NASA MSFC displacement sensors, calibration, and shipping for cryocooler testing

NASA Marshall Space Flight Center is seeking specialized displacement sensors and related calibration and shipping for cryocooler testing. - Buyer and location: NASA Shared Services Center (NSSC), for NASA Marshall Space Flight Center (MSFC); performance and delivery are associated with MSFC in Huntsville, Alabama. - Procurement approach: NASA intends to negotiate on a sole-source basis with Philtec, Inc., which the supporting justification identifies as the only supplier able to meet the technical and schedule requirements. The capability-statement notice requests capability information, not quotes, and says responses will help determine whether the requirement should be competed; this is a solicitation, not an award. - Products: Six Philtec RC31-Bv275-C1E1QT1 fiber-optic displacement sensor packages, or equivalents. Packages include probes, cabling, associated electronics for analog output, and CF275 ConFlat flanges. The sensors support rotor deflection and speed measurements during cryogenic testing. - Key requirements: Cryogenic and vacuum compatibility; operation from -280°F to 100°F for the probe and in-chamber cable; tolerance to vacuum through 125 psi; 0–5 V analog output; bandwidth from DC to at least 20 kHz; resolution of 0.5 µm or finer; and calibration certificates to Philtec’s published specifications. The SOW also specifies probe dimensions, standoff, signal range, and linear range. - Services and delivery: Calibrate five probes to a 0.4-inch-diameter round rotor target and one probe to a flat target; ship all deliverables to MSFC Central Receiving. The calibration and sensor deliverables are due within no more than 10 weeks, with shipping as each item is ready; the justification estimates delivery within 10 weeks after receipt of order.
