TE Connectivity's PTF family of platinum temperature sensors are thin film platinum RTDs with a fast response time and long-term stability for application temperatures from negative 50 degrees Celsius to positive 600 degrees Celsius. They provide high linearity, accuracy, and interchangeability, and are ideal for applications in automotive, industrial, medical, and white goods.
The sensors consist of a platinum film on a ceramic substrate with glass passivation and are available in four outlines with sensor lengths from 2.3 to 5 millimeters and you can get them with either gold-plated nickel or silver leads, with lead lengths up to 10 millimeters.
PTF platinum temperature sensors provide a fast response time, as low as 0.2 seconds to 90% of the final value in water, due to the small outline and low mass of the sensing element. This enables the use of control systems that require fast, high precision feedback.
They are also highly interchangeable, with tolerances from class F0.1 to class F0.6. This means there is very low sensor-to-sensor variation, and it guarantees that the sensor is within a certain tolerance at a given temperature, so there's no need to calibrate individual sensors. For example, the max variation for the class F0.3 sensor occurs at 600°C and is just plus or minus 3.3 degrees Celsius.
Sensors are available with nominal R0 values of 100 ohms or 1000 ohms and have a very low lifetime drift. For more information on TE Connectivity's PTF family of temperature sensors, visit Mouser.com.
