Cryo-con Model 24C Specifications, Features and Functions
Performance Summary
Measurement Accuracy
Diode Sensors
The formulas for computing measurement accuracy while using diode sensors are:
Where:
MAV is the electronic Measurement Accuracy in Volts
MAT is the Measurement Accuracy in Kelvin
SenRdg is the sensor reading in Volts at the desired temperature.
SenSen is the sensor sensitivity in Volts / Kelvin at the desired temperature.
For example, to calculate the measurement accuracy of the Model 24C using a Cryo-
con S900 sensor at 10K, look up the sensor reading and sensitivity in the S900 data
table in Appendix G. At 10K, SenRdg is 1.36317 Volts and SenSen is 0.002604
Volts/Kelvin . Therefore,
and
The result is MAV = 128V and MAT = 49mK.
