SPECIFICATIONS

PARAMETER	SPECIFICATION	COMMENTS
USB Input	USB 2.0 500mA	Must be powered hub if used
Analog-to-digital converter inputs	24 bit ADC	Configurable gain
Usable range	±18V	Output can be calibrated for greater accuracy by user
Absolute maximum input	±30V	If inputs above 18V readings on other channels become innaccurate
Resolution	<100uVRMS	With 0.1 second ADC sample time – better with additional digital filtering
Input impedance	50kohms	Input circuitry for bipolar inputs, output of instrumentation must be able sink a small amount (100uA) of current
Thermocouple input*	K type standard	Other types can be plugged in with less accuracy. Software contains polynomials for J, K, T types
Power supply output	Programmable ±5 to ±24V	Negative supply is unregulated and will vary more with no load. Positive supply must have a load.
Power supply current	1.5W total power	1.5W maximum. For example, can use only +15V@100mA, or ±15V@50mA
Digital filter	Single pole IIR filter	Software configurable
DAC output	0 - 3.3V, 12 bits	Output may not go all the way to 3.3V. Typical 3.2V maximum
I/O bit	3.3V	Configurable for input or output
Sample rate – embedded	4 milliseconds per enabled channel minimum	Overall sample rate depends on number of enabled channels and ADC rates
Sample rate – PC	0.1 sec	Minimum
Software requirements	Windows 2000 Service Pack 3 or later	Comes with driver so that a simple terminal interface can be used
* Thermocouple not included	Specifications Subject to Change without Notice

 

 

 

EXTREME SENSORS

 

 

DECLARATION OF CONFORMITY

 

 

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.
