DP-XF-O Cheese yarn hardmeter
A, purposes and principles:
DP-XF-O spindles hardmeter suitable for high density reel, filaments, synthetic fibers Cheese yarn, cone dyed yarn density and surface hardness testing of soft materials. This instrument has a simple, intuitive readings, easy to carry, versatile and so on.
Hardness test principle is based on a known spring under pressure "pressure needle end pressure: 0.55N-8.06N (56g-822g)", the probe piercing the surface of the object to be measured by the resistance, piercing the degree of conversion pointer dial into hardmeter reading.
B. specification
DP-XF-O spindles hardmeter can be divided into: O type, OO type two kinds. FIG. 1 "O type":
C. Technical Specifications
1. Measuring range: 0 ~ 100Hw; Accuracy: 1
2. Spherical Column Diameter: 3mm
3. Pressure needle stroke: 0 ~ 2.5mm
D. Instruction manual
The sample is placed on the platform, hold hardmeter, indenter distance Cheese yarn edge at least 15mm, so that the vertical pressure needle pressed into the surface of the yarn sample Cheese, until the internal pressure readings 1s and spindles foot specimen in full contact. In measuring point distance of at least 20mm measured at different locations more than 5 times the mean value.
For accurate data, to improve detection accuracy, reduce human factors that can be hardmeter mounted on the carriage, and spindles supporting height. Detection precision and accuracy greatly improved.
