LEEG Absolute Pressure Transmitter

Absolute Pressure Transmitter

LEEG  Absolute Pressure Transmitter

DMP305X mono silicon pressure transmitter is a high-performance pressure transmitter with international leading technology meticulously designed by LEEG instrument, using the world's most advanced mono silicon pressure sensor technology and patent encapsulation technology.

Monosilicon pressure sensor locates on the top of the metal body and stays 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 the flexibility of electronic circuit and transient voltage resistance protection.

All these original encapsulation technologies enable DMP305X to easily cope with the 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.
