■ EDN.616, Explosion-proof Flange Type Diaphragm Seal Pressure Transmitter

- All stainless steel body & wetted parts

- KOSHA Explosion-proof certified

- Flange process connection (DIN / ASME / JIS)

- Pressure measurement up to 250 bar

- CE certified

■ Product Overview

The EDN.616 pressure transmitter can be connected to process systems in a flange type configuration and is manufactured entirely from stainless steel for both the body and wetted parts.

It is certified as explosion-proof by KOSHA in Korea, ensuring safe and reliable operation in hazardous environments.

The diaphragm seal, calibrated and assembled with the pressure transmitter, protects the measuring instrument in complex media such as chemical corrosion and serves as a medium to transmit pressure.

Most importantly, the diaphragm seal isolates the pressure transmitter from the process medium, ensuring sensor protection and stable measurement.

Pressure is transmitted through the internal electronic system and specially filled fluid within the diaphragm seal system, allowing accurate measurement across a wide range of complex applications.

Threaded models are suitable for versatile industrial use, and the lower body can be replaced without modifying the diaphragm seal system, improving maintenance efficiency.

With this diaphragm seal structure, pressure measurement up to 250 bar is achievable.

The diaphragm seal can be directly connected or used with a cooling device in high-temperature environments, and pressure can also be transmitted via a flexible capillary.

To accommodate various measurement environments, DAHO provides options for diaphragm components using identical or different materials, and wetted parts can be coated with Teflon or similar materials if required.
