Analogue datalogger with internal scaling

[DLMUK]

Hi,

I have an application with a load cell where I need to log the load cell output, into a small/internal data logger. But I also want the values to be scaled within the logger.

I.e.

- the output from the load cell to the logger is 0-20mV
- the logger scales this 0-20mV to 0-12tonnes and records the value

The input signal can be either mV/mA or 0-10V.

Does anyone know if such a device exists?

Thanks,

'The input signal can be either mV/mA or 0-10V.' - into what?

How often do you need to log the information?
Where do you plan on storing and retrieving the information?

The most flexible method is to use a small PLC. I would use a Click from Automation Direct.

The analog are scaled in the setup of the unit and be stored in the PLC memory for retrieval.

The retrieval of the data can be done with Modbus TCP using AdvancedHMI. This is a free package.

Here is a free programming series on the Click which also includes communication back to AdvancedHMI.

Hope this helps you out.
