Site Visit

the benefits of an onsite visit

Depending on the application an onsite visit is optional by our Technical and Project Management Team. Some are simple whilst others more complex.

For example; Advanced Manufacturing

In discussion with a high volume component manufacturer on what to measure on their paint line it was agreed on the site visit that ‘we’ were unnecessarily restricting the outcome of the attributes being looked at; Humidity, Air flow, Temperature and Pressure.

Upon the review we felt that there were important further insights to be gained by additionally monitoring how those desired levels are achieved.

Taking Air Flow as one example:

  • The output is the air velocity measured by an anemometer
  • The air only moves because it is blown by a fan
  • We assume that there is more than one fan per paint line
  • If so, unexplained variations in the air flow could be better understood by knowing the air flow generated by each fan
  • The fact the fan motor is running can be a simple digital input, and its airflow measured with more anemometers
  • The current draw of the fan could be monitored, this would indicate bearing or winding failures
  • The vibration of the fan assembly could be indicative of imbalanced (dirty) fans or bearing failure (accelerometer)

Looking at the interrelationship between all these factors this gave the maintenance team much more to work with when trying to determine what is happening on the output end “the air is not moving enough”, “the air flow varies too much”.  If all the fans are blowing a constant velocity then if the air flow varies we know it is not the fans and something else (something in the paint line causing eddies) or the measurement is taken in the wrong place.

Other example potential items that we suggested to measure:

  • Are all the water pumps running
  • Pump current draw (bearings, windings)
  • Pump vibration (bearings)
  • Water level too high/too low (float switches) digital – drain blockages
  • Water temperature (affects humidity in the room)
  • Heater elements (on/off)
  • Heat exchanges gradients with air into water (warm the water with the warm air from the line, so the room has heated back from the water.
  • Paint arm running time
  • Paint arm current
  • Paint arm vibration

In the above example, it was agreed that there was a need in measuring and monitoring a wider range of needs that would benefit the control and costs. This was only achieved by being onsite.

We are keen that all our clients maximise the benefit from utilising our technology and due to the innovative nature of our solution it helps to assess and engage with those onsite.
