Panel Indicators, Pilot Lights

C461-BR120-NWO is an enabling device used to detect the onset of dangerous conditions and provide signal warnings. Its applications range from industrial process control to household safety equipment, and the working principle of this device is based on several components.

Components

The C461-BR120-NWO enclosure, made from polypropylene, is designed to protect the internal components and environment from dust, water, and dirt. It contains a capsule chamber, or indicator window, that contains the standard incandescence lamp, a metal cylinder that extends upwards out of the window. The lamp is driven by a low voltage current from a power supply unit.

The enclosure also houses a reflector and lens assembly, which is designed to reflect and refractibility and concentrate the light from the lamp onto the indicator window. This provides an intense glow that can be seen from outside the enclosure. The window also contains a calibrated filter, which limits the amount of radiation emitted by the lamp.

Operation

When the external environment indicates the presence of a hazardous condition, a switch is activated which energizes the lamp. The energy produced by the lamp is affected by the reflector and lens assembly, and the light is then focused on the window. The intensity of light passing through the filter is adjusted to indicate the level of danger – the higher the intensity, the more serious the danger. Depending on the type and sensitivity of the indicator, it may also be able to distinguish between different levels of danger.

As well as displaying a warning, the C461-BR120-NWO is also equipped with an alarm. This uses a standard sounder, which produces a loud tone to warn users of potentially dangerous conditions. The sounder is capable of producing a range of tones, from a loud but non-damaging audible signal to a low, continuous background noise.

Maintenance

To ensure that the C461-BR120- NWO remains in good working order, it must be regularly inspected and tested. This should include checking the indicator window for any visible cracks or damage to the glass, the reflector and lens assembly for any signs of wear and tear, and testing the lamp and sounder to ensure they function correctly. It is also important to ensure that the calibration of the filter is correctly set.

Regular maintenance of C461-BR120-NWO ensures that it functions correctly in the event of a hazardous situation. This device is key to protecting people from potential danger, and as such, it is important that proper standards of maintenance are adhered to in order to guarantee its performance.
