Resistance Temperature Detector (RTD) Pt100

The Pt100 temperature sensor contains a platinum resistance thermometer that changes resistance value as its temperature changes and provides accurate and reliable long-term temperature measurements. These sensors are often used in the extremely harsh environments found within Geotechnical monitoring.

The platinum element is housed inside a rugged enclosure and sealed with a special sealing material to ensure efficient thermal distribution and has IP68 waterproofing.

The principle of operation is to measure the resistance of a platinum element and in accordance with BS EN/IEC 60751:2008.
