Common Types Of Height Gages And Their Applications

height gages

With all of the types of height gages available, and with each of their matching applications, it might be hard to decide which one is the most appropriate for you. Which gage will meet your needs? The following will hopefully help you distinguish between not only the different types of height gages but the various purposes for which they were designed.

A General Look at Height Gages

Whether they were manufactured in 2002 or in 1902, height gages basically carry similar features such as the following:

  • Each possesses a vertical column. This column can be 36 inches long or as little as 6 inches long. Height gages with custom columns extend even further.
  • Attached to the column is a unit that slides down and up.
  • From the gauge, an arm protrudes. It comes directly into contact with whatever material you are measuring.
  • A solid base is featured by each and every height gauge and gives stability to the vertical column. It must, after all, remain (in relation to the table surface) at a rate angle.

The difference between height gages can depend largely on what kind of technology accompanies the above described basic features. Let’s take a look at some height gages and their differences.

Electronic Digital Height Gage

Not only are the measurements featured on a digital display, this height gage can have added features such as setting any position to zero, a hold option, and instant inch to millimeter conversion.

Digital Dial Height Gage

This is similar to the next gauge on the list but offers more precise measurements with a counter. Tenths of an inch can be read on the counter while one thousandths of an inch can be read on the dial.

Dial Height Gage

With a round dial attached to the slide, this is an analog reading unit. The user adjusts the position manually and the dial reads graduations of measurements.

Vernier Height Gage

Many refer to this height gage as old school. Featuring marks of measurement on both the arm and the vertical column, this is a unit with graduated scales. The most accurate height is indicated by the graduations lining up. For precise positioning, adjustments are made manually using a knob.

Height Gage Applications

Basic Height Gage Uses – To make sure they are within tolerances the basic use of a height gage is to check manufactured parts with sample measurements.

Scribing Material – Used for scribing material for later matching, this is a step up from the first basic use. After measuring, for later work, the material being measured would be marked.

Parameter Mapping – Slightly more sophisticated, the next use is taking a piece of equipment and mapping its parameters. The height gage can be used here by executing a two-axis measurement. This kind of measurement requires a special procedure and some new software programs have also come into use as of late.

Remember that Willrich Precision Instruments carries a wide array of height gages and an impressive inventory of measurement devices used in the metrology, gauge, and inspection industry.
