The portable strain-measuring equipment in use on one of the abutments of Runnymede Bridge is now availabe commercially. It is designed to operate in conjunction with vibrating-wire strain-gauges used to assess longterm variations of strain in concrete structures due to creep, restrained thermal warping, expansion, contraction and shrinkage. The strain-measuring equipment is availabe in two forms, one of which measures strain only, the other being used for the measurement of strain and temperature. The equipment is operated by electric current from batteries contained within the apparatus, a charging circuit enabling the batteries to be recharged insitu from a mains supply. The equipment, which is contained in a box and weighs 32 1/2 lb., is supplied by Deakin Phillips Electronics Ltd.
