Many options are available to customize a standard digiVIT system to meet the exact needs of the application. The most popular are:

Sensor Cables

Sensor cable extension
Standard cable extensions are available in 1 meter increments to extend the standard 2 meter cables integral with the sensors to a maximum of 10 meters. If a standard extension cable will not suffice, call Kaman to discuss your particular requirements.

In-line cable connector splice
Many sensors come with integral sensor cables. Routing this cable in some applications is difficult and something you only want to do once. Including an in-line connector splice in the cable, near the sensor itself, allows for easy sensor replacement should the need arise.

Hermetic in-line connector splice
Some applications pass the sensor through a pressure boundary, most commonly a vacuum chamber wall. We offer an in-line hermetic bulkhead splice for these applications.

Special Calibrations

Range
Standard published ranges are based on meeting a set of performance specs. Custom calibrations are possible to meet specific application needs. Contact a Kaman applications engineer if a custom calibration is desired.

Target material
If factory calibration is purchased, and unless otherwise specified, nonferrous systems will be calibrated with an aluminum target, ferrous systems will be calibrated with a 4130 steel target. If your target material is significantly different in conductivity and/or permeability it may be best to calibrate using the same material as your target.

Temperature compensation
Standard factory temperature compensation calibration can be purchased and is performed on the test bench. If a specific output range and/or temperature range is desired, contact Kaman to discuss your particular requirements.

Output
Unless otherwise specified, the default output is 0-10VDC. Optional outputs include 0-5VDC, +/-10VDC, +/-5VDC, 4-20mA and 0-20mA.

*All items may not pertain to the digiVIT. Ask your Kaman Expert for more information.

Console software – Used to communicate with the digiVIT via the ethernet port and a PC.
Calibration record – An excel spreadsheet that is set up so users can log their calibration data and print out a calibration record sheet.
