NPT to Thermometer Probe PDF Print E-mail

Model: ProbeComp - $15+tnthroughwall2tnthroughwall3

If you want to insert a narrow digital thermometer probe into a a hole in your vessel, a threaded fitting such as a tee or a coupling welded into your vessel, here's how to do it. This fitting has 1/2" OR 1/4 male NPT on one end and will accept up to a .25" diameter probe (see notes). The included orings make a leak free connection. You can also get this as a weldless setup. See more info for application pictures, etc.

 


Options:

  1. 1/2" Male NPT to Narrow Probe: If you want to insert the CDN Proaccurate thermometer or a right-angle probe that comes with remote kitchen thermometers. The range of probe diameters supported with this fitting is 1/8" to 1/4". This can be used for both the handheld/remote probes as well as 1/4" capsules like the A419 controller sensors. 
  2. 1/4" Male NPT to Narrow Probe: This version is specifically offered to thread into the open end of the tee in the WLSTNT kit to add digital or remote temperature functionality instead of threading a dial thermometer in. Again, this one is 1/4" NPT male threaded. There is no picture of this option on the page. You can also make this weldless by also adding the 1/4" make weldless kit below. This one only supports probe diameters of up to 3/16" but can be modified for A419 (1/4" OD) probes by drilling the fitting out with a 1/4" drill bit.
  3. 1/4" Male NPT to Narrow Probe with extended weldless bulkhead for cooler walls up to 1.25" thick.Install notes on this one: Drill a 9/16" hole all the way through both walls of the cooler. Open up the hole in the outside skin of the cooler to about 3/4 and chip out the foam insulation a bit to reveal a clean interior wall surface. The bushing and metal washer insert from the inside. The red gasket gets pushed over the bushing from the OUTSIDE of the inner wall. It's tricky to get it on, but that's how it's designed. Now insert the compression fitting/coupling down into the hole and thread the bushing into it by turning it from inside the cooler. A little tighter than hand tight is enough to create the seal against the gasket.
  4. 1/4" Female NPT to Narrow Probe with Weldless Parts- Buy this option if you just want to drill a 9/16" hole in your thin-wall vessel and install a narrow probe thermometer. This is the most economical way to do it. 

Note, if you're installing the CDN DTQ450 using option 4 into a direct heated vessel, we highly recommend clipping our HS.SM heatshield onto the fitting to protect the thermometer from intense heat.

Instructions for installing a thermometer into any of these fittings: Once you have the fitting installed into your flow or into your vessel, remove the compression nut from the fitting and place it over your thermometer probe with the open threaded end towards the point. Push the two included red orings over the probe and then insert the probe into the compression fitting. Thread the compression nut onto the fitting to sandwich the orings. Hand tight is generally enough to create a seal. Do not overtighten with a wrench more than one additional turn past hand tight.

Some additional usage ideas for the 1/2" NPT version:

 

inlinetemp3The first, and our favorite use is for monitoring the temperature of the wort coming out of a plate or counterflow chiller as shown on the left. The basic compression fitting in threaded into the end of a 1/2" NPT TEE which is in-turn threaded onto the plate chiller output. The side port of the tee is where the wort will actually flow out. In this example application we show a Camlock Type F but it could also be  a hose barb.


inlinetempExpanding on this basic concept, you can also insert a camlock disconnect "pair" between the tee and plate chiller to make the inline temperature assembly more portable and therefore usable in other stages of brewing. For example, you may use it to monitor the output temp of your mash in a recirculation system. In this case, we're showing a camlock type B on the left side of the tee which would connect to either a type A on a plate chiller or a type F on the output side of any vessel ball valve. NOTE: None of the extra parts shown in these typical application pictures are included if you add this item to the cart. However, the camlocks, tees, barbs, etc are all available separate items on the Fittings Pages.
