Smart Pressure Transducer Resistive to Aggressive Media
Švéda Miroslav, prof. Ing., CSc., DIFS (FIT)
Sajdl Ondřej, Ing., Ph.D.
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.
