Rotation Speed Indicator
Rotation Speed Indicators
By setting on a handle or shaft, a rotation speed can be specified. There are a "Weight type" with movable needle and "Differential type" with movable dial. It has high functions with artistic appearance.
Use these indicators to show RPM by mounting them on the handle or shaft to be read. On the weighted model, a needle moves, while on the differential model, a dial moves. These indicators are not only accurate, they are also attractive, improving the appearance of machinery.

- SD Differential Models
Use these indicators to show RPM by mounting them on the handle or shaft to be read. On the weighted model, a needle moves, while on the differential model, a dial moves.
Weight Type
A dial is integrated with the inside weight, and it is always at a fixed position by a pendulum principle. When rotating the case, a short hand rotates by decelerating through the inside gear. A short hand indicates 360 deg. x rotation ratio per rotation of the case. A long hand is integrated with the acrylic plate, and it indicates a rotation angle when rotating the case.
SD-38/53/75 (Indicator Only)
A stand-alone model is classified into 38, 53 and 75 according to the outside diameter. The size 38 is an integrated model with handle that is used by mounting directly on a rotating shaft. The size 53 and 75 can not be mounted directly on a rotating shaft that the design of handle part is necessary. A handle set model is also available. Each type has 1 or 2 indicator needles. The appropriate type can be selected from a variety of products in rotation ratio.

SD-53/75 (Combination with Handle)
This is a model with satisfactory design and function adding a handle part to the stand-alone model SD-53/75. A large variety of handle outside diameters from 66mm to 250mm are available. A performance of the index part is the same as the stand-alone model. The appropriate type can be selected from a variety of products in rotation ratio.
| Rotation ratio |
1/4 to 1/64 |
| Outside dia. |
66,80,140mm/SD-53, 125,180,250mm/SD-75
|
Differential Type
By rotating the main moving case, a pinion gear rotates in a circle astride both internal gears that have the same pitch circumference and different teeth number. When the main moving case makes one revolution, a rotation angle differential for teeth number differences of two internal gears is generated. A dial moves for a certain angle to indicate the value at a mark position of the fixed case.
SD-50/100 Model
When rotating the rotating shaft, the dial rotates in the same direction. A clockwise or counterclockwise type is selected for a dial. A dial without a scale is also available for writing a scale freely. Unlike the weight type, the indicator can be mounted freely in any direction.
| Rotation ratio |
1/20,1/25,1/50 |
| Outside dia. |
50mm,100mm |
