CLINOMETERS - TAYLOR HOBSON - #1

Clinometers are valuable for simple, speedy and accurate measurement, checking and setting-out of angles.

Workshop Clinometers are robustly constructed instruments, with scales designed for clear, simple reading. The digital clinometer is ideal for angu­lar settings, checking and inspection of machine tools and fixtures. Mechanical clinometers are also avail­able on request.

Microptic Clinometers have been designed for simplicity and very high accuracy. The Clinometer uses precise­ly divided circular glass scale, mounted on a spindle that rotates in a high quali­ty bearing. At the end of the spindle is a sensitive bubble vial, which acts as a horizontal reference.

Two models are available - TB80 and TB100 - both reading over a range 0°-360°.

Dual purpose

In addition to functioning as clinome­ters, both Microptic Clinometers can be used either vertically or horizontally as circular measuring tables. For this pur­pose the bubble unit is replaced by an optional worktable, which allows a max­imum symmetrical load of 2.25 kg (5 lb). A reflector can also be fitted for use in conjunction with an autocollimator.

• Direct reading to 1/2 second of arc.

• Two-sided circle reading system designed to minimise scale centring errors.

• A coincidence-reading bubble unit.

• Hardened and lapped steel locating faces on the base, one adjacent side, and the back.

To determine the inclination of the clinometer, the bubble unit is levelled and the scales read through the read­ing eyepiece. Fine setting of the bubble is achieved by a slow-motion drive to the totally enclosed glass circle.

The bubble unit incorporates a prismat­ic coincidence reader that presents both ends of the bubble as adjacent images in a split field of view. Precise levelling is indicated when the two ends are coincident.

The field of view visible in the eyepiece contains two scales. The lower one is the main scale, in degrees with 10 minute sub-divisions; above it is the scale of the optical micrometer, in min­utes with 10 sub-divisions.

Readings from the graduated circle and the micrometer scale are given in two separate apertures seen through the eyepiece.

This universal clinometer is ideal wher­ever a high accuracy is required over a large measurement range. The system offers the following features:

• Large measuring range (+/-45 degrees) accurate to within 2 minutes of arc

• resolution of 0.01 degree (in certain conditions 4 seconds of arc or 0.02mm/m)

• variety of measurement units (push button selectable) to give readings in degrees, minutes of arc, mm/meter, .001710 inches.

• Direct reading to 10 seconds of arc.

• Estimation to within 2 seconds of arc.

• Hardened ground steel base.

Automatic setting to absolute or relative zero measuring modes is selectable by push button. All four sides of the hard-anodized aluminium frame are preci­sion machined to make possible angle measurement in any quadrant. Battery power, sturdy construction and compact size make the devise suitable for use virtually anywhere. A built-in calibration program ensures that calibration is always current and correct.
