OMEGA introduces the OMEGAFILM™ platinum RTD element, an element achieved by employing construction techniques similar to those used to manufacture miniature electronic integrated circuits. The result: a precision element (Pt100 for example) available in sizes considerably smaller than the head of a match. All this in a rugged, accurate, ceramic encased package! Best of all, OMEGAFILM™ elements are calibrated to the worldwide accepted DIN 43760 curve (alpha=0.00385), allowing use with standard off-the-shelf instrumentation available from OMEGA and others, both in the United States and abroad.
Accuracy and Specifications:
OMEGAFILM™ platinum RTD’s are calibrated to the internationally accepted DIN 43760 curve (alpha=0.00385) and meet 0.1% DIN standard tolerance. When you use these tables, please note that the specific operating ranges for elements vary and are listed on their specifications pages.
Applications:
Because of their small size and thin, flat packaging, OMEGAFILM™ sensors greatly extend the field of RTD applications. Series W RTD elements are thin film encased in a cylindrical ceramic package. Series W single cylindrical RTD elements (such as the W2103) lend themselves to encapsulation in short ⅛' O.D. protection tubes or shallow holes bored in a metal casing . Series W dual RTD elements ( such as the W2202) consist of 2 separate 2 wire thin film RTD elements in a cylindrical ceramic 4 wire package. Series F (such as F3101) are thin film 2 wire RTD elements on a flat ceramic base. These may be taped, cemented or embedded. To obtain accurate representative measurements, good thermal contact between the surface and the element is important. For temporary installations, a compatible temperature-rated heat- conductive compound, such as a heat sink grease can be used.

RTD Pt100 vs Thermocouple
It is not practical to compare RTDs (Pt100 and others) and thermocouples generally. However, if we compare their performance in terms of specific criteria, we can see which is best suited for specific applications. Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C.
In contrast, some thermocouples can be used at up to 2500°C. Thermocouples are generally cheaper than RTDs...
Origin Story of the RTD / Pt100
The same year (1821) that Thomas Seebeck made his discovery about thermoelectricity (Seebeck effect, see thermocouples), Sir Humphrey Davy announced that the resistivity of metals showed a marked temperature dependence. Fifty years later, Sir William Siemens proffered the use of platinum as the element in a resistance thermometer. His choice proved most propitious, as platinum is used to this day as the primary element in all high-accuracy resistance thermometers, Pt100, Pt1000 etc.
In fact, the Platinum Resistance Temperature Detector, or RTD Pt100, is used today as an interpolation standard from the oxygen point (-182.96°C) to the antimony point (630.74°C)...
What are RTD temperature sensors?
RTDs or Resistance Temperature Detectors, are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most popular RTD is the Pt100. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.
Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it...
