DataLITE Wireless Sensors & Systems

Quick and easy to set-up, DataLITE wireless sensors provide superb quality of signal and gives the test subject total freedom of movement.

DataLITE wireless sensors requires a DataLITE interface (receiver) as the interface to the computer and allows for up to 16 wireless sensors to be connected on a single channel with a range of up to 40m.

Electrogoniometer

Using the exact same technology as our world standard wired electrogoniometers for dynamic joint movement measurements of the wrist, neck, elbow, ankle, hip, knee or back.

Torsiometer

Single-axis Torsiometers are designed for measurement of rotations in one plane e.g. forearm pronation/supination or neck axial rotation. If the Torsiometer is bent in planes X-X or Y-Y the output remains constant. All Torsiometers function in the same way, the difference being physical size.

1Life test results have been collected by cycling the sensors through movements that would happen during everyday use. For example, placing a sensor on an adult elbow and moving from the neutral position to maximum flexion and back to the neutral position, the unit will function for typically 600,000 cycles.

Hand Held Trigger Switch

The Hand Held Trigger Switch provides the user with a very accurate solution of synchronizing DataLITE with DataLOG or other 3rd party systems, such as a Vicon or Qualisys motion-analysis camera based system.

Contact Switches

Contact Switches plug into an Electrogoniometer and for example, by attaching the Electrogoniometer on the ankle, and the Contact Switches on the foot. It allows the researcher to co-ordinate the gait parameters with the dynamic movement of the ankle joint.


Adaptor

The DataLITE Adaptor is used with a DataLITE interface to communicate with the following devices: Dynamometer, MyoMeter, Pinchmeter, ForcePlates and Load Cells.

The various load/strength data collected may be synchronized real-time with other DataLITE sensors as part of a complete DataLITE system. Interfacing is effortless as all the precision calibration data is pre-programmed within the microprocessor controlled units.

The Biometrics Hand Dynamometer utilises precision load cell technology to increase the sensitivity and accuracy of measurement of even very low grip strength forces. By using the industry standard Jamar design, exterior researchers can compare with standardized normative data.
