Hello Sir,

 

I am using SR11-05 sensor in the first

The information of sensor:

Calibration result: - sensittivity: S= 20.67 x 10^-6 V /(W/m2) ; Calibration uncertainty +- 0.28 x 10^-6 V /(W/m2)

In this case, Can i use the formula " scale factor = 119.21 / Calibration sheet number" ? 

(S = 119.21 / 20.67 = 5.76; offset=0)

 

Please help me

 

Thank you very much

Hello Vinhquyen,

 

Thank you for your post.

 

To properly scale thermopile sensors you need to consult the "Scaling_Thermopile_Sensors_AppNote.pdf". I'm not attaching it here because the information may change overtime and post may not be updated with the most recent version. Please refer to our website or email support@rnrgsystems.com for a current copy.

 

With a Hukseflux SR11, you'll need to use a "SCM Constant" of 29.875 and divide by the sensors calibration (sensitivity) value.

 

Scale Factor = SCM Constant / Sensitivity.

 

Scale Factor = 29.875 / 20.67 = 1.445.

 

The offset will be 0.

 

Please contact support@rnrgsystems.com with any further questions.

 

Thank you!

 

Pearse
