 EFFECTS ON OUTPUT
COSINE RESPONSE
Some of the radiation coming into a sensor at low angles is
reflected, which causes the reading to be less than it
should be. The cosine-corrected head helps to capture
radiation at low angles. The cosine error for typical
applications is less than 10 %.
TEMPERATURE RESPONSE
The temperature response is about 0.1 % per degree Celsius.
This temperature error is insignificant for most
applications.
LONG-TERM STABILITY
The output of all radiation sensors tends to decrease over
time as the detector ages. Our measurements indicate that
the average decrease of the sensor is about 1 % per year. We
recommend returning the sensor for
recalibration every 2 years. |
