lndustrial gauge pressure transmitter

PPT101 Series monosilicon pressure transmitter is a highperformance pressure transmitter with internationalleading technology meticulously designed by Pyrotechinstrument company,using the world's most advancedmonosilicon pressure sensor technology and patentencapsulation technology. Monosilicon pressure sensorlocates on the top of the metal body and stay away fromthe medium interface to realizes mechanical isolation andthermal isolation. Glass sintering sensor wire realizes highstrength electrical insulation of metal base and improvesthe capability of flexibility of electronic circuit and transientvoltage resistance protection. All these original encapsula--tion technologies enable PPTS to easily cope with extremechemical occasion and mechanical load, and own strongresistance to EMl, sufficient to respond to the rigorousindustrial environment applications, which are the genuineinvisible instruments.
