PMD-99T Sapphire Pressure Transmitter
Introduction
PMD-99S pressure transmitters for air compressor can be divided into smart and ordinary in two forms.It adopts the world's most advanced ceramic capacitors sensor technology , thick film electronic technology, measurement without mediation liquid technology, SMT technology and HART communication technology. It has an unique structure, small temperature drift, high stability, strong resistance to overload ability, wide application range, easy installation and maintenance, etc.It can be widely used in metallurgy, petroleum, chemical, machinery, dye, pesticide industry, environment protection, etc. There are mainly three types: PMD-99A capacitive type, PMD-99B diffused silicon type, PMD-99C compact type and PMD-99D sapphire type.
