Description
SPAN GCS-304 Gas Cylinder Scale 300 LB Capacity SAM-304 Scale Amplifier 4-20mA
The SPAN GCS-304 is a heavy-duty platform scale designed specifically for weighing compressed gas cylinders. It pairs with the SPAN SAM-304 Scale Amplifier, a compact inline signal conditioner that converts the load cell output to a standard 4-20 mA analog signal for connection to a PLC, controller, or monitoring system. This listing does not include a display terminal — the scale and amplifier are included as shown.

Applications
Gas cylinder scales like the GCS-304 are used in industrial, laboratory, and manufacturing environments to monitor the remaining content of compressed gas cylinders by weight — a more accurate method than pressure gauges, particularly for liquefied gases such as CO₂, nitrous oxide, and refrigerants where pressure does not track consumption linearly. The 4-20 mA output from the SAM-304 amplifier allows the weight reading to feed directly into a PLC, SCADA system, or process controller, enabling automated low-gas alarms or consumption tracking without a local display terminal. These scales are commonly found in semiconductor fabs, welding shops, beverage dispensing, medical gas systems, and industrial process gas applications where continuous cylinder weight monitoring is required.
This SPAN GCS-304 Gas Cylinder Scale with SAM-304 Scale Amplifier has been inspected and is in good used condition. It was pulled from a working environment where it was in use and functional. The stainless steel platform top shows a circular wear mark consistent with regular cylinder placement, and the unit shows general surface wear and light scuffing typical of industrial use. The SAM-304 blue amplifier module and connecting cable are included; no terminal is included. Please view our photo set and contact us if you have any questions.
