Thin film RTD temperature sensors

Thin film temperature sensors

High vibration environments can cause inaccurate temperature measurement as well as sensor failure. It is with this in mind, that Kamet offers a range of robust thin film sensors which are specifically designed for these kinds of challenging applications. These RTD temperature sensors are furthermore:

  • Cost-effective
  • Easy to interface with instrumentation
  • Stable and accurate  over a wide temperature range varying from -200 to +800°C
  • Available in a variety of size, shape and tolerance options
  • Fast in response time

What is a thin film RTD sensor?

RTD stands for Resistance Temperature Detector. An RTD measures temperature by the change in resistance values of metal during heating or cooling . ‘Thin film’ refers to the unique design of a series of sensors consisting of an ultra-thin layer of platinum on a ceramic substrate. Passivation is achieved through a glass micro-coating, which also makes this a rugged sensor with excellent resistance to (thermal) shock, vibration and environmental influences.

Other important design advantages of a thin film:

  • Less metal is required. This makes thin film RTD sensors a  cost-effective solution for accurate measurement.
  • The flat profile and small size mean the sensor will fit in many instrumentation and industrial control applications.
  • The lead wires allow for easy  interfacing with instrumentation. These can be attached via crimping, brazing, welding or soldering.
  • Different resistance levels mean a wide range in temperature measurement.
  • Thin film sensors have a resistance of Pt50 (50 ohms), Pt100 (100 ohms), Pt500  (500 ohms) or Pt1000 (1000 ohms) at 0°C. This range makes them very versatile in application.

Thin film RTD sensors allow temperature measurement in the most demanding of applications making them the perfect match for most industries.

Usage of RTD sensors in industrial applications

Thin film RTD sensors come in a variety of sizes, shapes and tolerance options including DIN Class A and DIN Class B variants. The different resistance levels: Pt50; Pt100; Pt500;  Pt1000  mean they fit a wide range in temperature measurement needs.

This design and temperature versatility combined with ruggedness and durability makes thin film sensors the ideal RTD sensor for many industrial applications including:

  • refining and petrochemical industries
  • analytical and medical equipment
  • aerospace technology
  • automotive industry
  • power and energy generation
  • HVAC (Heating, Ventilation and Air Conditioning)
  • Instrumentation

The thin film sensors differ primarily in operating temperature range. The min/max operating temperature of your application must fall within the operating range specified for the part.
