Monitoring Analogue and Digital Signals

At Caption Data we focus on certain application areas and Market sectors, however all of these are doing essentially the same things.

That is, taking signals or input/outputs from sensors, instruments, transducers or control systems, then capturing the data and transmitting that data securely via the mobile phone networks to our secure servers; then allowing client access to a cloud service where the data is already shown graphically illustrating trends and relationships, and with a host of other functionality.

This functionality includes things like:

  • Setting hi/lo alarms on all parameters
  • Setting monitor and report frequencies [from 1 min to 1 day]
  • Setting alarm recipients, by email or SMS
  • Dynamic charting with ability to annotate and share
  • Management reporting
  • Audit trail
  • API
  • … and much more

So although we tend to focus on specific areas, the reality is that many of our products will work seamlessly with any number of other measurements.

The circuitry does not care what it is measuring!

So when a new customer asks us to monitor a parameter we have not worked with before it is often straightforward and quick to implement!

Analogue Signals

Analogue signal

Analogue Signal

Analogue signals vary continuously over time [for example sound, where microphones turn variations in air pressure into analogue signals] , and instruments tend to have common output ranges eg nowadays  4-20 mA or historically 0-10 Volts.

In theory an analogue signal has infinite resolution, although there are a host of practical reasons making this not so. Consequently many traditionally analogue devices have become digital over the years.

Case Study One - Remote monitoring points the way to corrosion prevention

Corrosion of pipework and components in water based heating and cooling systems nearly always results in costly repairs and unwelcome disruption, especially where a large office block, hospital or district heating scheme is concerned. When failures occur in the low temperature hot water (LTHW) or chilled water (CHW) systems the tendency is to investigate the failed component and possibly much later to call in specialist corrosion consultants to find the root cause of the problems and recommend a solution.

In this case parameters being measured include dissolved oxygen, pH, flow and pressure.
