Brooks Instrument SolidSense II GFD 100 psia 4–20 mA Pressure Transducer
About this part
GFD01A4QSM is a non-display, dead-end SolidSense II GF Series transducer configured for 100 psia full scale, a 4–20 mA output, a 12-inch pigtail terminating in an M12 connector, and a 1/4-inch swivel-male face-seal process connection. The GF Series is designed for stable pressure monitoring in high-purity and ultra-high-purity process-gas systems
Configurations vary. Verify the exact unit before choosing a replacement.

Approval and Installation Notes
Some GFD and GFF configurations are FM approved, but GFD01A4QSM does not establish an approval through its ordering code. Verify the physical product label and applicable certificate before hazardous-area use.
The instrument is factory calibrated and normally requires no field zero adjustment.
Do not use the housing or cable nut as leverage when tightening the process fitting; use a stationary point on the mating gas-line fitting.
