PTF Family Platinum Temperature Sensors TE Connectivity's PTF Family Platinum Temperature Sensors are ideal for extreme temperature environments from -200°C to +600°C. The sensors combine a group of resistance temperature detectors (RTD) using a Platinum resistor in thin-film technology as the sensing element. The RTD features a small outline and low mass for a low time constant suitable for fast and precise feedback control systems. Applications include appliance, industrial, and medical markets. TE Connectivity PTF Family Platinum Temperature Sensors are compliant with DIN EN 60751.
