Field of application
The RTD cable probe is easy to install and provide a high operational safety due to reliable and accurate temperature measurement in common processes. The probe is specially suited to temperature measurement in machinery, laboratory equipment and plants in gaseous or liquid medium like air, water, oil, etc. Without additional thermowell the probe sheath is directly in contact with the process medium. This enables the cable probe to detect rapid temperature changes fast and accurate.
The resistance thermometer is specially suited to temperature measurement in machinery, laboratory equipment and plants in gaseous or liquid media like air, water, oil and others.
