A high-resolution visible light sensor with isolated industrial voltage outputs for plasma and general light-source detection and intensity analysis.
Plasma Detector is a high-resolution visible light sensor for detecting and analysing the intensity of plasma and general light sources.
Its fully isolated industrial voltage output supports common sensor standards (0–5 V, 0–2.5 V, 1–5 V, 0.5–2.5 V), so it plugs straight into any industrial measurement system. A built-in display shows readings and output voltage in real time, and every parameter can be set independently to suit different environments.

Key features
- Four measurement modes: visible, infrared, visible + infrared, and high-sensitivity visible.
- Sensitivity down to 0.01 lux with a range of about 3,500 lux; in high-sensitivity mode, down to 0.001 lux with a range of about 8.1 lux.
- Output voltage freely adjustable between 0 and 5 V to match any industrial sensor standard and connect directly to voltage data-acquisition systems.
- Output Mapping lets any detection window be scaled to the full output range.
- Machines with very different plasma intensities can be tuned to nearly identical output voltages.
- Fully isolated V+ and V- outputs keep the connection to downstream acquisition systems safe and accurate.
