32500 Electronic Compass & Serial Interface Description：

User's manual

The YOUNG Model 32500 Electronic Compass utilizes a solid state compass module for accurate magnetic heading data and is ideal for mobile and portable applications. The compass module is combined with high resolution interface circuitry to generate useful "true" wind data from the wind sensor. Auxiliary sensor inputs allow connection of other meteorological sensors such as temperature, humidity and barometric pressure sensors. All analog signals are converted to serial format for clear transmission. Supplied in a weather resistant enclosure, the 32500 is mounted on a sleeve that fits on the same vertical mast as the YOUNG wind sensor.

The YOUNG Model 32400 Serial Interface offers the benefits of serial output without the compass circuitry. The serial interface greatly simplifies connection of meteorological sensors to recording electronics with serial inputs. The digital signal is more resistant to electrical interference and errors from line losses and can typically be carried over longer distances using a minimum number of conductors. Model 32400 has a convenient clamp for attachment to a vertical pipe and is also supplied in a weather resistant enclosure.
