Although the characteristic of Thermal Sensors is highly appreciated, the way of their uses greatly affects it and can impact errors in temperature measurement, to which you are requested to pay attention.

Particulars common to Thermal Sensors

• Excessive voltage such as ESD, could damage thermal sensors.
• Water drops from condensation or impure substances that adheres between the electrode wires may cause insulation deficiency and lower the resistance value of the thermal sensors. Be aware when using this product.
• Avoid applying thermal shocks with large temperature difference in order to maintain the accuracy of the thermistor.
• Some of the thermal sensors use special temperature sensing films. Contact us if the sensors are constantly operated under high temperature environment.

Platinum Thin-Film Thermal Sensors

• Welding is recommended to connect the heat resistant leads of element of SDT101B, SDT310P, SDT310MTM, SDT310AP, SDT310HCTP and SDT310VASP since they have heat resistant lead wires. Select the flux for stainless-steel when soldering. Wash the flux with hot water after the soldering to remove the residues completely.
• The 3-wire system or 4-wire system is recommended to measure high precision temperatures for both SDT101 and SDT310 series.
• When molded or placed in a metal tube cover filled with resin, the resistance value may change depending on the resins used.
