Flag Mechanisms

Jewell Instruments manufactures and markets a wide range of Jewell brand flag mechanisms. We engineer them to meet your specifications. We have a variety of designs available -- below is a selection of our most popular flag mechanisms. Each model is uniquely designed to meet some of our customers' most frequent requirements.

JEWELL Model 202 -- Versatility

The unique construction of the Model 202 lends itself to numerous modifications in height, width and mounting configurations. JEWELL 202 also has dial mounting plate and various pointer options. It can be used in engine monitoring and fuel gauge applications. Other options include a ¾ inch hermetically sealed indicator to display trim, null-on, and other conditions.

JEWELL Model 215 -- Reliability

The self-shielding design of the Jewell 215 enables high torque-to-size ratio characteristics. The Model 215 is ideal for use in multi-element aircraft instruments. Its self-shielding design and high torque-to-size ratio make it ideal for control systems with functions such as alarm indications and null detection. A variety of flag types and pointers are available. The Model 215 is available with the servo-mount feature as well.

JEWELL Model 241 -- Spacesaver

The Model 241 is a sub-miniature core-magnet mechanism with a space-saving design. This unit is just 7/16 inch in diameter and may employ flag or pointer indicators. A variety of case configurations are available to meet specialized mounting requirements. It is also available in a sealed case - with various pointer and bezels.

JEWELL Model 9073 and 9076 -- High Torque Mechanisms

JEWELL 9073 & 9076 operate very long prime indicating flags with high moments of inertia. Our highest torque mechanisms, the 9073 and the 9076 offer maximum scale angles of 40° to 48° for linear or non-linear deflection. Typical applications include glide slope instruments, rate of turn indicators, and speed control mechanisms.

JEWELL Model 9004 and 9072 -- Versatile Low Inertia Mechanism

JEWELL 9004 and 9072 offer 100° deflection. They power one to four-inch indicating flags with low moments of inertia. Typical applications include course deviation indicators, rate of turn pointers and horizontal and vertical D-bars.
