Apollo Ground Instrument Trainer Gauges (2)
Two Apollo ground instrument trainer gauges: an indicator gauge for "°F" and "PSIA," measuring 2˝ x 4˝ x 4.5˝, marked on the top, "Weston Part No. 248321, Serial No. 11," and labeled on the side: "For Use on Ground Instrument Trainer Only, Part No. 564423, Serial No. 10, Made in U.S.A., Link Div., General Precision Inc., Binghamton, N.Y."; and a small circular indicator, measuring 1˝ x 1˝ x 2.5˝, labeled: "For Use on Ground Instrument Trainer Only, Part No. 690720, Serial No. 35, Link Group, General Precision Systems Inc., Made in U.S.A., Binghamton, N.Y." The dual gauge indicator measuring temperature and pressure was intended to simulate monitoring of the Service Propulsion System (SPS) propellant tanks; the smaller dual position indicator the status of the SPS Injector Valve (open or closed). In overall fine condition.
