WATERTOWN, Mass. And ZIJTAART, the Netherlands - Exergen Global today announced that its IRt/c.10, infrared unpowered sensors with a field of view of 10:1, are being used to measure the temperature of snowy, icy, grungy surfaces by over 20 complex meteorological stations in Kazakhstan.
The meteorological stations measure many variables for data acquisition for weather forecasting and meteorological research. The Kazakhstan government employs these stations in mountainous areas where there’s seasonal risk of flooding. By accurately measuring snow surface temperature, in combination with other parameters such as snow height, ambient temperature and humidity, a reliable prediction can be made how much melting water is generated, allowing flood forecasting for safety measures.
“The problem we had to solve was pretty complex as we are dealing with variable ‘cold’ temperatures, various layers of snow and changing temperatures during the day because of the sun. This is the real world in Kazakhstan, a vast country of Central Asia with very cold winters from cold air masses of polar or Siberian origin”, said Abdul Razakov, Project Manager of MICROSTEP-MIS.
The temperature in the Northern part of Kazakhstan can drop to -50°C in wintertime, where the northern wind can cause snowstorms, whilst there are over 100 days with snowfall each year in the Northern part and 60 days in the central region. Those harsh conditions demand solutions enabling to measure the temperature of the surface very accurately. This data needs to provide reliable information when snow or ice will melt, causing possible flooding. The measuring was done manually and for safety and cost- efficiency reasons, this needed to be automated. Initially a contact temperature probe was employed on the station, but this method was very unreliable especially with varying snow heights.
“For this environmental safety monitoring, Exergen’s IRt/c.10 provides a very solid solution. As it offers a very narrow field of view at a rather large distance, it is still able to measure small spots very accurately. If there is a lot of snow, no snow, or only ice, this sensor provides very precise measurements automatically, which is exactly what complex meteorology stations need”, said Bram Stelt, CEO Exergen Global.
“The additional plus, what we consider as very unique, is that the IRt/c.10 is unpowered. Complex meteorology stations in Kazakhstan always face problems with batteries. The system works approx. 5 hours a day and the fact that the IRt/c.10 is not requesting any power, is an additional nice benefit”, added Abdul Razakov of MICROSTEP-MIS.
