Differential resolution to a nanometer

  • Two precisely matched sensors per channel give resolution to a nanometer.
  • Superior thermal and long-term stability of 5×10-6 inches/month or better.
  • Small package size: 2 x 2.12 x 0.75 inches thick.
  • Cryogenic sensors available.
  • High sensitivity: up to 10 V/mil (394 mV/µm).
  • Low power consumption: less than 2W @ ±15 Vdc typical.

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

SENSOR CABLES
Sensor cable extension
Most sensors can handle longer cable lengths, although increasing the cable length can and will affect some performance specifications. Shorter than standard cable lengths are also available. Call an apps engineer 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
Unless otherwise specified, nonferrous systems will be calibrated with an aluminum 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.
