The scope
What is measured
- Sector
- Electronics
- Instrumented machine
- Air compressor, oven and component placement machine
- Measured quantities
- Vibration of the compressor and the component placement machine
- Compressor and oven current, via current clamps
- Energy (kWh) and power
- Detected events
- Compressor running while production is stopped
- Compressed air leaks
- Costly standby outside working hours
- Overconsumption for the same output
- Poorly lubricated motors
- Achieved result
Compressed air leaks detected and quantified, and a compressor read against production activity. What the measurement asked of the site IT network: 0 access requested. The unit reports over LTE-M, on its own SIM card.
The deployment
Control points
Equipment : Air compressor
What is measured : A Sybox on the compressor, and current clamps on its supply.
What it showed : Compressed air leaks are detected and quantified.
Equipment : Component placement machine
What is measured : A Sybox on the machine that places components on the boards.
What it showed : Its activity is the reference: the compressor is read against production.
Equipment : Oven
What is measured : Current clamps on the three phases.
What it showed : Its consumption and its standby outside working hours show up.
Compressed air and electricity are now read against production: a compressor running for nothing shows.
Reading still to come
This deployment has no published figures yet: leak volume, energy used idling or on standby, the consumption gap for the same output. The commissioning date and the observation period are missing too.
Those values exist on the customer’s side and must be approved by them before publication. This site publishes no gain figure without a source; the panel will stay as it is until then.
In operation
What it changed
- A compressor running for nothing showsWhen the placement machine stops and the compressor carries on, the gap is plain to see.
- Compressed air leaks have a sizeOnce measured, they are dealt with in order of importance.
- A poorly lubricated motor gives itself away
Electricity and compressed air consumption could at best be read for the site as a whole: there was no telling whether the compressor ran for production or for nothing.
The installation needed no wiring into the machines and no access to the site IT network: the Sybox sends its readings over the cellular network.
