, and hysteresis values simultaneously, ensuring operators have a full diagnostic picture at a glance.

High-Precision Sensing: Equipped with a built-in PT100 sensor, the controller maintains a rigorous accuracy of ±0.5°C.

工业级防爆等级 (Industrial-Grade Explosion Protection)

The TC-200/300 is engineered for the world’s harshest "Zone 1" and "Zone 21" environments, meeting stringent safety standards:

Protection Type Certification Code Application Area

Gas Explosion-Proof Ex db IIC T6 Gb Zones 1 & 2 (including Hydrogen & Acetylene)

Dust Explosion-Proof Ex tb IIIC T80°C Db Zones 21 & 22 (Conductive Dust)

Ingress Protection IP66 Complete protection against dust and high-pressure water jets

The unit is housed in a heavy-duty 304/316 Stainless Steel or Carbon Steel flameproof enclosure, ensuring durability against corrosive and volatile atmospheres.
