Jewell Instruments manufactures and markets a broad range of JEWELL brand pointer mechanisms ensuring that we will meet your specifications. We have a variety of designs available. Below is a selection of our most popular pointer mechanisms. We have engineered these models to meet or exceed a variety of application-specific needs.
Series 802 are very small, low-cost, uncalibrated devices for indicating on-off conditions or voltage transition points. They are rugged, dependable, and require less than 2mW to move the flag or pointer. The two types are:
Flag Type (802F)Â – A white flag moves from one end of the red & white scale to the other when a predetermined voltage value is exceeded. Provides on-off indication.
Pointer Type (802P) – A pointer moves across the scale to indicate circuit condition. The pointer may be factory set for left, right, or exact center position to indicate zero current. The center point can be specified for a given voltage (±5%) within the range of the device.
Either type can be made to operate with a Zener diode to indicate voltage changes as low as 1 volt.
You need flexibility. We provide it. We customize our meters to meet your specifications.
The Jewell surface mounted 50 series analog panel meter is designed with traditional black case and glass windows. Black phenolic Bakelite covers and cases suited for industrial equipment. Available in both round and square shapes.
The Jewell DPM 72×144 4½ digit panel meters have been designed for industrial applications which frequently require precise and on-site adjustment of the display range. They are available in DC or AC current or voltage ranges. For use in industrial automation and for laboratory uses.
Jewell Instruments has been one of the leading manufacturers in the world for Meter Movements of all types for over 60 years. We have supplied our products to the Army, Navy, Air Force, Coast Guard, and Marine Corps as well as a wide array of military and aerospace customers. Jewell Instruments manufactures a variety of custom assemblies and special instruments combining Jewell Mechanisms and Jewell or customer furnished housings.
The S Series Surface Mount Panel Meters are clean-cut meters with straightforward design and pleasing aspect ratio are leaders of the Modutec line and add distinction to any instrument or control panel. Available in five sizes and a wide variety of types and ranges, they resolve many problems for the equipment designer and are always a solid choice for function and appearance.
AC Meters in this series are available in both moving coil (rectifier type) and iron vane versions. The latter has the virtue of being relatively insensitive to input distortion, while the rectifier type is less affected by frequency variations.
.5E Thermoplastic front and steel back. Horizontal mounting. Available size less than .5″.
The Jewell surface mounted MS Series analog panel meter is designed with a contemporary concave cover to reduce glare and improve readability. Rugged and durable, this aesthetically pleasing rectangular shape interfaces with today’s high technology applications.
Available in sizes 1.5″ up to 3.5″.
The moving coil, rectifier panel meters DGL 48/72/96/144 are housed in polycarbonate cases and are suitable for the measurement of AC currents and voltages. Moving coil rectifier instruments measure average values and are calibrated to indicate RMS values, assuming a sinusoidal waveform for frequencies from 40 to 10000 Hz (AC current – 40 to 1000 Hz and AC Voltage – 40 to 10000 Hz). These instruments offer several advantages in switchboards and generating set panels. A number of meters can be mounted in a panel cutout (mosaic mounting). The front glass, bezel, and dial can be easily replaced.
Designed and manufactured in conformance with MIL-PRF-10304 (not QPL listed). Ideal for communication or test equipment where severe environmental conditions are encountered. Available size 2.5″.
The highly versatile Jewell surface and bezel-mounted 70 series analog panel meter provide maximum flexibility for selecting the size, type of mechanism, and method of mounting. The crystal clear cover is distortion-free and unaffected by aging. The clean, clear appearance of these meters blends with any color scheme.
The A&M Model 4951 power factor meters are designed to meet the requirements of MIL-M-19261 and MIL-M-16034. They are supplied as either self-contained or as a “matched-set” with the external transducer. In the external transducer configuration, the transducer is matched to the meter. Both configurations are sealed watertight.
