GXR Series Gage/Absolute Pressure Transmitter
0-1 through 0-20K psi
General Process Pressure Measurement
Manufactured for reliable service in aggressive environments
The GXR is manufactured for reliability in aggressive environments where other transmitters fail. Dylix’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 316 SS & 17-4 are not best suited, the GXR is available in Hastelloy C276.
Dylix’s Customer Service
Each GXR transmitter is shipped with a NIST traceable calibration certificate.
