These low cost, sealed platinum surface RTDs
are the world’s toughest.

The IEC 751 sensor is refractory sealed for ±0.05°C stability. Its small strong design allows this package to conform on curved surfaces for accurate response in milliseconds. Leads welded within the sealed RTD provide this sensor’s durablity. Moisture resistance for condensing environments or shallow immersion is provided by Kapton®/Teflon® lamination that completely encapsulates the assembly and lead entrance. Standard operating range is –200°C to 260°C. Clamped sensors can withstand 315°C.
