MODEL 85106
ULTRASONIC ANEMOMETER
2.0 INTRODUCTION
The YOUNG Ultrasonic Anemometer is a 2-axis, no-moving-parts
wind sensor. It is ideal for general meteorological applications
requiring accurate and reliable measurement. The sensor features
wide operating range, compact size, easy installation and low
power operation. Analog and digital signal outputs are available in
several popular formats.
The Ultrasonic Anemometer measures wind based on the transit
time of ultrasonic pulses between four transducers. Air flow alters
the transit time which is used to calculate flow velocity. Wind
direction is determined from relative velocities along each acoustic
path.
Measurement results are available as calibrated voltage
output signals or serial data using RS-232, RS-485, or SDI-12
connections. Continuous output or polled operation may be used.
Serial formats may be selected for direct connection to YOUNG
Wind Tracker displays, marine NMEA systems, SDI-12 data
loggers, and ASCII serial communication programs.
Operating parameter options are selected using a simple setup
program provided. All settings are stored internally in non-volatile
memory.
The sensor is constructed using UV-stabilized thermoplastic,
stainless steel, and anodized aluminum for superior environmental
resistance. It is easily mounted on standard 1 inch (IPS) pipe.
An orientation ring preserves mounting position when the sensor
is removed.
3.0 INITIAL CHECKOUT
Carefully unpack the unit and inspect for physical damage. Any
damage should be reported to the shipper. The sensor arrives fully
calibrated and ready to use. As supplied, the sensor is configured
as follows:
FACTORY DEFAULT CONFIGURATION:
Serial Output:
- NMEA Format
- RS-232
- RS-485 Output Only
- 4800 baud
Analog Voltage Outputs:
- Channel V1: Wind Speed
0-5000 mV = 0-100 m/sec
- Channel V2: Wind Direction
0-5000mV = 0-360 Deg
These settings will permit direct serial connection to the Young
Model 06206 Marine Wind Tracker and connection of the voltage
outputs to a voltage measuring device or datalogger. For other
available serial or voltage output configurations refer to the
appropriate sections of the manual.
A simple operational check of the sensor may be performed as
follows: (Requires Model 06206 Marine Wind Tracker)
3.1 Remove junction box cover and connect power and
signal wires to terminals as indicated in WIRING
CONNECTIONS (APPENDIX A). Supply voltage must
be 9 to 16 VDC.
IMPORTANT: The Wind Tracker input option must be
set to "SER". See the Wind Tracker manual for setting
this option.
3.2 Apply power to the Wind Tracker and sensor. There will
be a 5 second delay for initialization after which the unit
will begin to send data. Wind speed and wind direction
values will appear on the Wind Tracker.
