SMP858-DST Piezoresistive single crystal silicon differential pressure transmitter SENSING TOMORROW Product introduction Piezoresistive single crystal silicon pressure transmitter SMP858 piezoresistive 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. Main parameters Pressure types Differential pressure Measuring range 4kPa-1MPa, please refer to the ordering information chapter Output signal Reference accuracy ±0.2% URL, optional ±0.5% URL Pressure, level, differential pressure, density, interface, flow Measuring medium The fluid which compatible with wetted parts Disclaimer: all the data used in the product description is not legally binding. Relevant technical details may be changed due to further improve 2016.05.V1.0
