Load Cell Testing Machine Upgrade for Laboratory
Load Cell Testing
What was required:
Our client's load cell testing machine had failed and there was no backup, so they came to us for help. Although a vital piece of equipment, it was now old technology and required an overhaul to make it fit for purpose.
Dealing with old technology brings its own challenges, from translating old computer code, transferring data to the new computer and integrating the whole package so it meets or exceeds the client's expectations.
What we did:
We chose to run a standalone PC with its own network card running FactoryTalk ME with a single user licence and with a limit of 15 pages. This is a very well priced product for projects of limited size.
- We installed a bridge controller to an analog converter for the load cell and sent this data to a micrologix controller via ethernet to the PC and third party software for serial data to be collected for data logging.
- With the accuracy of 2mm per minute required to meet the test standards, the old DC drive was maintained with an analog signal input provided by the micrologix.
- This also takes care of all the math calculations for converting load from Kg to newtons and KPA, the rotational speed measurements, and the conversion of string to an integer.
We allowed two weeks to get this system up and running from scratch.
How it helped:
The results were excellent, providing the client with more precise and reliable measurements of weight and compression force. We were able to get this vital piece of testing equipment up and running on time and on budget. This was achieved by spending time with the client to make sure we fully understood the process and its objectives.
