Cobalt RTDs
Platinum cobalt resistance temperature sensors are specifically designed for cryogenic applications.
The PtCo100 element has higher sensitivity at cryogenic temperatures compared to a
standard Pt100, resulting in higher resolution at extremely cold temperatures. Low hysteresis is
accomplished via a highly engineered sensor coil configuration, designed to securely support the
sensing wire while minimizing thermal expansion measurement errors.
The standard resistance value is 100 ohms nominal at 0 °C, with a temperature coefficient of 3376
ppm. Other resistance values are available upon request, subject to minimum order requirements.
The PtCo temperature sensor is suitable for an operating temperature range of (-270 to +200 °C).
