Thermometer and thermocoupler combo unit

**pickles** · 10-01-2009, 08:22 PM

I am sourcing parts for an electric boil kettle and came across this interesting piece. I am wondering if this would be compatible with a PID (probably Auber). In my mind if it will work it would eliminate one fitting on keg and also be a water tight thermocoupler. I read a post lately from Pol about his not being water tight. I know very little about electronics, so bear with me.

Here she is:

Specs:
"50 to 300°F (10 to 150°C) temperature range with an accuracy of ±1% of full scale. It features a 1/2" NPT(M) connection, 3" dial, 6 inch long by 1/4" diameter stem, 304 SS case and stem and glass lens. Built-in 4 to 20 mA transmitter allows data transfer to a PC, control room, or other data acquisition devices."

DO you have a link?

It will absolutely take a 4 to 20 mA input. In the Auber Instrument manual for the SYL-4342 and SYL-4352 it says all you need is an external 50 Ohm shunt resistor. The other Auber PID's are probably the same but check the manuals to be sure. Where can you buy them because I would love to buy one also?

What the heck is that?

Best way to add a thermocouple to an e-kettle in my opinion is to do it via a sightglass. You can get a 4" thermocouple from auberins and a sightglass from bargain fittings. Hook it up to a PID and the PID will give you temp readings while heating and cooling.

What are you talking about? Why in God's name would he neer a sightglass? This thing is perfect for his application. It will screw right into the 1/2" coupler welded right into the side of his keggle or brewpot. The thermometer also has a 4 to 20 mA output which a Auber Instruments PID can use with a 50 Ohm shunt resistor so he doesn't need a second coupler on his brew pot for a thermocouple. The whole idea of using this thing is so he can have a temperature monitoring device which can be connected to a PID and a thermometer connected to his keggle through one coupler.

this seller on ebay has them

Search thermometer in the ebay store. I just bought one and they have one left but a 9" probe on it.

Lots of people want sightglasses, even in keggles. I was just giving the guy another way to get a sightglass and a thermocouple in the same hole and still get a temp read-out.

Thank you, I assume they have more than one of them.
