te.com PTF FAMILY Platinum Thin Film (PTF) Temperature Elements Description The PTF family combines a group of resistance temperature detectors (RTD) using a Platinum resistor element utilizing the latest in thin film technology. It consists of a structured platinum film on a ceramic substrate, passivated by a glass coating. The connection wires are protected with glass on the welding area. The characteristic curve of this Platinum RTD complies with DIN EN 60751. The usage of Platinum as the resistive material provides excellent long-term stability. Due to small size and low mass, this RTD has a fast response time and low time constant therefore, it is an optimal solution for fast and precise feedback control systems. Features Conforms to DIN EN 60751 Wide operating temperature range: -50C to +600C (Ni/Au wire and Class F 0.3, Ag-Wire versions are limited to 300C) Standard nominal resistances values: R0: 100 and 1000 (others available upon request) Class F 0.1 (T = AA), F 0.15 (A), F 0.3 (B) and F 0.6 (C) accuracy Very low drift over lifetime Fast response time due to low thermal mass Variety of outline dimensions available to fit a wide range of space requirements Global interchangeability Applications Temperature feedback control White goods Industrial applications Automotive Medical Sensing element for plug-in probes CLICK HERE CONNECT WITH A SPECIALIST TE CONNECTIVITY SENSORS /// PTF TEMPERATURE ELEMENTS REV A3 10/2020 Page 1 PTF TEMPERATURE ELEMENTS Datasheet *Operating temperature range is, -200C to +600C for elements with Au-coated Ni wire. Max temperature for elements with Ag wire is 300C. Accuracy is not guaranteed if the sensor is exposed to temperatures outside the specified operating temperature range.
