ZNC-FRC-EXT Explosion-proof Thermal Flow Switch (for High Temperature & High Viscosity Media)

Overview of ZNC-FRC-EXT Explosion-proof Thermal Flow Switch

The ZNC-FRC-EXT is an intelligent electronic switch designed specifically for monitoring flow in hazardous zones where high-temperature or high-viscosity fluids are processed.

What is it? The ZNC-FRC-EXT is a flameproof flow monitor that uses thermal dispersion technology to sense the flow status of water, oils, and chemical media. Unlike standard switches, the "EXT" model is ruggedized for extreme heat and thick fluids. It serves as a critical safety device, triggering alarms or system shutdowns to prevent pump failure or equipment damage in hazardous atmospheres.

Principles of Operation: The device operates on the thermal principle, where a heated probe tip measures heat loss caused by the flowing medium.

The ZNC-FRC-EXT features an integrated probe and advanced surface-mount circuitry. As the medium flows past the probe, the rate of heat dissipation is measured; the internal circuit then compensates for the ambient medium temperature to provide a precise flow velocity reading and switch output.

Main Application Field: This switch is tailored for the petroleum, chemical, and metallurgical industries. It is particularly effective in monitoring thick crude oil, high-temperature lubricants, and specialized chemical reagents in Zone 1 and Zone 2 explosive environments.

Key Characteristics: The defining features are its non-mechanical design (no parts to clog or wear) and its wide temperature tolerance (-45°C to 300°C). The integrated structure and low power consumption (≤100mA) make it both reliable and energy-efficient for long-term industrial use.

Features of ZNC-FRC-EXT Explosion-proof Thermal Flow Switch

1. High Temperature Tolerance: Specialized construction allows for continuous and reliable operation in medium temperatures ranging from -45°C to 300°C.

2. Explosion-proof Construction: Certified to ExdⅡCT6 standards, ensuring the housing can contain internal sparks and safely operate in explosive gas atmospheres.

3. Non-mechanical Design: No moving parts means the switch is immune to mechanical fatigue, sticking, or clogging, making it perfect for high-viscosity oils and fluids with small particles.

4. Intelligent Temperature Compensation: A built-in compensation circuit minimizes measurement errors caused by rapid changes in the medium or environmental temperature.

5. High Reliability & Stability: Utilizes advanced surface-mount technology (SMT) for the internal circuitry, extending the service life and improving resistance to interference.

6. Easy Installation: Compact, integrated design with standard threaded connections facilitates quick setup in complex industrial piping.
