Platinum-chip temperature sensors belong to the category of thin-film technology temperature sensors. They are produced by JUMO using the latest state-of-the-art technology under cleanroom conditions. The platinum layer acting as the active layer is applied to a ceramic body in a sputter process and subsequently given a meander-structure in a lithographic process. Fine adjustment is then carried out in a laser trimming process. To protect the probe against external influences and to provide insulation, the platinum meander is coated with a special glass layer once the adjustment is completed. The electrical connection is made by connection wires welded onto the contact surfaces. Depending on the version, the connection wires can be made of different materials, while their length and diameter can also vary to a certain extent. An additional glass layer applied to the contact surface fastens the connection wires and also acts as a tension relief.
Platinum-chip temperature sensors with the PCA design type are available ex works in various versions as Pt100, Pt500, or Pt1000 temperature sensors. Special nominal values can be manufactured upon request. Platinum chip temperature probes are also available in small sizes with high ohmic load. Their low net weight allows very fast response times. When installed as fixed units, they also provide excellent vibration resistance. The operating temperature depends on the respective version. In normal cases it ranges from -70 to +600 °C. When accepting certain nominal value offsets and/or hysteresis effects occurring within specific limits, these platinum-chip temperature sensors can also be used for temperatures well below -70 °C.
For most temperature applications required by the market, platinum-chip temperature sensors are used as an active component for temperature acquisition.
