Help with Calipers specifications:
Caliper Type
Back to Top
|
| ||
| Your choices are... | |||
| Center Measuring | Calipers with conically pointed jaws are designed to measure the distance between the centers of two holes. | ||
| Gear Tooth | Calipers with an adjustable tongue are designed to measure the thickness of gear teeth at the pitch line. The adjustable tongue sets the measurement depth at the pitch line or addendum. | ||
| Machine Travel | Gages or gaging systems are designed to measure the travel or position changes of a machine bed, table, or stage. Micrometer heads, indicators, specialized calipers, and other OEM gages are used for machine travel indication. These gages are typically mounted on a machine or are built into a product including machine tools, microscopes, and other instruments requiring precision dimensional measurement or position control. | ||
| Nib Jaws | Nib shaped jaws facilitate the measurement of inside features (ID), outside features (OD), grooves, slots, keyways or notches. Compared to the blade edge typically found on standard calipers, the nib is more easily and accurately located on an edge or groove. | ||
| Pocket / Rolling Mill | Small, pocket-sized calipers are usually designed for low precision gaging applications. Rolling mill calipers are usually simple rugged devices for quick gaging of stock in production environments. | ||
| Slide Caliper | Sliding calipers use a precise slide movement for inside, outside, depth or step measurements. While calipers do not typically provide the precision of micrometers, they provide a versatile and broad range of measurement capability: inside (ID), outside (OD), depth, step, thickness and length. Slide calipers are available with direct reading or Vernier graduation as well as dial or digital displays. | ||
| Spring / Firm-joint | Spring, Fay, firm-joint or other radially opening type calipers have jaws that swing open with a scissor or plier-type action. These calipers are commonly found in nongraduated versions; although units with graduated, dial, or digital displays are available. Spring or firm-joint type calipers without displays or graduations are typically used for comparative gaging and the transfer measurements for layout purposes. | ||
| Other | Other unlisted, specialized, or proprietary caliper types such as gages with diametrical scaling, specialized jaws, etc., tailored for specific applications (recess, groove, or offset). | ||

Measurement Scale

|
|
| ||
| Units: | |||
| Your choices are... | |||
| English | Gages and gaging systems are based on the English system of measurement (e.g., inches). | ||
| Metric | Gages and gaging systems are based on the metric system of measurement (e.g., centimeters, millimeters). | ||

| |||
| Display: | |||
| Your choices are... | |||
| Dial / Analog / Direct Reading Scale | Devices include dial displays, column/bargraphs, and direct reading scales. Dial displays use a pointer or needle mounted in a graduated, disc dial. The dial provides an indication of dimension or position around or from a zero reference point with dial graduations or styles, such as 10-0-10, 45-0-45, 4-0-4 or 50-0-50. Column and bar graph displays provide a graphical presentation of dimensional data. Direct reading graduated scales have rulings or graduations engraved or printed onto a linear, disc, or drum surface that provides a direct indication of the gaged dimension. Vernier scales provide additional amplification or an increased level of precision (e.g., thousandths). | ||
| Digital Display | Digital display types present metrology data in numeric or alphanumeric form. Micrometers, calipers, and indicators are available with digital displays. Gages with digital displays often have data output capabilities using serial or other formats. Digital readouts are a precision type of digital display integrated into dimensional gages or systems. | ||

| ||
| Range: | The total range length or dimensional range that gages can measure. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Graduation / Resolution: | The best or minimum graduations for scaled or dial-indicating instruments, or the best or minimum resolution for gages with digital displays. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||

| ||
| Depth Attachment / Gage? | Gages are used to measure depth. Depth gages usually consist of a solid base with a protruding rod or slide. The solid depth base provides a reference and support across the opening. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Marking Capability | Gages accommodate a scribe or other device for accurately marking a component at a specific measurement along a particular dimension. | ||
