Leaded Platinum Temperature Sensor
PTL Temperature Sensors are the perfect choice for the
most fields of modern electronics. The highly controlled
platinum thin film manufacturing process guarantees an
outstanding stability of temperature characteristics. Typical
applications include temperature measurement in process
controls in industrial electronics, and precise temperature
measurement in medical equipment.
