PTF- FAMILY Platinum Temperature Sensors Product Description The PTF-sensor family combines a group of resistance temperature detectors (RTD) using a Platinum resistor in thin film technology as sensing element. The characteristic curve of this Platinum RTDs are complying with DIN EN 60751. The usage of Platinum as resistive material guarantees high long term stability A platinum RTD consists of a structured platinum film on a ceramics substrate, passivated by glass coating. The connection wires are protected with glass on the welding area. The connection wires are gold coated nickel wire or silver wire. Gold coated Ni- wire is preferred for welding applications with need of higher application temperature but can be soldered as well, whereas silver wires preferably used for solder applications with lower temperatures. Due to small outline and low mass this RTD has a low time constant therefore it is a suitable solution for fast and precise feedback control systems. Platinum Temperature Sensor Sensors are packed as bulk goods in blister box.
