Air Quality
e CR1000 can monitor and control gas analyzers,
particle samplers, and visibility sensors. It can also
automatically control calibration sequences and
compute conditional averages that exclude invalid
data (e.g., data recorded during power failures or cali-
bration intervals).
Road Weather/RWIS
Our fully NTCIP-compliant Environmental Sensor
Stations (ESS) are robust, reliable weather stations used
for road weather/RWIS applications. A typical ESS
includes a tower, CR1000, two road sensors, remote com-
munication hardware, and sensors that measure wind
speed and direction, air temperature, humidity, baro-
metric pressure, solar radiation, and precipitation.
Water Resources/Aquaculture
Our CR1000 is well-suited to remote, unattended
monitoring of hydrologic conditions. Most hydrologic
sensors, including SDI-12 probes, interface directly to
the CR1000. Typical hydrologic measurements:
• Water level is monitored with incremental sha
encoders, double bubblers, ultrasonic ranging
sensors, resistance tapes, strain gage pressure
transducers, or vibrating wire pressure transducers.
Vibrating wire transducers require an AVW200-
series or another vibrating wire interface.
• Ionic conductivity measurements use one of the
switched excitation ports from the CR1000.
• Samplers are controlled by the CR1000 as a function
of time, water quality, or water level.
• Alarm and pump actuation are controlled through
digital I/O ports that operate external relay drivers.
Vehicle Testing
is versatile, rugged datalogger is ideally suited
for testing cold and hot temperature, high altitude,
o -highway, and cross-country performance. e
CR1000 is compatible with our SDM-CAN interface
and GPS16X-HVS receiver.
e CR1000 can measure:
• Suspension—strut pressure, spring force, travel,
mounting point stress, de ection, ride
• Fuel system—line and tank pressure, ow,
temperature, injection timing
• Comfort control—ambient and supply air tem-
perature, solar radiation, fan speed, ac on and o ,
refrigerant pressures, time-to-comfort, blower current
• Brakes—line pressure, pedal pressure and travel,
ABS, line and pad temperature
• Engine—pressure, temperature, crank position,
RPM, time-to-start, oil pump cavitation
• General vehicle—chassis monitoring, road noise,
vehicle position and speed, steering, air bag, hot/
cold soaks, wind tunnels, traction, CANbus, wiper
speed and current, vehicle electrical loads
Other Applications
• Eddy covariance systems
• Wireless sensor/datalogger networks
• Mesonet systems
• Avalanche forecasting, snow science, polar,
high altitude
• Fire weather
• Geotechnical
• Historic preservation
A turbidity sensor was installed in a tributary of the Cedar
River watershed to monitor water quality conditions for
the city of Seattle, Washington.
Vehicle monitoring includes not only passenger cars, but air-
planes, locomotives, helicopters, tractors, buses, heavy trucks,
drilling rigs, race cars, and motorcycles.
