Introduction

The SPR-325MVWT31 is a discrete LED indicator that is designed for lightning warning, wind measurement and general warning applications. This piece of equipment is an economical, rugged and reliable tool for indicating wind speed, wind direction, and thunderstorm activity in both indoor and outdoor settings. The SPR-325MVWT31 has the ability to detect and react to changes in air temperature, humidity, wind speed and direction.

Design and Features

The SPR-325MVWT31 is a self-contained assembly that contains a housing and mounting frame with a red/green bi-color LED display. The housing is constructed of ruggedized aluminum which provides for high durability and long life in harsh environmental conditions. The display is sealed in a double-sided aluminum anodized enclosure to provide protection from elements such as ultraviolet radiation, salt mist, and corrosion. The two-color LED display consists of six LEDs, three colored in red and three colored in green. Each LED can be independently illuminated and de-illuminated in order to indicate changes in wind speed, wind direction, and thunderstorm activity. The LEDs can also be grouped and illuminated in order to indicate severe weather conditions or hazardous circumstances. The SPR-325MVWT31 is powered by a 12 or 24 volt DC power source and features a variety of mounting options. The enclosure is designed to be mounted flush with walls or posts, and the LED display can be easily visible in daylight. Additional features include adjustable LED brightness, temperature and humidity sensors, and adjustable wind speed and direction thresholds.

Applications

The SPR-325MVWT31 is specifically designed for lightning warning, wind measurement and general warning applications for indoor and outdoor use. It can also be used for a variety of other applications, such as environmental monitoring, security alerts, and public safety warnings. Additionally, the SPR-325MVWT31 is suitable for use in industrial, commercial, and residential buildings.

Working Principle

The SPR-325MVWT31 operates on a simple and reliable design principle. The device is connected to a power source and the two-color LED display is illuminated in response to changes in wind speed, wind direction, and thunderstorm activity. The sensors measure changes in air temperature, humidity, wind speed and direction, and react according to pre-set thresholds. When the threshold is exceeded, the LEDs are illuminated in order to indicate the existence of hazardous conditions. The SPR-325MVWT31 is designed to meet a wide range of environmental conditions. The enclosure is constructed of ruggedized aluminum and is sealed to provide protection from elements such as ultraviolet radiation, salt mist, and corrosion. The unit is powered by a 12 or 24 volt DC power source and includes adjustable LED brightness, temperature and humidity sensors, and adjustable wind speed and direction thresholds.

Conclusion

The SPR-325MVWT31 is an economical, rugged, and reliable LED indicator designed for lightning warning, wind measurement and general warning applications in indoor and outdoor use. The unit features a two-color LED display that can be illuminated in order to indicate changes in wind speed, wind direction, and thunderstorm activity. The device is powered by a 12 or 24 volt DC power source and includes adjustable LED brightness, temperature and humidity sensors, and adjustable wind speed and direction thresholds. The rugged aluminum enclosure ensures protection from elements such as ultraviolet radiation, salt mist, and corrosion.
