GCR TRITON PRESSUE AND FLOW LOGGERS TRITON range of data loggers use a new data logging architecture that allows the user to monitor pressure/flow inputs in terms of average minimum/ maximum values based on fast sample rates down to 1 second. TRITON range of loggers store data in non-volatile memory organised into data files. Each data file is an independent data logger with its own start/stop time, sample rate and logging rate. More than one data file can record different types of data for the same input channel. Pressure measurement accuracy is optimised by venting the built in pressure sensors to atmosphere and using multi point calibration. Logged data can be re-calibrated any time by recalibrating the pressure transducer to the logger. Local communications is via a fast non-contact IrDA communications link (115,200 baud). The logger software can also be upgraded in the field via the IrDA communications link. TRITON I D is completely waterproof, submersible and battery powered with a typical battery life of 10 years.
