Vehicle Monitoring and Testing

 e versatile, rugged design and low power requirements

of the CR9000X-series dataloggers make them well

suited for vehicle monitoring.  ey excel in cold and

hot temperature, high altitude, o -highway, and cross-

country performance testing.  e CR9000X series is

compatible with our SDM-CAN interface.

Compatible sensors o en used for vehicle monitoring

and testing include thermocouples, pressure transduc-

ers, GPS receivers, pulse pick-ups,  ow transducers,

potentiometers, strain gages, load cells, digital switch-

es, 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, de ection, ride

• Fuel system—line and tank pressure,  ow,

temperature, injection timing

• Comfort control—ambient and supply air tempera-

ture, 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

Other Applications

• Aerospace/aviation—can endure the rigors of

space travel and provided acceleration, structural,

and equipment performance measurements.

• Geotechnical—measures tilt, convergence, displace-

ment, 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.

Vehicle monitoring includes not only passenger cars but loco-

motives, airplanes, helicopters, tractors, buses, heavy trucks,

drilling rigs, race cars, ATVs, and motorcycles.

Our dataloggers measured the e ects of gravity on a

test structure aboard a NASA low-gravity  ight.

Compatibility with

Retired Products

Customers can add CR9000X-series dataloggers to

networks containing the older CR9000-series dat-

aloggers. I/O modules other than the CR9080 can

be used with either the CR9000 series or CR9000X

series. 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. Customers can

upgrade a CR9000 or CR9000C to a CR9000X or

CR9000XC by replacing their CR9031 CPU module

with a CR9032 CPU module.
