The dmk331 pressure transmitter offers reliable pressure measurement in chlorine dioxide applications up to 20 bar. Features PVDF, ceramic diaphragm, and FKM seals wetted parts for enhanced chemical resistance.
This DMK331 pressure transmitter is specifically configured for applications involving low concentrations of chlorine dioxide (ClO2) where maintaining accuracy and sensor longevity is crucial. This makes it ideal for use in water treatment facilities, disinfection processes, and other industrial environments where ClO2 is employed.
One of the key features of the DMK331 is its resistance to chlorine dioxide at concentrations below 100 mg/L. This is achieved through the careful selection of materials for its wetted parts. The process connection is constructed from PVDF (polyvinylidene fluoride), a thermoplastic known for its excellent chemical resistance, particularly to halogens like chlorine. This ensures that the sensor can withstand the corrosive effects of ClO2, even at elevated pressures up to 20 bar.
Further enhancing its ClO2 compatibility, the DMK331 incorporates a ceramic alumina (Al2O3) diaphragm. Alumina is a highly inert material that exhibits exceptional resistance to a wide range of chemicals, including chlorine dioxide. This diaphragm effectively isolates the sensor’s internal components from the process media, preventing damage and ensuring accurate pressure measurements over time.
The use of FKM (fluorocarbon rubber) O-rings for sealing further contributes to the DMK331‘s suitability for ClO2 applications. FKM is known for its excellent chemical resistance and ability to withstand harsh environments, ensuring leak-free operation and preventing ClO2 from coming into contact with sensitive sensor components.
The DMK331‘s robust construction and material selection make it well-suited for demanding applications where both pressure and chemical resistance are paramount. Its compatibility with chlorine dioxide, coupled with its accuracy and reliability, makes it an excellent choice for monitoring and controlling pressure in water treatment systems, chemical processing plants, and other industrial settings where ClO2 is present.
