OMEGA introduces its Cement-On, fast response thermocouples for fast surface temperature measurement applications in three convenient styles. Styles 1 and 2 are made from 0.013 mm (0.0005") thermocouple alloy foil by a special process where the butt welded thermocouple junction is 0.013 mm (0.0005") in thickness. Styles 1 and 2 are ﬂat, extremely low inertia construction and are an ideal means of measuring the temperature of both ﬂat and curved metals, plastic and ceramic surfaces where very fast response is desired.

OMEGA’s Cement-On Style 1 and 2 thermocouples are fabricated from ANSI “Special Limits of Error” grade thermocouple materials in K, E and T calibrations and yield accurate temperature indication when used with standard thermocouple instrumentation. Styles 1 and 2 have the fastest response. Style 3 is an economy version constructed from 0.25 mm (0.010") diameter bead welded standard limit of error thermocouple wire. It should be used where extremely fast response is not essential.

Style 2 150 mm (6") leads standard

Style 3 1 m (40") leads standard

The temperature range high limits given are greatly inﬂuenced by environmental conditions, installation method, accuracy and lifetime

requirements and may vary from the general guidelines listed in the table. Style 1 and 3 cannot be used with CC High Temperature Cement; CC Cement will break down insulation. Response time when “grounded” or “cemented” to surface: Style 1 (10 to 20 milliseconds), Style 2 (2 to 5 milliseconds), Style 3 (300 milliseconds).

The response time or “time constant” is the time required to reach 63.2% of an instantaneous temperature change. Additional length wire can be ordered for Styles 1 and 3, add cost per 300 mm (12"), for Style 2 add cost per 300 mm (12"). Ordering Example: CO1-K is a style 1, Type K thermocouple, 1 m (40") long.
