The KD-5600 Family provides a 2-channel, digital, high-resolution differential measuring system that measures tilt-tip/differential position with nanometer accuracy. Typically, two sensors are placed on opposite sides of a target or target pivot point. For tip-tilt positioning, four sensors are used. Kaman uses an auto-calibration station to significantly reduce the cost and time required for calibration during system set-up. The digital output is designed to reduce susceptibility to signal drift and noise compared to similar analog-output systems. The KD-5600 operates with an input voltage of 8 – 30 VDC, making it compatible with modern data collection and processing systems.
KD-5690 FE (Front-End)
Provides direct access to both the analog and digital output signals, simplifying system set-up. Sensor null and offset can easily be verified using a voltmeter before switching to digital operation. The KD-5690 digital signal goes directly into the customer’s FPGA, providing high-speed signal linearization and temperature compensation, and allowing for oversampling to increase resolution.
KD-5656 (Full System)
This digital system is designed to interface directly to an embedded controller with a Master SPI bus. It then outputs two 24 bit digital words, one for CH-X and one for CH-Y each time the data is received and can linearize the sensor signal to as low as 0.04% FS and outputs the signal in engineering units. The KD-5656 is ideal for condition monitoring and preventative maintenance, with features including data file storage, event triggering, and in situ recalibration.

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