Features
- Being standardized by JIS, this is a reliable temperature sensor that uses the characteristics of platinum (Pt), which has a long heat life and shows stable electrical resistance against temperature change.
- A platinum resistance thermometer sensor measures the resistance that changes according to the temperature when low current is applied to the platinum wire or thin film, the resistance of which is kept constant (usually 100Ω), and then converts the measured resistance to a temperature value.
- To prevent the lead wire resistance from being added, it usually adopts a three-wire design.

Precautions when using this product
- When tightening set screws (hexagon socket set screws), be careful not to tighten them so tightly that the internal components of the product are damaged or deformed.
- If the sheath needs to be bent when it is used, consult our sales representative when placing an order.
