TN11528 Automatic Pick Counter

INTRODUCTION

Measures the thread density ("pick count") of woven fabrics and wire meshes as well as the loop density of knitted fabrics.

SCOPE

The 3250 Automatic PICK COUNTER is used for fast, convenient and accurate determination of the thread density of woven fabrics and wire meshes as well as the loop density of knitted fabrics.

The instrument has a measuring range of 8 through 300/cm (20 through 762/in).

The instrument is equally suitable for measurements in the laboratory and mobile applications in the production environment. Since the instrument also works at moving

test specimens, measurements can be taken directly at the running production machine or loom.

Its handy size and its ability to determine even extremely high thread densities , make the instrument a static-of-the-art alternative to the traditional pick glass and interference template.

FUNCTION

For testing, the face of the instrument is placed onto the test specimen. After manually entering the search range in which the test result is expected to fall, the start button is pressed. By means of a high quality lens system a narrow line of the test specimen is projected onto a linear CCD array. The signal from the CCD array is processed by a micro processor, and after less than a second the average thread density of the test specimen is digitally displayed.

A special illumination system eliminates the interfering effects of colors and patterns. Therefore, even colored and patterned test specimens deliver a perfect test result.

Because of its small size and light weight design the instrument is perfectly suited for mobile use.

For stationary operation in the laboratory the instrument may be mounted to the optional FX 3250-MT Stand.

The instrument is equipped with a RS 232 data port.

The instrument can be calibrated and is supplied with an ISO conform calibration certificate. Also supplied is a calibration card for instantaneous verification of the proper function and calibration as well as for re-calibration of the instrument.

EVALUATION OF THE TEST RESULTS

1.The simplest method for evaluation of the test results is to read the test results from the digital display, to write them down and to evaluate them manually.

2.In order to eliminate all reading, writing and calculating tasks and related errors, the instrument can be connected to the Strip Printer L 5130 MINIPRINT, which documents the test results, including statistical analysis, on a 57 mm (2.25") wide strip of paper (see adjacent picture).

3.Alternatively, the PICK COUNTER can be connected to a PC or Laptop computer with the Evaluation Program L 5110 LABODATA III. The PC prints a comprehensive test report, including statistical analysis of the test results (see separate picture).

4.In addition, it stores the test results on the hard disk and performs long-term evaluations based on various selection criterions. Up to five different TEXTEST instruments can be connected to the PC at the same time. The test results from these instruments can be processed simultaneously and documented together on the same test report.

5.Thus, the Evaluation Program L 5110 LABODATA III turns the PC into a complete data processing system for the testing laboratory.
