METER MOVEMENTS
Self-Shielded Accu-Ring
Now standard in all series of panel meters. This completely self-shielded pivot and jewel
high torque movement is constructed with high density sintered iron ring and pole piece
which provides the best possible flux distribution through the entire 100 degree swing of
the coil. This unique feature coupled with the strong Alnico V Bar magnet offers exceptionally
high torque with minimum lag for fast response and quick, accurate readings, spring-loaded
jewels are standard for use in rugged applications. Virtually any damping and electrical
specifications can be met with a wide variety of bar magnets. Other features include all those
listed for the #17 external magnet movement. Hoyt Accu-Ring movement is standard in all
panel meter cases. The #22 movement is smaller, less powerful version of the #19
movement. Accuracy of 2% is standard. 1% accuracy is available in most ranges.
EXTERNAL MAGNET #17
These movements, accurate within 2% are built on the D’Arsonval principle according to the
best methods of meter manufacture. Features include Alnico V Magnets for high torque
movement, soft iron pole pieces electronically bonded to the magnetic system for long life,
microscopically inspected and selected jeweled bearings, hardened pivots specially
cemented and baked to short-proof anodized coil forms for trouble free life. Stong tubular
pointers-either lance or knife edgetypes, ceramic pointer stops, hair springs for quick
response and good damping are incorporated into all our movements. Spring loaded
jewels are standard with sapphire jewels available as an option.
AC REPULSION
Hoyt AC Repulsion movements are made with an accuracy of 2%. Jeweled bearings,
insulated or Bakelite zero adjusters, Hoyt cross arm balance, special constructed viscus
damping and choice of lance or knife edge pointers. The Hoyt AC Movements are man-
ufactured with brass movement support to match the moving element. This feature
enables the Hoyt AC meter to maintain accurate readings over a wider temperature range.
The AC meters can be used with corresponding size DC instruments where matching
meters are wanted.
250 DEGREE
The Hoyt once-patented 250 degree meter movement is a self-shielded pivot and spring
loaded jewel meter. Built for rugged industrial applications and shock resistant, this move-
ment incorporates precision aligned, mechanically interlocked construction with very high
torque. The movement is good down to 200 microamps with ample resistance. Airplane
or knife edge pointers are available in different lengths to accommodate a variety of
case styles and sizes.
3-1/2” Clear Plastic 2735/36 Meters
Model 2735/36, clear plastic meter with polycarbonate is
available in AC or DC. This unique case style yields
maximum visibilty and dust proof seal on the panel
surface. Three hole mounting on the meter front allows
for easy panel mounting.
