Product Information

Convert units (if required): If your bevel protractor allows measuring angles in different units, make sure you set it to the desired unit of measurement (degrees, radians, gradients) before taking the measurement. Rushing the Measurement: Taking measurements too hastily can result in errors. Take your time, be patient, and carefully follow the steps outlined to ensure precise angle readings.

In general, all protractors, regardless of the material they are built of as long as they are used for precise measurement and inspection applications, require calibration. At somewhere The divisions on the vernier scale will coincide with the divisions on the Main scale. this reading is noted as the Vernier scale reading. Swivel plate: The swivel plate rotates over the dial. This swivel plate has a vernier scale which is integrated into it. The total reading =the main scale reading + the number of the division at which it exactly coincides with any division on the main scale × least count of the vernier scale. Alternate Between Blade Sides: If possible, alternate between sides of the angle being measured by aligning the blade with each side separately. This can help identify any inconsistencies or symmetry issues in the angle.

Advantages of Bevel Protractor

While using a bevel protractor, it’s important to be aware of common mistakes that can lead to inaccurate measurements. By avoiding these errors, you can ensure more precise and reliable angle readings. Here are some common mistakes to watch out for: On the vernier scale, the 12 divisions represent 60 minutes (Like this 15, 30, 45, 60). For example, 12 divided by 60 equals 60 minutes. Applications [ edit ] Manual (1), and Mitscherlich's optical (2) goniometers for use in crystallography, c. 1900 Surveying [ edit ] Fowler: Fowler is a trusted manufacturer of precision measuring instruments, offering various bevel protractor models suitable for different applications. The Fowler 52-439-777-0 Digitronic Protractor and the Fowler 54-565-233 High Precision Protractor are well-regarded for their accuracy, ease of use, and versatility. Use a Light Source: Position the bevel protractor under sufficient lighting to clearly read the scale markings. Shadows or dim lighting can make it difficult to obtain accurate measurements.

Protractors containing gears, such as bevel protractors and digital protractors, as well as those whose materials are temperature sensitive, should ideally be calibrated annually from the viewpoint of someone who uses a protractor on a daily basis. Aside from these, frequently used protractors must also undergo annual calibration. The Vernier scales are fixed on the swivel plate, & it moves along the swivel plate. The Vernier scale gives the remaining angle in minutes. There are 60 minutes in 1 degree. It is added to the Vernier scale bevel protractor to increase the accuracy of angle measurement.Align the Blade: Position the bevel protractor so that the blade is aligned with the second side of the angle. Make sure that the blade’s pointed end is accurately placed on that side. A Sine bar is used to measure the angle of the given specimen accurately. It usually measures the angle of the specimen as well as locates the workpiece (specimen) properly to measure the angle of it. Since the spaces, both on the main scale and the Vernier scale, are numbered both to the right and the left from zero, any angle can be measured. The readings can be taken either to the right or to the left, according to the direction in which the zero on the main scale is moved. A bevel protractor is an instrument that is graduated spherical protractor with one pivoted arm that we use for making off the angles. Sometimes the vernier scales have an attachment for giving more precise readings. One end of the changeable Blade is bevelled at 45 degrees, while the other is bevelled at 60 degrees.

Overcomplicating the Process: Remember to keep the process of measuring angles with a bevel protractor straightforward. Avoid overcomplicating it by using unnecessary tools or techniques that can lead to confusion and inaccuracies. Bevel protractor or vernier protractor or micro protractor or universal bevel protractor is the most precision model of protractor. It measures down to 5 minute resolution (the smallest reading). This model is available in analog and digital version. The analog version employs a vernier scale.To obtain the angle more accurately, we will now obtain the remaining angle in minutes. To do this, we look at the line of the Vernier scale, which coincides perfectly with the line of the main scale. Setting up a bevel protractor correctly is essential to ensure accurate angle measurements. Here’s a step-by-step guide on how to set up a bevel protractor:

Now we see the value in the main scale which coincides with the zero of the vernier scale. The value which we read from the main scale gives the angle in degrees. Clean the protractor. Thoroughly wipe the blade clean using cleaning oil and solvents. Any dirt, dust, and excessive oil must be removed using a cleaning solvent and lint-free cloth. Any unnecessary foreign object must be removed. They are used for a variety of mechanical and engineering-related applications. One common use is in geometry lessons in schools. What is Bevel Protractor? Verify accuracy: To verify the accuracy of the bevel protractor, use a reference angle or a known calibrated angle. Place the protractor on the reference angle and compare the reading to the known value. If there is a discrepancy, consult the manufacturer’s instructions on how to adjust or recalibrate the protractor accordingly. where 'h' is the height of the slip gauges placed below the roller and 'L' is the length of Sine bar i.e. L=200 mm or 300 mm.

iGaging: iGaging is a brand that provides affordable yet reliable measuring tools. Their bevel protractor models, such as the iGaging 14-019 and the iGaging 14-010, offer good accuracy and ease of use at a more budget-friendly price point. Bevel Protractor - Has a swinging arm that can rotate up to 360° enabling angles to be read from two directions. Main article: Positioning goniometer A miniature electro-mechanical goniometer stage. This type of stage is used primarily in the field of lasers and optics. This dial scale is the main part of the bevel protractor. It contains the graduated scale of angle from a value of 0 degrees to 360 degrees. In this graduated scale, every tenth degree is numbered.
