■ Product Overview
CDS.933
is a diaphragm seal accessory designed to protect pressure measuring
instruments in applications involving aggressive, highly viscous,
crystallising, or high-temperature media.
The
diaphragm seal system isolates the measuring instrument from the process
medium, preventing damage and ensuring long-term stable measurement
performance.
■ Pressure Measurement Principle
Process
pressure is applied to the diaphragm and transmitted to the measuring
instrument through the system fill fluid.
The
diaphragm isolates the instrument from the process medium while ensuring
accurate and reliable pressure transmission.
■ Materials (Materials of wetted parts)
CDS.933
uses stainless steel 316L as the standard material for wetted parts, providing
excellent corrosion resistance and durability.
Optional
materials such as PTFE, Titanium, Tantalum, and gold plating are available to meet
specific process requirements, including corrosive or high-temperature
environments.
Key
wetted components are manufactured using high-quality materials sourced from
Korea and Germany.
■ Applications
CDS.933
is designed for use in demanding industrial environments requiring reliable
protection of pressure instruments.
It is
suitable for applications involving aggressive, viscous, high-temperature, or
crystallising media.
