Thermal Flow Switch

Ah, high-precision flow

application
the switch outputs an alarm signal (such as relay action
 PNP/NPN transistor conduction
 or 4-20mA analog signal)
 triggering the system response (such as stopping equipment operation
 starting backup pumps
 etc.).
Functional characteristics
Provide high-resolution measurement in the low flow rate range
 capable of detecting small flow fluctuations and ensuring real-time feedback from the system.
There are no mechanical moving parts inside
 eliminating the risk of wear and tear
 achieving maintenance free operation
 and reducing downtime and maintenance costs.
The structure is simple
 with no mechanical delay and a typical response time of 2 seconds. It can quickly detect changes in flow and trigger actions.
Suitable for various media such as gases
 liquids
 lubricants
 etc.
 some models support monitoring of highly corrosive liquids.
Minimal obstruction to fluid flow ensures normal system operation and avoids performance degradation caused by pressure loss.
Not affected by clutter or electromagnetic interference
 it exhibits stability when monitoring viscous fluids
 magnetic fluids
 or corrosive fluids.
describe

Thermal flow switch is a flow monitoring device designed based on the principle of thermal conduction, which triggers the switch action by detecting the heat changes caused by fluid flow. It is widely used in industrial automation, mechanical equipment, air compression, refrigeration and air conditioning fields to achieve real-time monitoring and system protection of gas or liquid flow.
