HOTTEMP – RTD PTC101
Resistance Temperature Detectors (RTD) Sensor Bulb
All types of RTD (Resistance Temperature Detector) sensor that are made from Platinum. The Pt100 sensor has a resistance of 100 ohms at 0°C and is by far the most common type of RTD sensor. The Pt50 sensor has a resistance of 50 ohms at 0°C and the Pt1000 has 1000 ohms resistance at 0°C. These sensors are normally fitted into some type of protective sheath or mounting to form a probe, and these are commonly referred as RTD element.
The Thin-Film Type platinum is deposited on a ceramic substrate, than coated with glass. The sensitive element is extended by radial leads. The Thin-Film sensor can be integrated in different designs of probes for dry environments only.
The Ceramic Wire Wounded Type platinum elements are made by placing a coiled platinum wire into a ceramic core and sealing the ends off with glass. They are suitable for extremely low or high temperatures, and are tolerant of thermal shocks. They offer limited vibration resistance (depending on mounting method) and should be used in dry environments only.
