Product introduction

Description

Piezoresistive single crystal silicon pressure transmitter

DMP305X single crystal silicon pressure transmitter is a high

performance pressure transmitter with international leading
technology meticulously designed by LEEG instrument, using the
world's most advanced single crystal silicon pressure sensor
technology and patent encapsulation technology.
Single crystal silicon pressure sensor locates on the top of the
metal body and stay away from the medium interface to realizes
mechanical isolation and thermal isolation. Glass sintering sensor
wire realizes high strength electrical insulation of metal base and
improves the capability of flexibility of electronic circuit and
transient voltage resistance protection.
All these original encapsulation technologies enable DMP305X to
easily cope with extreme chemical occasion and mechanical load,
and own strong resistance to EMI, sufficient to respond to the
most rigorous industrial environment applications, which are the
genuine invisible instruments.
