General Purpose Thermocouple Probes
with Flexible Extensions (One-Piece Construction)
A8D Series
The construction of this thermocouple is a one piece design which does not utilize any transition fitting. Advantages of this construction are no splices from thermocouple to lead wire and no transition adaptors having a diameter greater than the thermocouple sheath. Units can therefore be mounted from the inside out of a chamber, pushed into a drilled hole, etc.
- Various adjustable compression fittings and mounting bushings are available for these units.
- Both standard size and miniature plugs and jacks are also available.
NOTES:
- Duplex units are available on various units, contact factory with your particular requirement.
- Lead lengths other than 36 inches, and lead wire insulations other than fiberglass are available.
- PFA Tefton% encapsulation - good to 450°F, can be added to any probe.
If you require that unit can be bent, contact factory for more information.
Thermocouple calibration type N is available in all sizes.
