Original Abstract
The pressure transducer was researched to reach the IEEE 1451 functionality, better pressure ranges and lower price. It is typically prepared for paper and chemical industry, medicine appliances and pharmacy: designed to 0 ... 10 kPa up to 0 ... 6 MPa pressure ranges, accuracy according to IEC 60770 0.5% FSO. The ceramic diaphragm for pressure sensing is applied and a new principle of special ASIC with multiplexed frequency transmitter for conditioning of fX and fR frequencies controlled by CX and CR sensor capacitances is exploit. An efficient protection against the moist and dusty ambient air and surrounding electromagnetic parasitic fields is achieved.
