Playing Twenty20 role
July 1st 2009 Variohm EuroSensor has
supplied cable-extension
position transducers for the
telescopic floodlighting
systems installed at the Brit
Oval and Lord's cricket
grounds for the 2009 ICC
World Twenty20 Cricket
Championships.
Main contractor, Abacus
Lighting, chose Variohm's
PT9000 series 'stringpot'
sensors from Celesco to
measure and reliably ensure
repeatable position feedback
for each hydraulically
actuated telescopic column
which elevates up to 100
2kW Challenger 3 floodlights
on a 10 x 6m head frame.
By telescoping the masts
from a rested height of 30m
to a typical operational height
of 49m, visual impact and
lighting overspill are
minimised.
The PT9000 series cableextension
transducer is aimed
at long range linear position
measurement up to 45m in a
sealed design that meets IP69
standards. It is simple to
install and the spring loaded
spool, flexible cable and a
rotary sensor mechanism will
tolerate a high level of
misalignment between cable
fixing point and the housing. More articles from Variohm Eurosensor Ltd: |
