Thermal flow switch, as an efficient and accurate flow monitoring device, plays a crucial role in the field of industrial automation control. Its unique heat conduction principle and advanced technological design make it perform outstandingly in various fluid systems, becoming a key component for ensuring system safety and improving operational efficiency.

Core characteristics of thermal flow switch

Wide setting range and high precisionThe thermal flow switch has a wide range of flow settings, and the water flow setting range is1~150cm/sThe oil flow rate is3~300cm/sThe air flow rate is as high as20~3m/sIt can meet the flow monitoring needs of different media and working conditions. Meanwhile, its high-precision measurement capability ensures accurate capture and feedback of flow signals, providing reliable basis for system control.

Diversified signal output: This device supports multiple signal output methods, includingPNPTheNPNRelay, normally open+Normally closed（SPDT）And4~20mA(Three wire system), which can flexibly connect to various control systems to achieve remote monitoring and automated control of traffic.

Strong environmental adaptability: Thermal flow switches have good environmental adaptability and a wide range of medium temperatures-20~80℃The ambient temperature also covers-20~80℃Capable of stable operation under extreme temperature conditions. In addition, itIP67The protection level ensures the waterproof and dustproof ability of the equipment in harsh environments, extending its service life.

Fast response and initialization: The device has a short response time, with typical values of only2In seconds, it can quickly capture changes in traffic and respond accordingly. Meanwhile, approximately8The initialization time of seconds enables the device to quickly enter the working state after startup, improving the overall response speed of the system.

The Wide Application of Thermal Flow Switches

Cooling cycle system protection: In the cooling cycle system, the thermal flow switch can monitor the flow rate of cooling water in real time. When the flow rate is lower than the set value, an alarm signal is issued in a timely manner to prevent equipment from overheating and damage due to insufficient cooling, ensuring the stable operation of the system.

Lubrication system monitoring: In the lubrication system, this equipment can monitor the flow of lubricating oil to ensure the normal operation of the lubrication system, avoid mechanical wear and failure caused by the interruption of lubricating oil flow, and extend the service life of the equipment.

Pump idle protection: The thermal flow switch can also be used for pump idle protection. When the inlet flow of the pump is insufficient, the equipment will trigger an alarm and stop the operation of the pump, preventing damage to the pump due to idle and reducing maintenance costs and downtime.

Thermal flow switches have become an important part of industrial automation control due to their unique characteristics and wide application fields.
