space Product Description:
 

Designed for hazardous locations Senex’s GXR Series Pressure Transmitter is designed for use in hazardous locations. The GXR’s entirely welded 316LSST construction is hermetically sealed, and Factory Mutual and Canadian Standards Association Explosion Proof certification are pending.

Manufactured for reliable service in aggressive environments The GXR is manufactured for reliability in aggressive environments where other transmitters fail. Senex’s automated weld procedures, extreme environmental burn in, and the mounting of our electronics to withstand the most severe shock and vibration applications are all geared toward safety and reliability. Additional EMI/RFI filtering with surge protection add to the performance of the GXR.

Alternate materials for service in corrosive environments For corrosive environments where 316L or 15-5 SST are not best suited, the GXR is available in Hasteloy C276, C22 or Inconel 718.
