One of the questions that customers may ask is “How hot does the sensor get?” With the ETA2, the temperature difference is set during calibration based on the application. While the temperature difference measured by the RTDs inside the sensor pins may be as high as 15 C, the actual surface temperature of the pins is much less. FM has measured the surface temperature of the pins and our approval states a maximum of 4 C (7.2 F) temperature rise.
