White paper: how to achieve optimum sensor read out
Exergen IRt/c sensors are small, passive devices with very high performance levels. The passive nature of the IRt/c’s results in very small repeatability and interchangeability errors, and an unprecedented long term stability. These properties are essential for their use in OEM manufacturers, who aim to build machines that function consistently and predictably.
There are no any active processes in the sensor such as signal amplification or AD conversion. As a result, the sensor generates a non-linear, high impedance thermocouple signal that differs slightly from conventional thermocouples. Without an accurate and reliable readout process, the accuracy and consistency of the sensors could be impaired by readout errors.
This white paper explains how to select readout devices, and how to design readout electronics, for optimal sensor readout.
