MULTI-VIT: MULTI PURPOSE VARIABLE IMPEDANCE TRANSDUCER

Kaman Instrumentation's Multi-VIT displacement measuring system, the KD-2300, is a noncontact linear proximity measuring system. This easy-to-use system makes high precision static and dynamic measurements for product design, fabrication, process control, and inspection of metal objects. It replaces LVDTs, air gauges, dial indicators, and micrometers.

The system includes a sensor, power and output cable, and signal conditioning electronics package. Zero, gain, and linearity adjustments are provided on the electronics package. The output voltage of the system is proportional to the distance between the face of the sensor and any metallic (conductive) target.

Depending upon the system, the standard sensor cable length may be increased to a maximum of 30 feet (9.15 m). If special sensor designs or improved system performance are required, contact a Kaman Instrumentation application engineer for assistance.

Certain internal components in the KD-2300 family precisely match the signal conditioning electronics to a specific sensor and cable. To change the sensor size and/or cable length, a corresponding bridge card must also change. This is an easy task, requiring only a screw driver, that can be accomplished in a matter of minutes. Contact Kaman for the type of sensor/cable conversion you wish to make.

 

 

 

This graph shows what happens to such relative factors as stability, linearity, noise floor, and resolution as the target gets further away from the sensor.

As long as you stay within a sensor's specified measuring range, the change in these factors is held to a very workable 0.1%. In the first half of the range it is quite improved.

On the other hand, overranging the sensor significantly degrades performance though you can still get usable information.
