Measuring resistors in thin film technology

Thin-film temperature sensors are based on an Al2O3 substrate with a fine platinum layer applied to it. This layer is precisely structured using laser or stencil techniques to achieve the desired nominal resistance. To protect it from external influences, the platinum layer is covered with a passivation layer. The connecting wires are typically made of Ag5Pd (silver-palladium), which is reinforced with a special locking layer for additional tensile strength. Thin-film sensors are designed for use in temperature ranges from -50°C to +400°C (special versions for -200°C to +1000°C are available).
The measuring resistors offered here meet the requirements of DIN EN 60751 in terms of base values and tolerances. They feature fast response times, compact designs, and affordable prices. On request, versions for higher temperatures, increased accuracy, or as SMD components are also available.
Most popular thin-film measuring resistors:
- The listed prices apply to measuring resistors with Ag5Pd connecting wires. For different designs or applications with higher temperatures, please contact us.
- By default, we offer tolerance class F 0.3 according to DIN EN 60751 (±0.3°C). Additional tolerance classes (e.g., class F 0.15) are available upon request. All values are specified for 0°C.
- Our measuring resistors are subject to minimal geometric manufacturing tolerances. If there are space constraints in your design, we are happy to provide the exact dimensions.
