XDB317 series pressure transmitters utilize glass micro-melting technology,17-4PH low-carbon steel is sintered on the back of the chamber through high-temperature glass powder to sinter the silicon strain gauge, no”O”ring, no welding seam, no hidden danger of leakage, and the overload capacity of the sensor is 200%FS above, the breaking pressure is 500%FS, thus they are very suitable for high pressure overload.
