Three transducers and a signal conditioner built by Whittaker Corp. for the temperature measurement system of the Apollo Command Service Module, which would be used to capture telemetry (in this case temperature) from various points in the spacecraft. The three transducers have probes at the ends of long, coiled white wires, and the signal conditioner is capped at both ends. Housed in three plastic cases, with some calibration tags included. Accompanying paperwork gives manufacturing dates between August 1967 and March 1969.
