PTF Family Platinum RTD Sensor
Brand: American Sensor Technologies IncThe PTF Sensor Family combines a group of resistance temperature detectors (RTD) using a Platinum resistor in thin film technology as sensing element.
It 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 characteristic curve of this Platinum RTD complies with DIN EN 60751. The usage of Platinum as resistive material guarantees high long term stability. 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.
