This product EDN.617 has a two-stage process flange structure in the process, the inside of the top flange is coupled to the diaphragm, and the bottom flange consists of a flange according to the standard for connection to the process. Both the body of the pressure transistor and the wet parts of the process flange are made of stainless steel, and the explosion frame-proof product has been obtained by KOSHA in Korea.

 

The diaphragm seal, which is calibrated with the pressure transistor, protects the pressure instrument in a variety of complex media, such as chemical corrosion, and is used as a medium to deliver pressure measurements. Above all, the diaphragm seal maintains the role and function of separating the pressure transistor from the media.

 

Pressure is transmitted to the instrument via the electronic system and the injected special fluid inside the diaphragm seal system, and a range of designs, materials, and system injection fluids are selectively available for accurate measurement implementations in a variety of complex user applications. In the threaded design, the models with threaded connections are suitable for versatile applications, the lower body can be replaced without modification of the diaphragm seal system, and the drive of these diaphragm seals can measure the high pressure range up to 250 bars.

 

Mounting the diaphragm seal to the measuring instrument can be directly connected, or at high temperatures, the cooling system can be used as a supplement, and the pressure measurement can be obtained using a flexible capillary tube.

 

For the material selection of the diaphragm seal in a variety of measurement environments, Daho also provides a variety of solutions where the diaphragm parts connected to the upper body of the diaphragm seal may be used in the same material or may be made of different materials. Parts that come into contact with the medium may alternatively be coated with Teflon or a similar material.
