D.4 Pressure transducers are 4 types of pressure transducers; Gauge, absolute, differential, and vacuum. These sensors greatly vary in size, pressure capacity, tolerance, and can have chemical and/or dust treatment as well. Table D4. Advantages and disadvantages of pressure transducers Pressure sensors Advantages Disadvantages Easy to read Atmospheric pressure has to be accounted for. Two sensors are needed for differential pressure. Direct measurement of pressure Gage pressure requires some Atmospheric pressure is included work to calculate. Absolute Two sensors are needed for differential pressure. Atmospheric pressure is not needed. Unidirectional measurement only Differential Direct measurement between two Compounding failure point chambers. Sub atmospheric pressure Only measures negative pressure. Vacuum measurement. Pressure chambers can switch Compounding failure point between high and low pressure. Bidirectional Atmospheric pressure is not needed. Direct measurement between two chambers.
