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 0.0005" thermocouple alloy foil by a special
process where the butt welded thermocouple junction is 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 0.010" diameter bead welded standard limit of error thermocouple wire. It should be used where
extremely fast response is not essential.
Cement-On Style 1 thermocouples are the easiest to install. The foil sensor is embedded between two
paper thin, glass reinforced high temperature polymer laminates which both support and electrically insulate
the foil section as well as provide a flat surface for cementing. The polymer/glass laminate, in general,
determines the maximum temperature of the construction which is 260°C (500°F) continuous and up
to 370°C (698°F) for short duration. Each Style 1 unit includes 1m (40")of glass braid insulated 30 gage
thermocouple wire which is bonded to the foil and strain relieved by laminate. An application instruction
sheet accompanies each packaged Cement-On type thermocouples.

OMEGA Cement-On Style 2 thermocouples are recommended where extremely fast surface
temperature measurement response time is a requirement. Intimate thermal coupling for this style is
achieved by directly bonding the foil junction area to the surface to be measured. For ease of handling, the
foil leads come fastened to a polyimide film frame which is tough, flexible, dimensional, stable material
rated for 260°C (500°F) continuous service. During application, the foil thermocouple can be peeled from
the frame or released by the application of heat. As an alternate, portions of the frame may be cut away
by scissor or knife.
The 150 mm (6") uninsulated foil leads are of 0.05 mm (.002") material and thus are fragile and should be
handled with care during installation. NOTE: It is imperative that the leads be electrically insulated from
each other as well as being mechanically supported. This can be achieved, for example, by laying and
brushing the leads into a layer of insulating cement or epoxy. Before doing this on electrically conductive
surfaces, it is best to lay down and let dry, a thin layer of the cement to insure that the leads are insulated
from the surface. Insulated thermocouple lead wire can be bonded to the foil leads by silver soldering, or
resistance welding. Thirty gage, or smaller lead wire is suggested. An application instruction sheet
accompanies each package of thermocouples.
Cementing of the junction and lead may be achieved by using OMEGA® CC high temperature cement for
temperatures above 260°C (500°F); OMEGABOND® OB-101 or OB-200 epoxies for temperatures below
260°C (500°F). Please note more care is required to install the Style 2 than Style 1 or 3. It is suggested that
at least one additional unit be ordered as some experimentation may be necessary to learn the
technique of application for these thermocouples.

Style 3 thermocouples are constructed of 30 gage (0.010") diameter "Standard Limits of Error" wire.
The welded bead thermocouple is embedded in a paper-thin laminate intended for surface applications
by bonding with added adhesive. Color-coded, glass braid insulated 1m (40") leads are supplied. Style
3 probes can be used over the range of -190 to 370°C (-310 to 698°F) depending on the adhesive or cement
used, the time of exposure and the environment.

Note: 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 $6.00 per 300 mm (12"), for Style 2 add $10.00 per 300 mm (12")
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.
