Threaded Flush Diaphragm Pressure Sensor 316L Sanitary Oil Filled Transmitter Core

A flush diaphragm has a flat sensing surface level with the process connection and no pressure port cavity, so it resists clogging and is easy to clean for viscous, crystallizing, and particle-containing media. The P-type pure flat membrane variant covers -100kPa to 10MPa for applications that require a completely flat sensing surface

The GS23 is designed for pharmaceutical and food equipment, including CIP/SIP hygienic processing environments, thanks to its flush sensing surface and all-316L wetted parts that reduce residue and support thorough cleaning. No hygiene certifications are claimed beyond the confirmed manual specifications; please confirm your specific process requirements with our team.

Working ranges cover 0-10kPa up to 40MPa, with the dimension table including -100kPa to 40MPa. Pressure types are G (gauge), A (absolute), and S (sealed gauge). The G type includes a vent tube that must be kept open to atmosphere so the reference side stays at ambient pressure; keep water and moisture out of the rear reference cavity.

Choose ordering code C for constant current excitation of 1.5mA or code V for constant voltage excitation up to 10V DC. The output is a millivolt signal, full-scale 35 to 230mV depending on range. Common-mode output (output at zero pressure) is 50% of full scale under constant current and 40% under constant voltage.

The GS23 uses a hex ED ring sealing structure with an ED sealing ring of 18.5x23.9x1.5mm in NBR or FKM. The all-316L construction measures liquids and gases compatible with 316L stainless steel and NBR/FKM elastomers. The FKM sealing ring temperature range is -20 to 200 deg C. FKM has limited low-temperature performance, so exercise caution below -20 deg C.
