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.

Note on Assembling Omega 'F' Series RTD Elements to Extension Wires: These RTD elements are made with platinum coated nickel lead wires. Since platinum does not easily wet with most soft solders, we advise that they be spot welded or silver soldered to extension wires when required.
