CI Systems SR-800R
While the new calibration method is based on the original methodology, ultimately, it
is an improved way of maintaining traceability and calibration. For the new
calibration method CI Systems uses a new temperature probe design (the new
removable sensor is physically longer, placing it further from the relatively unstable
emitter edge) that provides for improved accuracy over the earlier models.
CI blackbodies support both calibration methods. The temperature probe in the
emitter in all cases is removable. One calibration option simply requires replacing the
probe with a newly calibrated one; the other option treats the probe as non-removable
and the blackbody system is calibrated using a CK800 calibration kit.
Please note that the two calibration methods, while falling within the overall system
uncertainty, are not directly interchangeable and in order to maintain traceability, one
of the two calibration methods has to be selected and used for the operational life of
the test set.
Similarly, calibration of the target sensor in differential blackbodies will be
accomplished in one of two ways:
1. Calibrate the target sensor in a differential manner using the CK800 calibration
kit. This is accomplished by inserting the probe into a supplied copper block and
comparing it to the new master sensor with the copper block stabilized at ambient
temperature. The offset between the two sensors will be referenced out for the 0-
50ºC temperature-range. Note that this method is only accurate for typical
ambient temperatures of 20-25ºC.
2. When calibration is due, simply replace the target sensor with a new calibrated
removable probe.
When a blackbody is due for calibration, CI Systems is supplying this calibration kit.
For customers utilizing the newer removable probe methodology, CI is supplying
either one or two (for differential blackbodies) calibrated temperature sensors.
For customers who prefer to continue utilizing the older "fixed probe" calibration
methodology, CI Systems is supplying the new calibration kit.
