As part of an examination of the problems of instrumentation compatible with on-line computers, a design has been Board Game produced for a simple quasi-digital sensor system.In this, the information about the sensed variable is carried by the number of pulses in a pulse train transmitted by the sensor upon interrogation.This form Jandy TruFit Bubbler Parts of sensor system has a number of attractive features.
The characteristics of the system are analysed and possibilities of further development proposed.
