Introduction of magnetic temperature sensor

Magnetic temperature sensor is an innovative temperature measuring device, which can be easily adsorbed on various metal surfaces by built-in powerful magnets to achieve non-contact temperature monitoring. This sensor combines the precision measurement capabilities of traditional temperature sensors with the ease of magnetic installation, and is widely used in industrial equipment, HVAC systems, food processing, medical equipment and many other fields.

 

Compared to traditional temperature sensors that need to be drilled or pasted, the magnetic design does not need to damage the surface of the object under test, and the installation and disassembly process takes only a few seconds, greatly improving work efficiency and reducing installation costs.

 

Key features:

✅ Easy installation: magnetic design, ready to use, without complex fixing

✅ High precision measurement: using NTC, PT100 or thermocouple sensing elements, accuracy up to ±0.1℃

✅ Strong adaptability: IP65/IP67 protection grade, high temperature resistance, corrosion resistance

✅ Wireless optional: Some models support Bluetooth /WiFi/NB-IoT for remote monitoring

 

The magnetic temperature sensor working principle

1.Magnetic temperature sensor mainly consists of three parts:

2.Temperature sensing element (NTC/PT100/ Thermocouple)

3.Magnetic base (neodymium magnet or electromagnet, adsorption force 5-20kg)

4.Signal processing module (support 4-20mA, RS485, Modbus, etc.)

 

Work flow:

The sensor is attached to a metal surface and tightly fitted with a heat-conducting silicone pad;

 

The temperature change is transmitted to the sensing element and converted into an electrical signal;

 

The signal is amplified and output after AD conversion, and can be connected to PLC, DCS or cloud platform;

 

Five advantages of magnetic temperature sensor
