What does a temperature measuring device offer?

A temperature sensor is one of the most important tools when it comes to detecting temperature differences and converting them into a measurable signal. Once a temperature measuring device has recorded and output a temperature, you can then process the signal further or immediately for the control of processes use. Depending on the area of application for which you require a temperature sensor, it comes with different measuring principles Therefore, be it the resistance or thermoelectricity principle.

Which temperature sensors are the right ones?

Temperature sensors differ in Active temperature sensors and Passive temperature sensors. With the former, sensors actively detect temperature-related changes in their environment themselves. This variant is mainly used in the industrial and private control technology is used. The output signal is provided as a current signal (4-20 mA) or as a voltage signal (0-10 V). A temperature transmitter is embedded in the sensor itself, which converts the measured resistance values into the linear output signal.

A passive temperature sensor requires a Additional energy sourceto detect changing temperatures in the environment. Such a temperature measuring device with passive sensors can have a resistive, capacitive and inductive sensor. Outdoor temperature sensor are an example of resistive sensors. Capacitive sensors are dependent on electrical capacitance, while inductive sensors generate an electromagnetic field.

Depending on the option, temperature sensors record temperatures without contact or require a Contact point. The best known include thermocouples, resistance thermometers (RTD) and thermistors.

Thermocouples are made up of two wires of different metals or alloys that are joined together at one end. They function according to the principle of comparative measurement and have a measuring point and a reference point for this purpose. If the temperature at the measuring point differs from the temperature at the reference point, an electrical voltage is generated between the two wires, which is measured by the Seebeck effect is generated. The recorded value can then be interpreted via the temperature sensor using a measuring instrument and converted into a temperature.

Resistance thermometer Temperature sensors, often referred to as RTDs (Resistance Temperature Detectors), measure temperature by using the change in electrical resistance of a metal conductor (often platinum) with temperature. The resistance of the platinum wire increases linearly with temperature. The best-known RTDs are Pt100 and Pt1000, where the resistance at 0 °C is exactly 100 ohms. RTDs are particularly known for their High accuracy and stability known. However, they generally react more slowly to temperature changes than thermocouples.

In contrast to RTDs, which are made of metals Thermistors among the temperature sensors as Semiconductor sensors known. Their resistance change with temperature is strongly non-linear, which gives them a high sensitivity in narrow temperature ranges. There are two main types of thermistors: PTC (Positive Temperature Coefficient), whose resistance increases with increasing temperature, and NTC (Negative Temperature Coefficient), whose resistance decreases with increasing temperature. NTC thermistors are the most commonly used and are characterized by a Fast response time and High accuracy over limited temperature ranges. They are often found in household appliances, medical equipment and electronic devices, where they are used for temperature control and monitoring. As the temperature sensors can only monitor a limited range, they are designed for very narrow temperature ranges.
