Panel Meters

Panel Meters from Jewell Instruments

For over 70 years, Jewell Instruments and our predecessor companies have provided high quality panel meter solutions for a wide range of aerospace, industrial and commercial applications.  Our Jewell Brands, Modutec, Emico, Triplett, A & M and Jewell, are well known for their high quality and reliability

Jewell Instruments is the best choice for both new and traditional analog and digital panel meter applications. .Jewell Instruments is the only panel meter manufacturer that offers the full spectrum of panel meters, including edgewise, round, square, rectangular, and din, in sizes from .5? to 5.5?. We offer AC and DC inputs which include µa, ma, amp, mv, volt, frequency, and vu, in too many ranges to list. We make panel meters that cover the range of application options.

  • Analog (Pivot & Jewel, Taut Band, Iron Vane, and Moving Magnet)
  • Digital (LCD and  Backlit LCD)
  • Switchboard
  • From 5% accuracy to 1.0% accuracy
  • Garden variety to highly customized

We can meet your requirements immediately. We have decades of broad-based experience resulting in our superior breadth of product and our ability to meet your custom needs. Jewell Instruments can provide a proven and cost-effective solution to your panel meter needs.

Some of our many customizable features include:

  • Custom Colors:   If you can reference a Pantone or PMS color, we can  match it.
  • Translucent dials:   Utilized for superior backlighting on some models.
  • Custom resistance:  This option permits variations from 70% to 200% of those figures, for accommodation with related circuitry.
  • Special Ballistics:  Some applications require faster response times than found in the standard meter. This option fills the need, with reduced damping factor. Standard meters have response times per ANSI Std. C39.1-1981, offering a response compromise between speed of response and overshoot. This option improves the response time to  approximately half the catalog specifications. Resistance of the meter may double. Consult us if further data on a specific type and range is needed. Extra time is required for this option, and it is only available on taut-band meters.
  • Custom pointers:  Catalog meters are standard with PB Lance pointers as standard. We also offer tubular, tapered V, and spade tip pointers in most colors.
  • High temperature case & covers:  Cases and covers of standard meters will withstand temperatures to 85°C. This option employs Lexan covers and special cases with ratings to 100° C and hot spot ratings to 110°C without damage. They are also ideal for any application where hotspot conditions are present in the equipment. (Lexan is a registered Trade Mark of General Electric Co.)
  • Custom Logo on dial:  80% of the meters Jewell manufactures leave the factory with someone else’s name on it. A one-time artwork and dial prep charge puts your company name where the world can see it.
  • Illumination:  Series S, W, and BA meters can be furnished with internal light wells, together with socket and bracket assemblies, hardware, and instructions for attractive, glare free illumination. This option is appropriate for sizes 2? through 5? and mounting cutouts remain the same for BA option and W series. S series meters require two additional clearance holes for the lamp sockets. Sockets accommodate midget grooved T-1 size lamps in all standard voltages: 6,12,28, etc.  Decreasing nominal voltages by 20% greatly extends lamp life with little loss in brightness.
  • Heavy damping:  Heavy damping is often required to minimize pointer motion where meter is subjected to mechanical vibration. This option subdues the motion with an increase in response time proportional to the amount of damping required. Standard meters have a damping factor of 2.5  minimum, 5 typical, in accordance with ANSI Std. C39.1. This option  provides considerably more damped performance with a damping factor of 10 minimum.
  • Sealed Case: This feature, which provides for complete sealing of the case, is ideal for humid, corrosive or dirt-laden environments or where the possibility of splashing is a problem.
