RFID TAG discussion


Question of RFID source linked

I’m looking for Low temperature tags, to work below -30ºC. I have a customer, meat processing plant, and they need to identify products into a frezzer with RFID. Could someone recommend me anything?

Hi
Do you need inlays, or rugged multi use tags?

For “hard tags” have a look at http://www.confidex.net/
For inlays go to www.upmraflatac.com/europe/eng//RFIDProducts

Best regards

Mariano – the laundry tag has been tested by others to work down to -70…you might want to check it out.

thank you for your reply. I need the label converted with the inlay inserted. Does these tags support -30º (-22ºF)? we need long range read and low price.

You can check out many RFID Tags at www.RFIDTags.com .

I would look at the Intermec Rigid Tag – http://www.rfidtags.com/Intermec

Good luck

Mariano,

We used some in a cold storage application 50K tags ran us approx 22.5 cents.

Let me know if you need any.

Hello,
The temperature will be less of a problem with UHF tags, we’ve tested up to -20C without problems. It’s the texture of your objects, the meat itself, that will detune UHF tags to read ranges of 5 cm. This is unless you’re able to apply the tag so that the inlay hangs in free air more than 5 mm away from the objects. (eg meat not densely stacked and label offset from object controllable).
We’ve run converted HF inlays in production at up to -25c without problems, too. Due to the magnetic coupling you might be able to overcome the detuning / dampening features of the meat with HF. Inlay cost will be higher compared to UHF, but I’d assume you get read distances up to 30-40cm from the tag, it even being buried.

Generally I’d say a tough case unless you’re able to control the environmental circumstances (stacking and label orientation).

I also recommend UPM Raflatac inlays, converted in whatever form, for both approaches.

To add to what others have said, most tags will work in the cold. The major problem will be proximity to any meat-hooks and the meat itself (moisture/ice). See the report from Alien/Boeing/Ohio University/University of Cincinnati ( http://www.rfidsolutionscenter.com/docs/ProjSummary.RFID-Boeing.v1.pdf ) where we were reading tags at -100F/-73C. In it, we were able to use pretty much any tag from a “cold” point of view.

Mariano,
We currently have a rugged tag that goes from 40F-185F. It is Gen II passive tag that can read from 15 feet away. It is used in the waste and meat processing industry. I can send you a tag to test if you would like

Mariano, Kevin Berisso (Ohio University) gave you a good answer. See the report at the RFID Solutions Center or http://www.ohio.edu/industrialtech/aidc/upload/RFID%20in%20the%20Extreme%20Cold%20Chain.pdf , at Ohio University’s Center for AutoID.

Ernesto.

Mariano,

Would be helpful if you describe the application you are working on. Having implemented solutions in meat processing plants before, your client & the FDA have requirements due to the environment and of course, no one wants an inlay showing up after processing. Why don’t you describe what you’d like to tag and how you foresee that item being tagged – and ultimately for how long. Also curious is your requirement for long read range…. why?

Mariano:
I echo Ken’s comments. What are you doing to what and why? Where and when do you need to read the tag during the life of the tag?
There’s plenty of -40 tags around with great read range.

Is RFID/Long Distance read a mandatory requirement…??

I’m aware of Contact based tags which work very well.
