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.
The Original and first self-shielding eccentrically pivoted mechanism for aircraft applications. High torque, heavy eddy-current damping, and low relative inertia provide excellent performance characteristics, especially where influences of vibration and changes of pointer indications are significant factors. Custom pointers available upon request.
Has similar features as the 208 with the addition of size and versatility. It utilizes a single magnet circuit and two independent coils to provide two display functions from the same mechanism. Insolated solder terminals. Custom pointers available upon request.
Hi-Torque II has similar features as the 201. Increased magnetic field strength and the available space for wire turns on the moving coil provide a torque increase of approximately 46% that enables the mechanism to handle strut lengths of about five inches. Custom pointers available upon request.
Operates long and heavy pointers. DC self-shielding machine core-magnet construction ensures high torque up to 60 degrees of deflection. The 9071 meets the unique requirements of suppressed movement applications. Custom pointers available upon request.
Designed and manufactured in conformance with MIL-PRF-10304 (not QPL listed). Ideal for communication or test equipment where severe environmental conditions are encountered. MR34 Long-scale panel meters are ideal for military and commercial applications. Available 1.5″ (MR13), 2.5″ (MR26) and 3.5″ (MR34 & MR35)sizes.
The MODUTEC BL Digital panel meter gives you all the functionality you need with none of the extras you don’t need. That means simplicity, easy readability, a small footprint, and a low cost.
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.
The pointer type frequency meters, FM 48/72/96/144 are housed in molded polycarbonate cases are suitable for the measurement of frequencies in the range of 45 to 450 Hz. For maximum accuracy, the essential measuring range is obtained by suppressing the unwanted frequency span. These instruments offer several advantages in switchboard and generating set panels. A number of meters can be mounted in a panel cut out (mosaic mounting). The front glass, bezel, and dial can be easily replaced.
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.
The Jewell window mount 80 series analog panel meter is designed with a crisp appearance and high visibility. Only the clean lines of the dial face appear on your panel front, providing maximum layout flexibility. This unique space-saving meter saves up to 3 cubic inches behind the panel when compared to “barrel type” meters.
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.
Edgewise meters mount vertically or horizontally with a curved (13) or flat (13F) front. 5% Accuracy meters incorporate a moving magnet mechanism. Available size 2″.
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.
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 digital panel meter has been designed for industrial applications, which frequently require precise, onsite adjustment of the display range. It can be used in industrial automation and for laboratory uses. DPM EINE measures important electrical parameters in 3 phase 4 wire, 3 phase 3 wire, and single phase network replaces the multiple analog panel meters.
