Description

This particular thermowell is 4" long with a 2" TC flange welded to the open end of the tube. The tube's ID accepts probes up to 1/4" in diameter. Don't forget, 2" TC measure 2.5" actual diameter.

Thermowells are devices that install into your vessels (or within your threaded plumbing) that allow a thermometer, digital thermometer probe, or temperature controller sensor to be inserted but kept isolated from the liquid the thermowell is immersed in.

We've sold hundreds of the probe compression fittings for doing a similar thing, but several customers asked us for a version that would allow the removal of the probe without losing the liquid in the vessel. This is also important if you're using a temp probe that is not already waterproof or made of food grade materials. You can get these in either 1/4" or 1/2" NPT, to support probe sizes up to 3/16" OD or up to 1/4" OD and all combinations are available to install weldlessly.

How do these differ from other thermowells" For one thing, they're less expensive because we shaved down the threaded fitting end to use less material. All the traditional thermowells have female threads on the insertion end assuming the use of a bimetal thermometer. Our thermowells are designed for thermometers, probes, etc.. that do not have threads on them.

These are all constructed of 304 stainless steel. The well tubing is thin wall for better heat transfer, has a smooth rounded closure at one end and is laser welded to the fitting on the other end. The well tubing also protrudes out of the hex side by about 1/4 inch.

As explained above, the larger well tubing (designated in the model number with an "L") will accept up to a 1/4" OD probe which is very common with temp controllers such as the Johnson Controls A419 series or the similar Ranco ETC-111 series as well as the ST1000 controllers. (we're not endorsing either of them, just using as examples). These units usually include a 1/4" OD probe with a stainless sleeve, but it's not long enough to insert into any vessel on its own. The large sleeve wells are available with either 1/2" NPT or 1/4" NPT threads as shown on the top of the picture to the left.

The smaller well tubing (designated in the model number with an "S") is 1/4" OD and will accept probes up to 3/16" OD. This size is best used for narrow probes found on the popular DTQ450, DTTC, Thermapen, and any other kitchen style digital thermometer. The smaller sleeve units are also available with either 1/2" or 1/4" NPT threads.

Decoding the model numbers, cuz there are so many of them, and it's confusing.... ;-)
