Platinum Temperature Sensor in Thin-film Technology MR 518 G
MR 518 G platinum temperature sensors are characterized by their small, drop-form design. They are also characterized
by high long-term stability, excellent precision over a wide temperature range and compatibility. They are used in the 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 8mm from the end of the sensor body
