What new features can we imagine when talking about temperature measurement? This is well established and many solutions are available. However, there are points, which can be improved and simplified. With PS08 we introduce a solution for platinum sensors that combines a very low current consumption of a few µA with a high resolution of a few mK. Thanks to the minimized current in the sensor the self-heating effect is negligible. The integrated microprocessor can take care of calculating the temperature.

In this white paper we introduce an electronic for measuring the temperature, optionally with display, for a range from -50°C to 350°C. It is based on PS08 and offers 3 mK resolution at a current of less than 2 µA into the sensor.
