Dayton 36GL15 Thermocouple Probe Type K
The Dayton 36GL15 is a Type K thermocouple probe designed for industrial temperature measurement across air, gas, and liquid applications. It features an ungrounded junction and a standard plug for straightforward connection to compatible instrumentation. The probe dimensions are 1/8 inch by 6 inches with a 6 inch cable length, making it suitable for technicians and engineers who need reliable thermal data in process environments.
Thermals Noise And Power Draw
This passive sensor generates no heat, produces no audible noise, and draws no electrical power during operation. Its measurement range spans from -325 degrees Fahrenheit to 2280 degrees Fahrenheit, or -200 degrees Celsius to 1250 degrees Celsius. The ungrounded design helps reduce electrical interference, supporting stable readings in electrically noisy industrial settings without adding thermal load to the system.
Upgrade Path And Fit
The probe replaces worn or damaged Type K sensors that use a standard plug and 1/8 inch diameter sheath in similar process fittings. It is not suited for applications requiring a different thermocouple type, a miniature connector, or a sheath diameter other than 1/8 inch. The jump is worthwhile when the existing probe has drifted out of calibration or when the ungrounded junction is needed to eliminate ground-loop errors.

Questions about this item
How do I install the probe with the 1/4 in MNPT and 1/8 in MNPT fittings, and what step is often missed?
Thread the correct fitting into the matching port, tighten with a wrench on the hex flats, then plug the standard connector into the meter; the step often missed is using PTFE tape or paste on the NPT threads to prevent leaks in air, gas or liquid service.
What maintenance or replacement will this Type K probe need over time?
The ungrounded junction resists drift longer than grounded types, but the probe should be replaced once calibration checks show readings outside your process tolerance or if the sheath shows corrosion, pitting or mechanical damage from the media.
What limit appears first during sustained use at high temperature?
The 1,250 °C / 2,280 °F upper rating of the Type K thermocouple is the first limit reached; continuous operation near this temperature accelerates metallurgical drift and sheath degradation faster than the 6 in cable or standard plug.
