What does a temperature measuring device offer?
A temperature sensor is one of the most important tools when it comes to capturing temperature differences and converting them into a measurable signal. If a temperature measuring device has recorded and output a temperature, you can then process the signal further or immediately To control processes use. Depending on which area of application you need a temperature sensor, this comes with different measurement principles Therefore, be it the resistance or thermal electricity principle.
Which sensors of a temperature sensor are the right ones?
Temperature sensors differ in Active temperature sensors and passive temperature sensor. In the case of the first -mentioned, sensors are actively determined in your environment. This variant is particularly in the Industrial and private control technology used. The output signal is output as a current signal (4-20 MA) or as a voltage signal (0-10 V). In the sensor itself, a temperature transfer is embedded that converts the recorded resistance values into the linear output signal.
A passive temperature sensor needs one Additional energy source, to grasp changed temperatures in the area. Such a measuring device of the temperature with passive sensors can bring a resistant, capacitive and inductive sensor. Outside temperature sensor are an example of resistive sensors. Capacitive sensor depend on electrical capacities, while inductive sensors create an electromagnetic field.
Record the temperature sensor, depending on the option, temperatures or need one Contact point. The best known include thermo elements, resistance thermometers (RTD) and thermistors.
Thermo elements are made up of two wires of different metals or alloys that are connected at one end. They work according to the principle of Comparative measurement And have a measuring point and a reference site. If the temperature at the measuring point differs from that at the reference site, there is an electrical voltage between the two wires, which is caused by the Seebeck effect is created. Afterwards, the value recorded can be interpreted using the temperature sensor using a measuring instrument and converted into a temperature.
Resistance thermometer As a temperature sensor, often also referred to as RTDS (Resistance Temperate Detector), the temperature measured by using the change in the electrical resistance of a metal conductor (often platinum) with the temperature. The resistance of the platinum wire increases linearly with the temperature. The best known RTDs are PT100 and PT1000, in which the resistance at 0 ° C is exactly 100 ohms. RTDs are special for their High accuracy and stability known. However, they usually react more slowly to temperature changes than thermo elements.
In contrast to RTDS, which consist of metals, are Thermistors Under the temperature sensors as Semiconductor sensors known. Your change in resistance with the temperature is not very linear, which gives you a high sensitivity in tight temperature ranges. There are two main types of thermistors: PTC (positive temperature coefficient), the resistance of which increases with increasing temperature, and NTC (negative temperatures coefficient), the resistance of which decreases with increasing temperature. NTC thermistors are the most frequently used and are characterized by a quick response time and high accuracy via limited temperature ranges. They can often be found in household appliances, medical devices and electronic devices, where they are used for temperature control and monitoring. Since the temperature sensors can only monitor a limited area, they are designed for very narrow temperature ranges.
