PT-100 platinum resistance low-temperature sensor

PT-100 platinum resistance low-temperature sensor

The wound PT-100 platinum resistance sensor adopts a ceramic or glass tube packaging method, featuring a solid and stable structure and a wide temperature measurement range. All platinum resistance sensors we provide comply with the IEC751 industrial standard, with a measurement temperature range from 14K to 1073K. For the convenience of customers' installation and use, we can provide unique ARB packaging methods and brazing process leads. Platinum resistance sensors have a constant sensitivity (dR/dT) within the measurement temperature range, good interchangeability, high stability compared to diode sensors, and are less prone to damage. In low-temperature environments above 40K, it is less affected by magnetic fields and can be applied in temperature environments with magnetic fields.
