Description
SPAN GCS-304 Gas Cylinder Scale 300 lb SAM-304 Scale Amplifier 4-20mA 24VDC
The SPAN GCS-304 is a stainless steel platform scale designed specifically for weighing gas cylinders in laboratory and industrial environments. It is paired with the SPAN SAM-304 Scale Amplifier, which conditions the load cell signal and outputs a standard 4-20 mA analog signal for connection to a process controller, PLC, or display terminal. The scale platform measures 9.25 × 9.25 inches and is rated to a maximum load of 300 lbs.

Applications
Gas cylinder scales like the GCS-304 are used in laboratories and industrial facilities to monitor the remaining contents of compressed gas cylinders by weight — a more reliable method than pressure-based gauging for many gas types. The 4-20 mA output from the SAM-304 amplifier makes this scale compatible with standard process control systems, PLCs, and data acquisition hardware that accept analog current-loop inputs. Typical applications include monitoring of specialty gas supplies in semiconductor fabrication, chemical processing, welding operations, and analytical laboratory environments where accurate cylinder inventory management is important.
This SPAN GCS-304 Gas Cylinder Scale with SAM-304 Scale Amplifier is being sold AS-IS for parts or repair. We do not have a compatible display terminal to test the scale's functionality, so it cannot be verified as working. The unit appears to be in good physical condition — the stainless steel platform shows normal cosmetic wear consistent with prior use, and the blue SAM-304 amplifier module and cable appear intact.
