<Whatever "It" May Be.)

~~======--
"It" may be fast changes in pre sure. Vibration. Or extreme temperature ranges. Whatever "it" may be,
the sensor must work.
At Watlow Gordon, we de ign our sensors for reliability in all types of hostile applications.
We engineered the two-element exhaust gas temperature sensor to measure
jet engine wear, power and fuel efficiency; each sensor junction rigorously te ted for
operation at temperature from -54°C to 1l05°C.
Or how about the rugged sen or construction required
to handle the vibration and high temperature of a 3000hp
diesel engine, plus waterproofing to withstand ho edown.
All of this in an open pit mining environment.
We offer fast prototyping. Our lab ervice are extensive, including metallurgical
examination, microhardnes testing and SPC. And we produce our own wire for the
ensor as emblies in our I 09002 registered wire factory.
When live are at stake. When dollars could be lost. When the project must finish
on time. You need the reliability of a Watlow Gordon ensor. Call us. We go to
extremes in temperature sensing. 1-800-WATLOW2 {1-800-928-5692}
