Description

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.

Features:
* Originally patented fully-sealed, fully-isolated single crystal silicon pressure sensor.
* Double diaphragm overload protection structure can easily cope with high overload test.
* ASIC and SMT signal transmitting module. Friendly button parameters operation function, display measured data quickly.
* Multiple temperature and linearity compensation to improve accuracy
* Superb stainless steel welding technology and surface treatment process conform to international sanitary standard.
* High strength metal electrical protection housing to assure long performance life.
* Solid and superior stainless steel process flange. Strong safeguard with high static pressure and high overload.
