What can you expect from thermoelectric sensors?
A thermocouple as a thermoelectric sensor ensures precise measurement of temperatures. Typically, a thermocouple consists of two different types of metal that are connected to each other at their ends. The other two ends connect to the measuring instrument, which has the ability to process the outgoing signal. The diverse design shapes of thermocouples allow them to be used over a wide range of temperature conditions. One of the most widely used types of thermocouples is type K, which covers a wide temperature range from -200 to 1,250 degrees Celsius.
The conversion of electrical voltage to measure temperature changes is based on the Seebeck effect, which states that a voltage is generated when there is a temperature difference between two different metals that are connected at their ends, as mentioned earlier. The voltage generated is proportional to the temperature difference, which allows a direct and effective method of temperature monitoring and control.
What are the advantages of thermocouples?
Intelligent thermocouples offer numerous advantages that you can utilize for your workflows. Their high precision makes them suitable for many demanding environments, so you don't have to compromise.
All the advantages of thermocouples at a glance:
1. High temperature resistance: thermocouples can measure very high temperatures, typically up to 2,500 degrees Celsius, making them ideal for applications such as industrial furnaces, gas turbines and other high temperature environments.
2. Fast response time: Thermocouples react quickly to temperature changes. This enables precise and prompt monitoring of temperature changes in processes where fast response times are required.
3. Wide temperature range: In addition to the ability to measure high temperatures, thermocouples can also be used at very low temperatures, which makes them versatile.
4. Easy handling and robustness: thermocouples are robust and durable due to their simple design. They are made of two different metals, are easy to install and require little maintenance.
5. Cost-effective: Compared to other temperature sensors, thermocouples are often less expensive, especially considering their longevity and robustness.
6. Direct temperature measurement: Thermocouples measure temperatures directly and do not rely on conversions or complex sensor technologies. As a result, they offer high accuracy without the need for frequent calibrations.
7. Flexibility in design: The wires of a thermocouple can be long and flexible, which facilitates installation in complex industrial systems.
How does a thermocouple work as a thermoelectric sensor?
If two different metals are connected at their ends and one of the connection points is heated, a current is generated in this thermoelectric circuit. If the circuit is interrupted, the resulting thermoelectric voltage reflects the temperature at this connection point.
Thermocouples consist of various metal combinations, classified into types such as K, J, T, E and N made of base metals and R, S, B, C and G for high temperatures made of precious metals. Each type has a specific temperature range and is suitable for different environments. However, the maximum temperature that a thermocouple can withstand is often limited by the diameter of the wire. Type K is ideal for general applications due to its wide temperature range and low price.
Where are thermocouples used?
When it comes to temperature measurements with high demands, thermocouples demonstratetheir qualities in a wide range of applications:
- Process industry: Monitoring and control of industrial ovens, boilers and heating systems.
- Energy generation: Temperature measurement in power plants to ensure efficiency and safety.
- Food processing: Ensure correct cooking and freezing temperatures.
- Plastics industry: In plastics processing, e.g. injection molding or extrusion, thermocouples are used to precisely monitor and control the temperature of the melt and the tools.
- Metal processing: Temperature monitoring in heat treatment processes such as hardening, forging and soldering to achieve the desired material properties.
- Packaging industry: Control of sealing processes to ensure the integrity of packaging.
- Semiconductor industry: Precise temperature control to maintain process specifications and product purity.
How do I find the right thermocouple?
Before you decide on a thermoelectric sensor, you should make sure that it meets your needs. It is important that the model fits seamlessly into your processes and supports your routines. We have compiled some of the most important selection criteria for thermocouples below:
- Type of thermocouple: Selection of the correct thermocouple type (e.g. type K, J, T) based on the required temperature range and environment.
- Measuring range: Ensure that the measuring range of the thermocouple is suitable for the specific application.
- Accuracy class: Adaptation of the accuracy requirements depending on the required measuring precision.
- Material and design: Requirements depend on chemical resistance as well as mechanical and thermal conditions.
- Protection class: Suitable protective housing or protective tubes, especially for harsh industrial environments.
- Connection options: Selection of plug or cable connections according to the intended installation.
What are the optimum installation conditions for thermoelectric sensors?
To ensure that thermocouples can work to their full efficiency, you should ensure the right conditions during installation.
These include
- Correct installation location: Thermocouples should be placed where they can measure the actual temperature of the medium without external influences.
- Minimal interference: Avoid electrical and magnetic interference that could affect the measuring accuracy.
- Easy accessibility: Thermocouples should be easily accessible for maintenance work.
- Environmental protection: If required, the thermocouple should be installed in low-noise and clean environments or using protective covers.
