Platinum temperature sensor in thin-film technology M 310
M-series platinum temperature sensors are characterized by long-term stability, excellent precision over a wide
temperature range and compatibility. They are used particularly for applications with high consumption volumes, typically in
the automotive, white goods, HVAC and energy generation industries as well as in medical and industrial appliances and
machinery.
The measuring point for the nominal resistance is defined at 8mm from the end of the sensor body.
