RdF offers a broad range of Cryogenic RTD Probes for ground support and flight. We tailor designs and qualify sensors to meet varying performance requirements and environmental conditions for each program. RdF RTDs have served on every manned US Space Mission since Project Mercury.
Cryogenic RTDs for Aerospace often have application-specific demands that are met with different design options. These particulars will vary and should be discussed with RdF to identify the right sensor. Examples of such considerations are:
• Dynamic Requirements, shock vibe and flow
• NIST Traceable Cryogenic Calibration for High Accuracy Control Points

RdF maintains a NIST-traceable calibration facility to support the high accuracy requirements of our Research, Defense, Aerospace and Nuclear customer base.
For many applications, RdF recommends a standard three-point calibration at Liquid Nitrogen, 0°C and 100°C to provide reliable and repeatable measurements ±1.1°C over a wide range.
For customers with super high-accuracy sensing needs, RdF Corporation offers multipoint cryogenic calibration services and individualized Resistance v Temperature profiles in the cryogenic range for each probe. Calibration points can be customized to application-specific control points.
Using our NIST-Calibrated Cryogenic Standards, RdF’s calibration process yields RTD Probes with accuracies ±0.14°C, high interchangeability, and extremely stable, repeatable performance.
RdF Aerospace Legacy
Founded in 1955, RdF has supported space exploration since the inception of the United States Space Program. RdF sensors have served on every manned U.S. space mission since Project Mercury.
Their qualified temperature sensors are orbiting on the ISS, satellites, and telescopes, installed in ground support facilities, and monitoring critical systems on launch and crew vehicles currently in production.
Today, RdF continues to work with companies worldwide to advance the exploration of Space. To discuss your project or learn more about RdF’s Cryogenic Capabilities, please speak to one of our engineers.
