Section 1 General Description
Style 1 & Style 1-B "Cement-On" ermocouples are made from 0.005
in thermocouple embedded between two layers of high tempreture
polymer / glass laminate. is laminate generally limits the maximum
temperature for construction to 260° (500°F) continuous, 370°C
(698°F) for short duration. e insulated lead wire is silicone impregnated glass braid. e sislicone impregration provides abrasion resistance, but is destroyed at approximately 205°(400° F). e glass braid
provides electrical insulation to 480°C (896°F).
Style 1-B "Cement On" e thin sensor (0.008") is embedded between
two thin, high-temperature polymer laminates which both support and
electrically insulate the foil section as well as provide a at surface for
cementing. e polymer 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 gauge thermocouple wire
which is bonded to the foil and strain relieved by laminate. An application instruction sheet accompanies each packaged Cement-On type
thermocouples.
Style II "Cement-On" sensors are made from .0005 "foil with .002"
leads. e foil leads are fastened to a polyimide lm frame which is a
tough, exible, dimensionally stable material rated for 260°C (500°F)
continuous service.
Style III "Cement-On's" are made from 30 gauge (0.010") diameter
thermocouple wire. e thermocouple is bead welded and embedded
between two layers Of paper thin polyimide lm. is lm is rated up
to 370°C (698°F). e insulated lead Wire is silicone impregnated glass
braid With the same qualities listed above for Style I. e table on the
following page lists the maximum temperature for the three styles of
thermocouples.

Section 2 Installation
2.1 Using Adhesives
1.
"Cement-OR" ermocouples can be bonded to most surfaces using
OB Epoxy Adhesives 100, 101, and 200. Each epoxy has dierent
temperature ratings, cure characteristics, and thermal conductivity
factors. Refer to the Omega Temperature Measurement Handbook
for more information on OB Epoxies.
When using epoxies, be sure that the surfaces to be bonded are
2.
clean. Use an appropriate solvent or detergent for cleaning.
For temperatures above 5CO°F, use Omega CC High Temperature
3.
Cement to bond Style II "Cement-On" ermocouples to most
metals and ceramics. CC Cement is not recommended for Style I
and Style III "Cement-OR's".
4.
For applications under 26°C (500°F), use OB 200 Epoxy.
OB 200 is a specially formulated epoxy with high thermal conductiv-
5.
ity. To retain the fast speed of response, use a thin layer of adhesive.

2.2 Installation Tips
Style I: Use a clamp to strain relief the lead wire downstream from
the sensor
Style I
Style I-B
Style II
1.
During application, the foil thermocouple can either be peeled from
the frame or released by applying heat.
2.
e .002" foil leads are uninsulated. Before working on
electrically conductive surfaces, lay down a thin layer of
insulating Omega CC
Cement or OB Epoxy and
let it dry. is ensures that
the leads are fully insulated
from the surface. en
apply a thin layer of the
cement or epoxy to the
surface, and brush the leads
into it (use this step alone
for non-conductive surfaces).
3.
Bond insulated thermocouple lead wire to the foil leads by silver
soldering or resistance welding. Use thirty gauge insulated thermocouple lead wire such as GG- (K or E or T)-30. Refer to the
Omega Temperature Measurement Handbook for information on
thermocouple wire.
Install Type T (Copper/Constantan) foil junction by carefully
4.
pressing into a owed thin layer Of so solder.
5.
Type K (Chromega® / Alomega™) and Type E (Chromega®/Constantan) will not bond properly with so solder. However, with
care and skill, a bond can be made using a low temperature silver
solder of less than IO00°F.
Style III: ese "Cement-On" lhermocouples may be bonded to most
surfaces using the same technique as for Style L
