EMC

EN 55011:2007 – Class A Group 1 Radiated Emissions Requirements

LVD
EN 61010-1:2001 The KD-2306 unit requires the use of a limited energy power supply circuit per EN 61010-1:2001 Article 9.3. The KD-2306 does not use or switch voltages in excess of 60 VDC or 42.4 VAC peak (30 VAC rms).

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, 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
When the standard thermal sensitivity of 0.1%FS/°F is not enough, a temperature compensated calibration can be performed that will improve the thermal sensitivity to 0.02%FS/°F. This is accomplished over a customer specified 100°F range with the upper limit of that range <150°F. Larger ranges and higher temperatures are also possible on a best effort basis.

Output
Besides the standard 0-10VDC output, the KD-2306 offers a 4-20mA output and a differential 0-10VDC output.

Synchronization
When multiple channels are used in such a way that the sensors themselves are in close proximity to each other (within 3 sensor diameters), synchronizing the oscillators of the electronics modules will eliminate the resulting beat note interference that will be seen as noise on the outputs.

Log Amp Bypass
When extremely short range calibrations are required/desired, bypassing the log amplifier reduces noise improving performance.
