Post by thread:[EE]:Measure liquids temperature with 18S20

Hi everybody. I need to measure temperature on a liquid using a 18s20 sensor from Dallas. Wich is the best way to do it without contaminating the liquid, and obtaining an accurate value of temp.. Thanks in advance. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx -- http://www.piclist.com#nomail Going offline?

What temperature range do you have to cover ?

The water in a hot tub? (same thing?) Any kind of sheath is going to slow down the response, and you have to make sure that any materials that are in contact with the liquid are compatible with it. Industrially, the most common probe material is probably 300-series stainless steel tubing, TIG welded, which meets NSF standards for food contact as well as being resistant to a lot of common chemicals under normal conditions.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 > I would like to know what is the configuration of an IR sensor? Well, that was a message from a while ago... The problem with an IR sensor for this application is that you need to know the temperature of the wine, not the temperature of the surface of the wine. Now, that said, you should be able to put it inside some form of clear plastic tubing that doesn't absord IR, and put that in the wine... As to configureation/calibration, it could be kinda tough to do... I'm not sure what you'd need at this stage. I defer to someone on the list with more experience in this area. - --Brendan -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use <http://www.pgp.com> iQA/AwUBPVwVKQVk8xtQuK+BEQJ5ngCghsM2FaI4tR5qMzG5FAFBUSFiAQ0AoMu8 TG+DNH13s+5aXvXnltNoSwYP =xLap -----END PGP SIGNATURE----- -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
