Vehicle Monitoring and Testing
The versatile, rugged design and low power requirements of the
CR9000X-series dataloggers make them well suited for vehicle
monitoring. They excel in cold and hot temperature, high altitude,
o-highway, and cross-country performance testing. The CR9000X
series is compatible with our SDM-CAN interface.
Compatible sensors often used for vehicle monitoring and testing in-
clude thermocouples, pressure transducers, GPS receivers, pulse pick-ups,
ow transducers, potentiometers, strain gages, load cells, digital switches,
accelerometers, LVDTs, and tilt sensors. Most sensors connect directly to
the datalogger, eliminating costly external signal conditioning.
Common measurements include:
Suspension—strut pressure, spring force, travel, mounting
point stress, deection, ride.
Fuel system—line and tank pressure, ow, temperature,
injection timing
Comfort control—ambient and supply air temperature, solar
radiation, fan speed, blower currents, ac on/o , refrigerant
pressures, time-to-comfort
Brakes—line pressure, pedal pressure and travel, ABS, uid and
pad temperature
Engine—pressure, temperature, crank position, RPM, time-to-
start, oil pump cavitation
General vehicle—chassis monitoring, road noise, NVH, traction,
payload, vehicle position/ speed, steering, air bag, hot/cold soaks,
wind tunnels, CANbus, wiper speed/current, vehicle electrical loads
Vehicle monitoring includes not only passenger cars but locomo-
tives, airplanes, helicopters, tractors, buses, heavy trucks, drilling rigs,
race cars, ATVs, and motorcycles.
Other Applications
Aerospace/aviation—can endure the rigors of space travel
and provided acceleration, structural, and equipment perfor-
mance measurements.
Geotechnical—measures tilt, convergence, displacement,
geographic position, strain, load, vibration, overburden, level,
ow, creep, and force for slope stability, subsidence, seismicity
studies, structural restoration, or site assessment applications.
Mining—monitors mine ventilation, slope stability, convergence,
and equipment performance
Machinery testing—provides temperature, pressure, RPM, velocity,
power, acceleration, position, torque, and strain measurements.
Laboratory—can serve as a monitoring device to record parameters
over time and can also be used to regulate and control test conditions.

Compatibility with Retired Products
Customers can add CR9000X-series dataloggers to networks
containing the older CR9000-series dataloggers. I/O modules
other than the CR9080 can be used with either the CR9000-
series or CR9000X-series dataloggers. CR9000 communication
interfaces (i.e., NL105, BLC100, TL925, PLA100) are not compat-
ible with the CR9000X series, and therefore have been retired.
RTDAQ software is not compatible with the older CR9000-
series dataloggers. Customers can upgrade a CR9000 or
CR9000C to a CR9000X or CR9000XC by replacing their CR9031
CPU module with a CR9032 CPU module.
