After many testing, Broadsens updated its wireless vibration and temperature sensors' rating from IP67 to IP68. This rating could truly reflect the ability of the sensors working under tough environments. The testing were performed in different environments, including ice water submerge, deep water submerge, and long duration water submerge. The testing proved that Broadsens wireless vibration and temperature sensors are some of the best and toughest in the industry.
Ice water submerge testing
In this testing, Broadsens's wireless vibration and temperature sensors are submerged under iced water for more than 1 hour. There were random-selected one SVT-A series and one SVT-V series wireless vibration sensor. Both sensors took data continuously. Yes Broadsens's innovative design allow the ultra-low power wireless vibration sensors take data continuously.
SVT-A wireless vibration sensors include SVT200-A, SVT300-A and SVT400-A. They take triaxial acceleration raw data, which allows for predictive maintenance and AI-based analysis.
Both type of sensors should be used for industrial IOT applications.
In the pictures below, the left pictures show long-duration testing. In this test, the sensors were submerge in a water bottle for more than 48 hours. There is no leak detected and the sensors are working normally after 48 hours. In the right picture, the sensors were submerged under a well water with a depth of 1.5m for more than 4 hours. The sensors are also working normally without any water damage. The wireless vibration and temperature sensors are perfect solutions for industrial IOT applications and machine condition monitoring.
