Load Cell Output Signal

Anything that accepts 0-10mA as an input!

How about the same make of controller as the load cell?

If it is a 0-10ma output you could use a Unitronices Jazz Plc Model JZ10-11-R16, but this unit only has 10 bit resolution so depending on the accuracy you require, it may or may not be suitalbe.

But they are value for money at about $350.00 NZ

It is most unusual to have LC with current output. Are you sure it is not a 0-10 mV?

If the LC is supplied with 5V and has a sensitivity of 2E-3 its output will be at full scale 10mV.

I think it is important to check.

nick name,

Yes, there are load cells with current output. We use a lot of them in our factory. It saves us the expense of a weight transmitter.

tarek_10,

The particular load cell we use is of the Sartorius brand. I don't know what brand you're using (Bindicator perhaps? They have a current output load cell as well) but the model we're using requires us to put two current-output load cells (2 to 10mA, in our case) in parallel so that their output sums up to 4 to 20mA. This turns them into the standard current mode signal in instrumentation.

So, for your application, you need to use two load cells in parallel in your application so you'll be able to use a transmitter/indicator with a 0 to 20mA input.

It is a LC with integrated conditioner. And suspicious for me were the 10 mA since the usual current loop is based on the 4/20 mA range.

It is a LC with integrated conditioner...

Exactly.

The Sartorius brand has a provision so that you can select 4 to 20mA or 2 to 10mA. If you're going to use just one load cell, you select the 4 to 20mA mode. If you're going to use two load cells, you select the 2 to 10mA mode and connect the two load cells in parallel so that their combined current output is still 4 to 20mA (2mA + 2mA = 4mA / 10mA + 10mA = 20mA).

I suspect that our friend needs to use two of his load cells in parallel so that his output becomes 0 to 20mA which is one of the standard current outputs.

Gentlemen,

The output can be any component of the EM spectrum; E=I R !

The weight of the load itself will generate a potential and , therefore, connected to ANY load (computer/ analyzer/ receiver, even a VOM) will produce a current. Your sensors convert physical motion into a current of variable values.

Most are called transducers.

The Brand is not important, the function, input and whether or not you can conveniently power the cells is of most import (which may not be necessary).

Simply match the sending units' output to a simple scale computer and calibrate it with KNOWNS.
