Abstract: Method and apparatus for determining strain data during piling in which a strain gauge transducer mounted to the pile is excited with alternating current signals. The output of the transducer is sensed, amplified and demodulated to produce signals proportional to strain. The demodulated signals are used to control a voltage controlled oscillator whose output is transmitted by a telemetry transmitter via an antenna mounted to the pile. The signals are received at a remote location, converted back to strain proportional signals and recorded. An accelerometer mounted to the pile may be used to remotely turn on the equipment for a predetermined period. The arrangement is particularly suitable for use when piling offshore.
