Part 5 - Synchronizing Multiple KD-2306 Systems
When sensors are used in close proximity to one another, performance will be compromised unless
the control units are synchronized. Performance degradation is due to interaction of the sensor fields
and is likely to appear as a low frequency oscillation on the output signal. In general, sensors located
adjacent to each other with less than 2-sensor diameter spacing will require synchronization.
Contact Kaman Precision Products if your KD-2306 systems require synchronization.
Part 6 - System Modifications
6.1 Temperature Compensation
While inductive sensors offer advantages over competing technologies, one of the limitations of this
technology is output drift due to varying temperature at the sensor location. The effect of temperature
changes can be minimized, but not totally eliminated.
Note that the temperature changes referenced apply to the sensor only. The control module must be
maintained in a temperature stable environment within the temperature band specified.
Thermal sensitivity shift for a standard KD-2306 system is 0.1% of full-scale output per deg F (0.18%
per deg C). A system can be temperature compensated to reduce thermal sensitivity shift to 0.02%
of full scale per deg F (0.036% per deg C).
This procedure must be performed at the factory as it involves component changes to the circuit
board. Temperature compensation is not recommended for temperature variations less than 18 deg
F (10 deg C).
