3 Overview
Wedge feeler gage is used to measure the gap and pore size. Common structure types are wedge feeler type Ⅰ, Ⅱ type
Wedge feeler, Digital wedge feeler.
Ⅰ type wedge feeler is wedge-shaped flake, having a tapered angle, ulnar surface has an ordered set of scale marks and rulers
Digital, digital representation of the scale corresponding to the width of ruler marker position. Its structure type shown in Figure 1.
Type Ⅱ wedge feeler wedge block having a wedge angle, ulnar surface has an ordered set of scale marks and the number of scale
Word, the scale numerals corresponding mark position perpendicular to the measuring of the thickness of the substrate surface. Its structure type shown in Figure 2.
Digital wedge feeler gap known as the through-flow measurement scale, the use of mobile measurement head with digital display at the foot body
Relative motion in the form of digital display at the end face of the measuring head moving perpendicular to the surface of the wedge thickness measurement. The structure type
Type shown in Figure 3.
