Snow Sensor "Snow Con"
- The control unit has become more compact (23% reduction in installation area compared to the previous model). - Each setting can be confirmed on a digital display, making adjustments easy. - In addition to the conventional operating mode, an 'eco' operating mode has been added. - Manual output is now time-limited and will automatically return to automatic operation after a maximum of 8 hours. - The snow detection method uses a snow-collecting plate system with over 30 years of proven performance. - The sensor unit is excellent in rust prevention and weather resistance, requiring no regular maintenance. - It is compatible with second-stage snow melting power. * Eco operating mode included The eco operating mode reduces the residual snow processing time (standard setting 3 minutes) based on the output time when the output is continuously ON for a certain period. (In the conventional operating mode, residual snow processing activates after precipitation or snow temperature is turned OFF and stops after a certain time.) * For detailed information, please download from the link below or feel free to contact us.

Company information
Niigata Electric Co., Ltd. was founded in 1973 in Nagaoka City, Niigata Prefecture, a snowy region. Since then, we have aimed to effectively utilize water resources and promote energy-saving snow melting systems, developing various automatic control devices and sensors related to snow, including the snowfall sensor "SnowCon." In the field of snow measurement, we have introduced products such as snow depth gauges, snow weight gauges, blizzard meters (SPC), and snow information systems, contributing to the development of snow and ice disaster prevention, snow information, and snow and ice research fields. Some of our developed products are unique to Niigata Electric and are not produced anywhere else in the world. Based on the technology, know-how, and achievements we have cultivated so far, we will continue to actively engage in the development of new products, applied technology, and collaborative research to contribute to a better society and a more livable snowy region. Please look forward to the future of Niigata Electric.
