The 29309 surface platinum RTD capsule temperature sensor series from RdF offers small strong design which allows this package to conform on curved surfaces for accurate response in milliseconds. These surface temperature sensors offer a long term stability better than ±0.05°C per 5 years. Available with sensing element resistance of 100Ω or 1000Ω with an IEC 751 Class A or Class B accuracy. The 29309 series offers a response time of 0.3s in water flowing at 3ft per second. they offer an operating temperature range of -50°C up to +232°C (or up to +260°C in dry applications). The leads are welded within the sealed platinum RTD sensor which helps to provide this sensor’s durability. Moisture resistance for condensing environments or shallow immersion is provided by Kapton®/Teflon® lamination that completely encapsulates the assembly and lead entrance.
