Accurate temperature control is critical in industrial systems. Our professional-grade thermocouples deliver reliable, fast-response temperature measurement for manufacturing, heating systems, furnaces, and industrial machinery across the UK.
Whether you require a K type thermocouple or other configurations, WMC Online supplies high-quality sensors engineered for durability and precision.
What Does a Thermocouple Do?
Simply put, what does a thermocouple do?
It measures temperature by generating a small voltage when two different metals are joined and exposed to heat. This voltage correlates directly to temperature, allowing precise monitoring in industrial environments.
How Does a Thermocouple Work?
If you’re wondering how does a thermocouple work, the process is simple yet powerful:
-
Two dissimilar metals are joined at one end
-
Heat creates a voltage difference (Seebeck effect)
-
The voltage is interpreted as temperature
This design makes thermocouples highly resistant to vibration, pressure, and extreme temperatures — ideal for demanding UK industrial applications.
Thermocouple Types Available
There are several thermocouple types, each designed for specific temperature ranges and environments. The most widely used is the K type thermocouple, known for:
-
Wide temperature range
-
Strong oxidation resistance
-
Excellent reliability
-
Cost-effective performance
Our thermocouples are suitable for furnaces, boilers, gas appliances, CNC systems, and process control equipment.
How to Test a Thermocouple
Need to know how to test a thermocouple?
-
Use a multimeter set to millivolts
-
Apply heat to the sensor tip
-
Check for voltage change
-
Compare reading with standard temperature charts
If voltage output is unstable or absent, replacement is recommended.
