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 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.
