ALIADP_D Series
The D Series diaphragm seal product is designed to work in extreme conditions such as high viscosity, granular, high temperature, and highly corrosive environments. When combined with APT8000, APT9000, or APT9000L transmitters, it forms a robust solution with both direct-mount and capillary-connection configurations. This series supports a maximum temperature of up to 280 °C and offers versatile connection options, including flange and Tri-Clamp styles. It also features multiple diaphragm materials and alternative connection options, making it suitable for food industry applications where vegetable oil can be used as the fill fluid. With its stainless steel construction, PPC coating capillary, and specialized treatment for oil and water, the D Series offers fast response, high accuracy, and excellent stability, even in challenging conditions.
