CO4-K

Ultrafast Surface Foil Thermocouples

GENERAL DESCRIPTION

OMEGA’s Thermocouples have been designed and CO4-K fast Surface Foil Ultra
fabricated to work in harsh environments where response time characteristics for
the process are required to be measured in the order of a few milliseconds.

T Thermocouple Junction Foil Thickness he provides for Low Mass & 0.00 ”2
Thermal Inertia. Using such a delicate foil on the measurement surface could bare
have resulted in a lot of installation losses. We protect the sensing junction with a
polymer encapsulation to offer a yet sensor -flexible toughplug and play quick to
install with accurate and repeatable measurements every time.

SECTION INSTALLATION 2 :

2.1 Using Adhesives

1. Thermocouples can be bonded Ultrafast Response Surface Foil
to most surfaces using Epoxy Adhesives 100, 101, and 200. OB
Each epoxy has different temperature ratings, cure
characteristics, and thermal conductivity factors. Refer to the
Omega emperature easurement Handbook for more T M
information on EpoxiesOB

2. When using epoxies, be sure that the surfaces to be bonded are
clean. Use an appropriate solvent or detergent for cleaning.

3. For temperature above 500 F, use Omega High temperature
Cement

4. For applications under 260 C (500 F), use 200 Epoxy. 200
is a specially formulated epoxy with high thermal conductivity, To
retain the fast speed of response, use a thin layer of adhesive

2.2 Installation Tips.

The bonding process of the Ultrafast Surface Thermocouple to the
measurement surface depends on a number of parameters like operating
temperature, mounting surface etc. , adhesive to be used

For optimum response time , all air gaps between sensor and
measurement surface have to be eliminated so that the sensor polymer
matrix is always in contact with the measurement surface.

STEP I : P with a coarse olish the bonding site
sandpaper in a considerably wider area than
the thermocouple film size. paint, rust Remove
and plating with a grinder or sand blast. Then,
polish with sandpaper.

STEP II : /Using an absorbent cotton gauze
dipped in a highly volatile solvent such as
acetone, strongly wipe the bonding site in a
single direction to remove oils and fats. Please
Note reciprocated wiping does not clean the
surface.

STEP III : Place the Ultrafast Thermocouple
on the clean surface and anchor / clamp the
leads downstream from the sensor measuring
junction

STEP IV : Adhesive / Cement Spread the
Paste uniformly 4-K Thermocouple over CO
such that the sensor is sandwiched between
the Adhesive and the measurement surface.
