Series EDN.315 is combined with a diaphragm seal and is used for the protection of pressure instruments in a variety of complex media such as chemical corrosion. Above all, the diaphragm seal separates the pressure gauge from the medium.

 

Pressure is transferred to the instrument via the system infusion fluid inside the diaphragm seal system, with a choice of designs, materials and system infusion fluids for accurate instrumentation implementations in a variety of complex user applications.

 

Threaded models in threaded designs are suitable for versatile applications, and the lower body can be replaced without modification to the diaphragm seal system, which can measure a high pressure range of 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 auxiliaryly, and the pressure measurement can be obtained using a flexible capillary tube.

To select the material of the diaphragm seal in various measurement environments, Daho also offers a variety of solutions in which the upper body of the diaphragm seal and the connected diaphragm parts can be made of the same material or different materials.
