This spring-loaded thermocouple is designed for threaded blind-hole measurements, or for surfaces subject to vibration/oscillation, or any application where positive contact for good measurement is required. The sensing tip of this device consists of a thin ribbon thermocouple element overlapped onto a phenolic rod. This rod is spring loaded within the threaded stainless steel thermowell body. Thus, the sensing tip can be depressed up to 1/8 inch while it continuously maintains good thermal contact to the object whose temperature is being measured. The combination of the thin ribbon thermocouple and low thermal conductivity of the phenolic rod yield response times of less than 200 milliseconds. This combination also provides temperature measurement without conduction errors and thus the true temperature of the test item is monitored.
Ordering Information - remember to specify thermocouple type. Example: B9-1-K
All units come with a Delrin locking-element (slug) which when used, resists loosening due to vibration. However, this limits the upper temperature limit to 300 F. The Delrin slug can easily be removed with a pair of pliers, thus increasing the upper temperature limit to 450 F, there are several other techniques one can use to resist vibration, contact the factory to discuss these options. Also, if higher temperatures are required, please contact the factory with your particular requirement. NOTES:
* When ordering, specify thermocouple calibration with model number.
