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 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.
Windo-mount™ is a sophisticated design that has been found universal acceptance since being introduced many years ago by Modutec. The W series meters are easily installed per applications bulletin AB6-1; when so installed the meter cover is flush with the panel surface, with the dial easily read.
W series meters are available in the same ranges and at the same prices as the S series meters. They offer an excellent functional appearance, plus the looks enhancing edge options available. These meters are very popular for stereo and broadcast equipment.
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.
The Modutec 1000 takes the guesswork out of reading a small, low-cost, digital panel meter. These meters have an over-range indication of the rated value and auto-zero when there is no input signal. They also feature auto polarity which visually clues the user to a negative reading.
The Modutec 1000 features a 0.3-inch digit display in red or green for hard-to-read applications. Choose from bezel or window mount snap-on bezel – neither of which need extra hardware or panel holes. At 1.34″ x 0.75″ and panel depth less than 0.8″ these meters are easy to read, small units that fit into almost any application.
The moving coil panel meters DS 48/72/96/144 are housed in cases made of molded polycarbonate and are suitable for the measurement of DC current and voltages. These instruments offer several advantages in switchboards 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 all easily be replaced.
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) – 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 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.
The digital panel meter, DPM 48×96 has been designed for industrial automation and laboratory uses which frequently require precise, onsite adjustment of the display range. With versions available for current (A, B), voltage (C, F) sensors, this panel meter is a cost-effective choice for virtually all switchboard instruments.
*Note: Models AC & T no longer available.
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 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.
