Load Cell - 50kg, Disc (TAS606)

This single disc load cell (sometimes called a strain gauge) can translate up to 50kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the disc. With this gauge you will be able to tell just how heavy an object is, if an object’s weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.

Disc load cells are a bit easier to mount than bar-style load cells, making them more straightforward to implement into a design.

Each load cell is made from an steel-alloy and is capable of reading a capacity of 50kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows: red = E+, green = O+, black = E-, and white = O-. Additionally, these load cells offer an IP66 protection rating.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • I have a pre-purchase question: Is the 50kg limit distributed across the four cells, or is it a cumulative max. of 50kg? I’d like to build a platform scale to measure liquid volume in a 30-gallon stainless steel kettle. Ideally, I’d like to have +/- 1-quart accuracy. So, a 20lb vessel with 240lb of water in it is about 260lb, or roughly 109kg. In other words, is it reasonable to expect a platform with four 50kg-rated load cells to perform under an expected load of 109kg?

  • 50 kg? I’m assuming that means it can handle the force of a mass of 50kg at the acceleration of gravity, or 490 Newtons of force. Is that right?

  • does it affects the weight result if I attach a magnet on it ?

  • 2000m Wire? I guess that makes this item a bargain. ;)

  • What is the milivolt to force equation for this cell?

  • If I use this cell with the amp board, can I read the data using a voltmeter?

  • This is exactly the type of sensor I’ve been looking for (many months) but for $75 of equipment there is still a 10% error range because it lacks temperature compensation. That’s killing me. You could add a reference sensor (that would have no weight but would measure variations due to temperature, etc) but that would require it’s own whetstone bridge cricuit i beleive(?) so another $75 (?). This still doesn’t appear to fit my needs but i want it to

    • Why not use a full-bridge for your Wheatstone bridge?

      http://www.ni.com/white-paper/3432/en/

      This is designed to mitigate the error that comes up with temperature change.

  • What is the resolution? I do a lot of baking and need at least 1 gram resolution. I’ve been wanting to make my own scale for quite some time.

    • to get 1g accuracy you need 1/50000 of the full scale which is 0.002%. Looking at the datasheet the combined error (accuracy) of this load cell is +/-0.05% So you would struggle to get accurate and repeatable results with such a high range load cell. Try looking for something a bit smaller, a 5kg load cell of the same brand would be a lot more accurate.

      • Thanks for the reply! That was the information I was looking for. Now that I know, it seems obvious, but before I was struggling to understand load cell ratings.

        I ended up ordering the 10 kg wide bar load cell. :/ Seems that may have been a mistake as well…

        • I know you probably want to source all the components from a parts supplier like Sparkfun, but have you considered buying a set of digital scales and salvaging the load cells from them? I have a Brevill Multi Measure digital scale that retails for about $70. It measures 1gram accuracy. Just a thought :)

          • I ended up buying the load cell from another company. What I find odd is that Sparkfun’s load cell selection is for large load load cells. It is almost like they have fallen victim to the “bigger is better” mentality. There isn’t, or at least wasn’t (I haven’t checked again), a single small load cell among the selection. Large load cells have their place, but I suspect that most hobbyists would rather have the smaller cells.
