| Experienced Member    |  Matching Thermopiles For Horizon Sensing Hi. DOes anyone know how to match thermopiles for horizon sensing? THe datasheets seem to specify fairly wide tolerances and due to the non-linear curves and expensive cost of the thermopiles (I can't buy 30 of them and then test them all), I am not sure how to match them. http://www.melexis.com/Sensor_ICs_In...sor_IC_19.aspx It seems the sensitivity tolerance is +/-25% which is quite a bit. If it tracked between units things would be fine. But do they? I do not know the details about thermopile manufacture. |
