Excellent Value - Great for Industrial Controls Testing

High quality product, used on an R&D project to design a process oven. Stacked 6 of these boards together to read 24 thermocouples. Easy setup, great value at the price point. Other systems to read the sensors were 2-3x times the cost.

Great HAT for my application

I've been searching for an open source thermocouple measurement system to replace a LabVIEW based system. This Raspberry pi HAT met my requirements perfectly. The software install was straightforward and I was up and running within an hour of fedex dropping off the HAT. Everything was provided in the package to install and secure the HAT to my Pi. One recommendation I would make is to design a case for the Pi with one HAT. This would have helped. Fortunately I was able to dig a case out that worked.

This Pi Hat is awesome.

I've actually installed the hat and tested it out. I actually really like that it supports different types of thermocouples. I've found the provided software and examples really easy to use. Would honestly recommend it.

Works and easy to use

We needed a way to monitor the temperature of our wash tanks and this did exactly what we needed, actually it was the rinse side but it worked for that also. We can now log temperature so we can see if there is a relationship between a problem we have been having and water temperature.

It simply did the job.

I bought this for a hobby project, since I had no idea how to calibrate a thermocouple or any kind of thermal probe. This simply solved the problem, and I could move on to the problems I was really trying to solve.

Is there an inherent temperature range for these boards, or does this support the full range of temperatures supported by the chosen probe? For example, can this board accurately monitor temperatures from -80C to -196C? (Typical low temperature applications in research settings).

Answers

Yes, there are several supported thermocouples that can go down to -270 C. The temperature ranges for the supported thermocouples is listed in the User’s Guide here: https://mccdaq.github.io/daqhats/_static/esmcc134.pdf

With the hat installed, can you still connect to the GPIO (assuming it’s a pass thru) to access the RPI’s serial port(s)?

Answers

All of the bus pins on the HATs are physically passed thru to the next HAT module in the stack. However, pins that this, and any other HATs use, may not be available for your use. Here is a FAQ showing which pins each of our HAT devices use: https://kb.mccdaq.com/KnowledgebaseArticle50812.aspx

Hi, Just wondering if MCC has a 3D enclosure for this and if they offer the STL? Digilent did something similar with their OpenScope data logger. It was a nice extra and didn't cost Digilent any money to manufacture since this was offered to anyone who wanted to print their own. Just a thought.

Sorry, MCC does not offer a 3D enclosure for our HAT series. We do however, have 3D STP files for each of our HATs that can be emailed to you upon request. Please email us at [email protected] to request the STP file for the MCC 134.

Do you provide calibration certificates for the raspberry Pi based product?

Dave Rockville, MD


Answers

Cal certs are not included, but can be provided upon request The certs do not contain data. All HATs are calibrated with NIST traceable equipment. For the thermocouple HAT (MCC 134) it’s CJC sensor accuracy itself is not tested; It’s voltage measurement accuracy is.

Considering the changes between the Raspberry Pi 3 and 4, is this HAT compatible with either of the series, or specific to only one.

I would like to include the data from multiple Mcc134s in a single plot. Is there a simple way of going about this?

  • Job Title: Mechanical Engineer

Michael Honolulu, Hawaii


Answers

The single-HAT graphing example, /134/data_logger, first calls the function hat_list() to enumerate the MCC 134, then goes into a timed loop and calls mcc134_t_in_read(), getting one reading per channel. You could call the same functions up front and in the same timed loop … just change the board # (or how to refer to the second board). The graphing portion of that example uses 3rd party utilities that we show for convenience, but we do not support the expanded use or features of the 3rd party graph API. You can contact our tech support, specifying which language (Python or C), to ask more specific questions on MCC own API, which is specific to our HATs.

Do you plan to add drivers for functionality with Node-RED? It would be great if there was a "node" available to access all of the MCC boards.
