Product Description

Sapphire pressure transmitter for extreme cold environment

Product Overviews

Sapphire pressure transmitter adopt strain resistance principle, use silicon-sapphire as a semiconductor sensitive element, with unparalleled features. Sapphire series pressure transmitter is made of single crystal insulator elements, will not appear lag, fatigue and creep; sapphire pressure transmitter is stronger than diffuse silicon type, with better hardness and no deformation; sapphire with very good flexibility and insulation characteristics (within 1000 OC), and not sensitive to temperature changes.
