Flat-film Pt100 Temperature Detectors

Flat-film Pt100 Temperature Detectors

We supply flat-film detectors in a wide range of sizes and tolerances to suit the application. Our standard range of detectors are manufactured with platinum-coated nickel lead wires that offer a temperature range from -70 °C to 500 °C available to IEC751 with tolerance bands Class B, Class A and 1/3DIN.

Extremely versatile, flat-film sensors are relatively cheap to manufacture and are commonly used in general-purpose applications, such as household goods, where a fast response to temperature changes is required. As a rule, flat-film sensors are less stable and have a lower temperature range than wire-wound detectors.

World-leading Manufacturer of Temperature Sensors

Flat-film and flat-wire-wound temperature detectors are available in various sizes to suit the application.

  • Film Coating

    This film is then coated with an epoxy or glass that helps protect the deposited film and also acts as a strain relief for the external lead wires.
  • Platinum Film

    Thin film elements have a sensing element that is formed by depositing a very thin layer of resistive material, normally platinum, on a ceramic substrate.

Temperature Detectors for Common Applications

The measurement of temperature is widely used across manufacturing processes and flat or thin-film detectors offer a cost-effective alternative to other types of sensors, such as ceramic wire-wound.

Pt100 detectors are used in numerous processes, such as refrigeration, heat treatment and calibration across a wide range of industrial sectors where their relative immunity to electrical noise makes them well suited for use in high-voltage equipment. Pt sensors also offer excellent stability and repeatability.
