The RTD probe is easy to install and measures temperature reliably and accurately in general process applications, providing high operational safety. The probe is particularly suitable for measuring gaseous and liquid media such as air, water and oil in machinery, laboratory instruments and plants. Without an additional thermowell, the probe housing is in direct contact with the process medium and can detect instantaneous temperature changes quickly and accurately.
