Product description

Information

Position indicators EN 000.8 have been designed for installation in various types of operating elements.

Housing, and all internal components are an one-piece, ultrasonically welded assembly. They are spray waterproof and corrosion proof (Protection class IP 67).

The gravity drive is mounted on ball bearings to give the most accurate reading, usable up to a shaft inclination angle of 60°.

The reduction gear ratio in the table shows the number of revolutions that are required by the long red pointer to make the small black pointer complete one revolution.

Function

Fixed firmly to the housing or the operating element, the pointer shaft with the longer red pointer is mounted at the center of the position indicator. This pointer therefore shows the revolution of the spindle at a ratio of 1 to 1, at the same time turning in the same direction as the spindle. The pendulum is positioned freely on the same pointer shaft, with the pendulum not turning in sync but always held in the same position owing to its force of gravity.
The scale and the gear wheels required for the desired reduction ratio of the second pointer are mounted on this pendulum. The rotary motion of the operating element is now transferred to the second, shorter pointer via a gear wheel fixed to the pointer shaft and via the reduction gearing at the fixed pendulum. Any position (rotary position) of the spindle can now be read with accuracy on the scale.

Use

The outstanding feature of pendulum-type position indicators is that the measuring system is fully integrated in the operating element. During installation, they require no further measures on the machine side.
In principle, these position indicators have been designed solely for attachment to horizontal spindles, but the high precision of the mechanical measuremen tsystem (the gravity drive is mounted on ball bearings) and the extremely lowcenter of gravity allow these to be used also for spindles inclined
by as muchas 60°.

Selecting the Reduction

While the longer red pointer shows the rotary motion of the spindle of a ratio of 1 to 1, the shorter black pointer makes only a fraction of the rotary motion defined by the reduction ratio.
The reduction ratio is selected depending on the maximum number of spindle revolutions over the entire range of adjustment. The preferred selection is the standard reduction ratio which is the same as or, if possible, slightly larger than the maximum number of revolutions.

Example:

Spindle adjustment range: 11 revolutions

Selected reduction ratio: 12 to 1

This selection gives virtually the whole scale range for the position indication.

Scale

The standard scales have divisions (number of graduation marks) matching the reduction ratio.
The numerical sequence also matches the reduction ratio depending on use, i.e. right turn (clockwise) or left turn (counter-clockwise).
If required and using a separately arranged table, the measured value corresponding the application in hand can be assigned to each scale number.
