WebFeb 27, 2015 · The overall gain of the ADC is a function of the reference voltage along with a multiplication factor, K. This multiple factor varies from device to device. For example, the maximum input range of the … WebThe governing equation for this is: E emf = −S∆T = S (T HOT − T COLD ), where: E emf is the voltage output of the thermocouple. S is a temperature-dependent material property, known as the Seebeck coefficient (For a type K thermocouple, this is roughly 4.1 μV/°C between 0°C and 1000°C) T COLD is the Temperature of the Cold Junction.
WebThe digital output is the compensated hot-junction temperature measured by the thermocouple. The guaranteed temperature error of this device is within ±9LSBs for hot-junction temperatures between 0°C to +700°C. Although this device can measure a wide range of hot-junction temperatures, it cannot measure temperatures below 0°C. Figure 4.
