Aquastat temperature element
Does anyone know what type of temperature sensing element is used in a Honeywell L4006A immersion well aquastat? Thermocouple, thermistor, RTD, or something else?
Thanks,

Aquastat
It's a capillary tube filled with alcohol, no? It expands with an increase in temperature and visa versa.
Yes
Yes it is, thanks Alan. I want to get a real-time temperature measurement from the immersion well, and I didn't know if the a-stat sensor would suit the purpose. Evidently not, so the next step is to see if there's enough room in the well to slip in a thermistor along with the capillary bulb (the thermistor would be connected to a separate measuring device).
Cheers,
Mark
