EN 61010-1:2001 The ThreadChecker unit requires the use of a limited energy power supply circuit per EN 61010-1:2001 Article 9.3. The ThreadChecker 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:
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, 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.
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.
Besides the standard 0-10VDC output, the KD-2306 offers a 4-20mA output and a
differential 0-10VDC output.
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.
When extremely short range calibrations are required/desired, bypassing the log amplifier
reduces noise improving performance.
