Adding a Stagehand Pro 4 or 5 and a machine with a compatible load cell to Spikemark 5 allows you to see live load cell data in Spikemark and on the Stagehand Motion Controller. You can also set overweight and underweight thresholds to automatically stop motion.
To use this killer feature you will need the following:
Load cells are currently available on the following Creative Conners machines:
No matter the machine, load cells are only serviceable by a qualified technician.
Unfortunately, Broadweigh load shackles are not compatible with Spikemark and the Stagehand.
Load cells come in many shapes and sizes. When specifying a load cell you need to keep several factors in mind:
- Data signal - Is the load cell sending a digital or analog signal back to the reader?
- Peak loading potential - An e-stop puts large loads on the entire system, and a load cell needs to be in line in order to read the weight. Make sure it’s beefy enough to withstand the shockload of sudden stop.
- Installation criteria - Where are you actually measuring the force? A shackle is easy to identify, but a torque arm buried inside a machine can also work.
There are a few ways to read the load data, but the most accessible is the 4mA to 20mA analog signal - which is the type that is compatible with the Stagehand Pro 4 and Spikemark.
