At Advanced Gauging Technologies, safety and clarity are at the core of every instrument we design. While our gamma and isotope gauges come in different models tailored for specific applications, they all share a consistent and intuitive light indicator system. These sensors give operators immediate visual feedback on the gauge’s operational and safety status helping ensure that every measurement is taken safely and accurately.
🔵 Blue Lamp — Gauge Above Upper Limit
If the blue indicator is illuminated, the gauge reading has exceeded the designed upper limit. This may indicate that process material density, level, or thickness (depending on application) is higher than expected. Operators should verify process conditions and ensure that calibration or system limits haven’t been surpassed.
🟡 Yellow/Amber Lamp — Gauge Below Designed Value Limit
The yellow or amber light signals that the gauge is operating below the lower limit of its designed range. This could point to low material levels, reduced flow, or unexpected changes in process conditions. The system may still be functional, but readings might not be within the calibrated accuracy range.
🟢 Green Lamp — Shutter Closed (Safe Condition)
When the green lamp is on, it indicates that the gauge shutter is closed and no radiation is being emitted. This is the safe operating state for maintenance, calibration, or when the gauge is not actively measuring. Operators can safely approach the instrument during this condition.
🔴 Red Lamp — Shutter Open (Radiation Active)
A red light means the shutter is open and radiation is being emitted for measurement. Personnel should maintain appropriate distance and follow all safety procedures while the gauge is active. Only trained and authorized personnel should handle or operate the gauge when this light is on.
Keeping Operators Safe and Informed
Understanding these indicators ensures your team can operate isotope and gamma gauges confidently and safely. Consistent sensor lights across all our models mean that no matter which system you’re using, interpreting gauge status is simple and standardized.
