About the intelligent pressure transducers
Adding microprocessor power to pressure transducers brings about substantial improvements in their characteristics. Improved measurement sensitivity, extended measurement range, compensation for hysteresis and other non-linearities, and correction for ambient temperature and pressure changes are just some of the facilities offered by intelligent pressure transducers. Accuracies of ±0.1% can be achieved with piezoresistive-bridge silicon devices, for instance. In view of their much superior characteristics, it is perhaps surprising that intelligent pressure instruments represent only about 1% of the total number of pressure measuring devices sold at the present time. The significantly higher cost compared with non-intelligent devices has been cited as the reason for this, but this hardly seems adequate to explain such a very low level of market penetration.
