Brooks Instrument SolidSense II GF Series UHP Pressure Transducer
About this part
GFD01A4SSM is a configured Brooks Instrument SolidSense II GF Series pressure-transducer identifier for high-purity and ultra-high-purity pressure measurement. Official Brooks SolidSense II GF/GI documentation supports the product family and model-code decoding, while an official TE Connectivity product-change notice names the exact part as 2002135-GFD01A4SSM and expands it as GFD-100A-4/20MA-S-FACE SEAL. The supported configuration context is a dead-end, 100 PSIA, 4 to 20 mA, 2 m pigtail with 9-pin D connector, 1/4 inch face-seal swivel-male pressure transducer; final service suitability should be verified from the physical label, calibration paperwork, and process-tool requirements
Configurations vary. Verify the exact unit before choosing a replacement.
