Evenness tester for Testing & Quality Control Department

Evenness tester for Testing & Quality Control Department of a Textile Engineering College - Evenness tester is designed to measure with high accuracy the mass evenness and imperfections of the yarn. - Stands up for the high quality capacitive sensor which is suitable to test yarns, roving and slivers without need of another external sensor. - Capacitance Based, Suitable for 4 Tex to 40 K Tex spun yarn. - Testing times: Freely setting between 0.5min –50min. Measuring Specification: - Range of Material: Nm 250 (yarn) to 80g/m (sliver) - Dynamic measuring Range: 100%, ±50%, ±25%, ±12,5% - Testing times: Freely setting between 0.5min –50min. - Significant CV% and U%: 0.20% to 99.99% IPI (imperfections): - Number of channels: 4 channels - Thin place: - 60%, - 50%, - 40%, - 30% - Thick place: +100%, +70%, +50%, +35% - Nep: +400%, +280%, +200%, +140% Spectrograph: - Number of channels: max.160 channels Wave lengths analyzed: - cm to 1225.9 m at 400m/min and 6 mins - 1 cm to 613.0m at 200m/min and 6 mins. - Measuring mode: normal and half inert mode or normal and inert mode - Material speed: 8 – 25 – 50 – 100 – 200 – 400 m/min - Evaluating time: 10” to 19’ 50” at every increment of 10” Results of each individual test: - CV% coefficient of mass variation - U% mean deviation of mass variation - AVE relative yarn count - IPI with 4 channels for nep, thick place, thin place - DR% with 4 channels - CV(L)% with 4 reference lengths - Statistics and other results: - Mean, Range - Standard deviation (s) - CVB% - 95% confidence limits (Q95%) - IPI per 1000m (1 km) of yarn length - DRT%, CV(L)T% - Overall spectrogram - Data and graphics saved in MT5 databank, printable - and exportable to MS excel format - Deviation rate DR% - Number of channels: 4 channels - Reference length: 0.01 to 10 m - Level: ±0.01% to ±99.99% - CV(L)% - Number of channels: 4 channels - Reference length: 0.01 to 10 m Power supply: - Voltage: 110-240 Vac - Frequency: 50/60 Hz Air Supply: - Measuring frame: 0.2 Mpa and about 4m3/h - Test time: 6 seconds to 20 minutes, variable. - With all operational and optional accessories. - Origin: E.U
