Sensors and interfaces

AlpuG is a local reseller of Campbell Scientific UK. AlpuG has more then 25 years of experience with CSI instrumentation and can provide special solutions based on CSI data loggers. AlpuG and its partners have developed many special data acquisition, data transmission and control applications based on CSI loggers.

We provide standard sensors and special solutions:

  • Short and long wave radiation, radiation balance measurements
  • Surface energy balance measurements
  • Air temperature and air humidity with aspirated and unaspirated systems
  • Wind measurements: specially reinforced RMYoung Windmonitors, Infrasonic anemometers, acoustic anemometer WindFlow TM, anemometers with special de-icing systems based on electrical radiation heating, hot air heating and de-icing spray systems
  • Borehole temperature measuring chains, soil- and snow temperature sensors
  • SnoSurf infrared snow surface temperature measuring sensor (pdf19)
