Make a simple system.
Just plug one of our load cells into our Handheld Display and away you go! The Handheld Display provides power to the load cell and then displays the output in whatever units you've set it up in. Simple and portable - Job done!
Control Switching
If you're looking to act on the values you see, like switch off a pump, set off an alarm or flash a warning light, then we can supply the following:
Our Amp1 'All-in-One' Instrument has optional relays and set points. This allows you to type in two values at which relays will be activated. The relays can be configured to work in multiple ways (momentary, latching, inverted, etc).
Wireless System – Use a wireless transmitter on the load cell (or load cells) and switch equipment with our wireless relay box. The relay box can be easily configured to work with up to 16 load cells. It can switch on individual load cell values, the sum of multiple load cells or the difference between load cells.
Connect Platforms, Silos and Multiple load cell systems
Simple analogue system
The easiest, and cheapest way to measure a load over several load cells, is to connect them altogether in parallel. The resulting signal is then the electrical average of all the units. This method works for most systems where the load is measured in roughly the same position and you’re not looking for very high precision. There are a few points associated with this method which you should be aware of.
Amp3 Universal Amplifier with 3 load cells connected in parallel.
High accuracy analogue system
For higher accuracy systems we would recommend connecting the load cells to an active junction box. This box enables all the load cell outputs to be matched, and eliminates all the electrical interplay between them. This means the output from the active junction is a purely summed signal.
Digital USB system
We can supply our load cells with in-line PC-USB modules, or you can retrofit our PC-USB adaptor to an old load cell. These modules convert the analogue signal into digital data. The digital data can then be read directly into a PC, Laptop or Tablet (running Windows). If you don’t have enough USB ports on your PC you can connect them via a USB hub. The free USB software* can display and log any (or all) of the following in real time:-
Digital Wireless system
We can also supply our load cells with wireless transmitters. By using a PC-USB receiver (Wireless USB PC receiver (500m) ) and the free wireless software you can display and log values as in the wired USB software. The free wireless software ** also allows you to place display boxes on a representation (JPG, GIF, PDF and DXF) of your system, so making visualisation easier. There are also a number of other modules that can “listen in” and use the transmitted data to display, switch or generate an analogue output (0-5V, 0-10V, +-5V, +-10V, 4-20mA).
* Free USB software has a limit of 24 channels. USB hubs need to be powered versions as they supply the load cell with power.
** Free Wireless software has a limit of 100 Channels.
