PT100 3-wire temperature probe

PT100 3-wire temperature probe is a type of RTD platinum probe used to measure temperatures up to 250°C. This type of probe can be used with RTD click.

RTD sensors are basically thermosensitive resistors – materials that change the resistance depending on their temperature. In this case, the resistor is a small strip of platinum with a resistance of 100Ω at 0°C – that is why it is called PT100.

• Temperature: max. 250⁰ Celsius
• 3-Wire
• Length: 1m (100cm, 3.37 inches)
• Grade: 2B
• Tolerance: 0.5

Why use an RTD type of sensor?

• A wide temperature range 
• Precision and accuracy 
• Long-term stability

For many years, these type of sensors have been used in industrial and laboratory conditions since they are considered to be more accurate and stable than most NTC/PTC thermistors. Also, platinum is an excellent choice since they are very stable and reusable, and are resistant to corrosion or oxidation.
