Standard Thermal Flow Switch

Overview of Standard Thermal Flow Switch

The Standard Thermal Flow Switch is an electronic switch for monitoring and controlling the flow of liquid, gas, or oil media in industrial pipelines.

• What is it? Flow switches are primarily installed in-line or inserted into water, gas, oil, and other media pipelines to monitor the flow rate within the system. When the flow is higher or lower than a set point, an alarm signal is triggered to the control unit, helping to avoid or reduce the risk of the host equipment "dry burning."

• Principles of Operation: Based on the thermal principle, the sealed probe contains two resistors, one is heated as the detection resistance, and the other is unheated as the reference resistance. When the medium flows, heat from the heated resistor is carried away, changing its resistance value. The difference between the two resistance values is then used as the basis for judging the flow rate.

• Main Application Field: Mainly used in fluid cooling systems and hydraulic/pneumatic systems. This includes: water-cooled welding machines, laser equipment cooling systems, vacuum coating machines, electric furnaces, polysilicon ingot casting furnaces, and other applications where the circulation of water, cutting fluids, or lubricating oil must be monitored for cut-offs, as well as pump idling protection.

• Key Characteristics: The biggest feature is having no moving parts, resulting in maintenance-free operation and high immunity to interference. It offers multiple mounting options (plug-in, in-line), is suitable for various fluid media like water, oil, and gas, and can withstand high pressure and high-temperature conditions.

Features of Standard Thermal Flow Switch

Here is a summary of the main selling points of the Standard Thermal Flow Switch:

1. Maintenance-Free Design: The product has no moving parts, fundamentally eliminating the risk of mechanical wear and failure, ensuring long-term, maintenance-free operation. 

2. Wide Media Compatibility: Suitable for monitoring the flow of various fluid media, including water, oil, and gas, offering a wide range of applications.

3. Versatile Signal Output: Provides multiple signal output options, including Relay, PNP, and NPN, facilitating easy integration with various PLCs or control systems.

4. High Pressure and Temperature Resistance: Accommodates severe operating conditions with high pressure resistance (standard and explosion-proof types) and wide medium temperature tolerance.

5. Flexible Mounting: Offers multiple installation options, including plug-in and in-line (threaded or flanged connections), meeting diverse site requirements. 

6. High Reliability: Features multiple electrical protections, including inverted phase, short circuit, and overload protection, with a high protection class, ensuring long-term stable operation.

Applications of Standard Thermal Flow Switch

The Standard Thermal Flow Switch is widely used in applications that require precise monitoring of fluid flow status and the protection of critical equipment:

• Cooling System Protection: Monitoring circulating water in equipment like water-cooled welding machines, laser equipment, and vacuum coating machines for cut-offs, preventing equipment overheating ("dry burning"). 

• Hydraulic and Lubrication Systems: Monitoring flow in cutting fluid and lubricating oil lines and providing pump dry-run protection.

• Industrial Furnaces: Monitoring the cooling system flow for electric furnaces and polysilicon ingot casting furnaces.

• Automation Systems: Used in pneumatic and hydraulic systems to monitor fluid status and provide alarm signals.
