Haris enterprise offers digital differential pressure gauge, model td 3300. This measures differential pressure in spans between 175 and 4800 mm h2o with static pressure up to 100 bar. The pressure measuring element is piezoresistive sensor. It is possible to choose between sensors to satisfy the process conditions. The sensors generate a signal corresponding to the actual pressure and it is complete with a ptc thermistor, which also transmits the temperature of the measuring cell to the electronic system. On the basis of these two values and of the configured parameters the electronic system generates an output signal and displays all the necessary data on the led display. The operating parameters can be changed by means of the four push buttons that are provided below the led display. The features of this microprocessor based pressure switch are wide range for measuring span, square root extraction selectable and automatic temperate compensation in the measuring cell.
