Automatic Regulation unit
In an age where large public clocks have the ability to be auto-wound, the need for a dedicated person to wind the clock has now gone. However, this same person was required to correct any gain or loss of the clock on a regular basis, which detracts from the ability of a clock to run untouched for long periods of time. This same person was also responsible for carrying out daylight saving time changes (e.g. GMT to BST changes).
 

The Auto-regulator system is a discrete unit that is mounted on the rear of the clock that regulates the beat of the pendulum to a reference to the Atomic Clock via the Rugby radio signal (MSF), or GPS

The Unit also allows the user to programme the day light saving time changes which will stop and start the clock at specific times to reflect local time.

  • Timing to within 10 seconds per year (in some cases to within 0.2 of a second per year)
  • Making time adjustments to meet winter/summertime changes
  • The arc of the pendulum is not to be effected beyond that of it's normal operation.
  • Self synchronising
  • Ability to be fitted unobtrusively and discretely
  • Battery-backed to continue operation during power failures
  • Atomic clock radio linked via MSF or GPS
  • Disciplined Crystal based internal time keeping in the event of GPS/MSF signal Loss
  • Ease of maintenance - typically 12 months for routine inspection, and battery replacement every 5 years.
  • Control unit size - 200m/m x 200m/m x 200m/m, steel cased, approximately 2.5Kg, wall or floor mounting
  • Adjustment unit size - 40m/m x 30m/m x 100m/m, (typical - but will vary dependent on clock size)

The Auto-regulation system has been derived through a general demand for accuracy for public clocks that is, automatic in operation, and preserves the existing installation with no material changes to the clock.
