The sensor is hermetically sealed in a military-rated package. This rugged sensor has a proven performance record that ranges from the desert to the arctic. The wind speed and direction sensors use a solid state, infrared optical design to decrease wear and improve reliability. These rugged sensors, with a design incorporating years of experience and testing, are enclosed in a PVC housing surrounding stainless steel parts. These sensors operate in extreme temperature and wind conditions for years.
Relative humidity is measured with a bulk polymer, resistive sensor.
Thoroughly tested signal conditioning and an industrially-rated housing contribute to the sensor's high accuracy and longevity. The interface device links Capricorn II weather stations to computers and serial peripheral devices including terminals, printers, and modems. All rights reserved, Columbia Weather Systems, Inc.
