Temperature sensors are an extremely important component in many industrial processes. They make it possible to measure temperatures, control processes and protect installations from failures. Nowadays, there are different types of temperature sensors to choose from, including wired and wireless options. What are the differences between them and what benefits does each solution offer? Read this article and you will discover which version best suits your needs.
Wired temperature sensors consist of two main components: the measuring probe and the cable protecting it from external factors.
Inside the probe, there is a temperature sensor that records temperature changes in the probe's environment. This element can be made of various materials, including platinum (e.g. resistive
Pt100 and Pt1000 temperature sensors), nickel.
The probe protection cable is designed to protect the measuring element from mechanical damage and from external influences such as moisture or dust. The cable is usually made of weather-resistant plastics such as Teflon or silicone. Where the cable has to operate under extreme conditions, such as high temperatures or aggressive chemical environments, special
glass fibre or quartz fibre cables are used.

One of the biggest advantages of wired temperature sensors is their reliability. In general, wired temperature sensors are less susceptible to
interference and vibration, which means they are more stable and accurate in measuring temperature than wireless versions. In addition, wired temperature sensors are also easier to install and use.
Wired temperature sensors, however, have limited mobility, which can be a major disadvantage for some applications or even preclude their use.
Wireless temperature sensors consist of a measuring probe and a transmitting/receiving transmitting and receiving module. This probe measures the ambient temperature and transmits the signal to a wireless transmitter, which can be integrated into the sensor or separate from it. The transmitter converts the signal from the sensor into a radio signal and transmits it to the receiver. The receiver can be connected to a control device to enable real-time temperature control and monitoring.
Plug-in wireless temperature sensors such as WTRANS can find applications in the food industry
