Review of the Fourier Thermometer for HP StreamSmart



#9

Hello,

Here is my first review of the Fourier probes to connect to the HP StreamSmart :

Se you soon for other probe reviews.

Nice review.

Quote:
The probe is, as the Vernier probe for TI, in the form of a long metal rod. ... The cables are thick.

Monsieur! You are talking about measuring, aren't you? So how long is long? How thick is thick?

I take my ruler...

And may I ask if you know the price asked for such probes, like voltage, thermometer, current, etc ?

Do you know if they could be made using only simple components, like PTCs or NTCs for thermometer probe; resistors for voltage and current probes; or do them need some kind of digital control, like ADCs to communicate with the StreamSmart?

Best regards,
Artur

There are some that have digital controls and others that don't. Both digital and analog probes are supported. I think the most common are analog. The probes are sensed by a specific resistance that is unique to each probe.

As to the exact electricals inside however I really don't have much knowledge as I've never tried to figure it out. :-)

Hi, Tim

There are some of these StreamSmart on Ebay for sale, at very attractive prices, but, I couldn't find the probes there. So my questions about them. In the Fourier's site, I couldn't get complete information about probes, but I saw that some ones get the accuracy on bits terms (12 bits most of them), so, I realize that these use digital interface, but, no more information.
Where did you buy your probes?


#15

I didn't... :-)

The streamer reports the information in bits, but I believe the majority of the probes return information to the box as analog data which then converts it.

Olá Artur,

In case you haven't found this information, here it is:

(Thanks Mic for the link studica.com)
