ZNC-FRC-S Stainless Steel Thermal Flow Switch

Overview of ZNC-FRC-S Stainless Steel Thermal Flow Switch

The ZNC-FRC-S Stainless Steel Thermal Flow Switch is an intelligent electronic switch used for the precise monitoring and control of flow in industrial pipelines.

• What is it? This switch is typically installed in-line or inserted into pipelines carrying water, oil, or gas. It monitors the flow rate in real-time and triggers an alarm signal if the flow falls below or rises above a user-defined set point. This is critical for protecting host equipment from "dry burning" or overheating due to a loss of circulation.

• Principles of OperationThe switch operates based on the thermal principle. The sealed stainless steel probe contains two resistors: one is heated (detection resistance), and the other is unheated (reference resistance). As the medium flows past the probe, it carries away heat from the heated resistor, changing its resistance. The microprocessor compares the two values to determine the flow velocity and triggers the output accordingly.

• Main Application Field: It is extensively used in fluid cooling systems and hydraulic/pneumatic systems. Applications include water-cooled welding machines, laser equipment, vacuum coating machines, electric furnaces, and polysilicon ingot casting furnaces. It is also a standard solution for pump idling protection in lubrication and cutting fluid lines.

• Key CharacteristicsThe most significant advantage is the lack of moving parts, which results in zero mechanical wear and high immunity to interference. It is built entirely of stainless steel to handle high-pressure and high-temperature conditions while offering multiple mounting configurations (plug-in or in-line).

Features of ZNC-FRC-S Stainless Steel Thermal Flow Switch

1. Maintenance-Free Operation: The no-moving-parts design eliminates mechanical failure risks, ensuring long-term reliability without the need for periodic adjustments.

2. Full Stainless Steel Construction: The probe is crafted from high-grade stainless steel, providing excellent corrosion resistance and durability for various industrial media.

3. Wide Media Compatibility: A single device can be used for water, oil, and gas, offering maximum versatility across different plant systems.

4. Versatile Output Options: Supports Relay, PNP, and NPN signals, allowing for easy integration with any PLC or industrial control unit.

5. High Pressure and Temperature Resistance: Capable of operating in severe conditions with pressure ratings up to 30MPa (explosion-proof type) and specialized high-temperature versions.

6. Advanced Electrical Protection: Includes built-in protection against inverted phase, short circuits, and overloads, ensuring the electronics remain safe during installation and operation.

Applications of ZNC-FRC-S Stainless Steel Thermal Flow Switch

• Cooling System Safety: Monitoring circulating water in laser equipment and vacuum coaters to prevent "dry burning."

• Hydraulic and Lubrication Units: Detecting flow in lubricating oil lines to provide immediate pump dry-run protection.

• Industrial Furnaces: Supervising the critical cooling water flow in electric furnaces and metallurgical casting equipment.

• Automation Systems: Providing real-time flow status signals for pneumatic and hydraulic automation loops.

• Pump Protection: Serving as a flow-loss interlock to shut down pumps if the media supply is interrupted.
