Description
Edcliff Instruments 7-11 Linear Accelerometer 0 to 17.5G Aerospace Sensor
The Edcliff Instruments Model 7-11 is a single-axis linear accelerometer with a measurement range of 0 to +17.5G, manufactured by Edcliff Instruments of Duarte, California. The unit features a machined aluminum cylindrical housing with a flat mounting face, six mounting screw positions, and a multi-conductor lead wire terminated in a 3-pin round connector. Wiring terminals on the mounting face are labeled 1, 2, and 3, with a +7.5 reference marking visible on the base.

Applications
Edcliff Instruments was a well-known manufacturer of precision inertial sensors and accelerometers serving the aerospace and defense industries from the mid-20th century. Linear accelerometers of this type were used to measure acceleration forces along a single axis in aircraft, missiles, spacecraft, and test equipment — including flight test instrumentation, inertial navigation systems, structural load monitoring, and vibration analysis rigs. The cylindrical form factor, flat mounting face, and screw-mount base are characteristic of sensors designed for integration into airframe or test-stand fixtures. Units like the Model 7-11 were used by defense contractors, aerospace research labs, and government test facilities during the post-war through Cold War era of American aviation and space development. Collectors and engineers working on vintage aerospace equipment, aircraft restoration, or test system refurbishment may find this sensor of interest for both functional and display purposes.
This Edcliff Instruments 7-11 Linear Accelerometer has been inspected and appears to be in good used condition. The aluminum housing is intact and shows light surface oxidation consistent with age. The green identification label on the front is present and legible. The rear label has significant wear and is largely illegible. The lead wires and 3-pin connector are present; the connector pins show some oxidation and surface wear. The bottom mounting face with terminal markings is intact. This unit has not been powered or tested at our facility but was pulled from an operational environment where it was previously in use.
