KES - SE Friction Sensation Tester

### Introduction The KES - SE Friction Sensation Tester is a more versatile upgraded version of the KES - FB4 - A tester. It analyzes and mechanizes the hand movements of "stroking" by craftsmen and professionals when evaluating the style and hand - feel of fabrics, and converts the results into objective numerical data. It can obtain data on the friction coefficient, the variation of the friction coefficient, and surface roughness, which are used to objectively evaluate and quantify the "smoothness", "slip - ability", and "roughness" when touching. It is also suitable for measuring tactile - soft strips or hairs. ### Features - Quickly test the friction sensation and simulate the sensory signals when hands make contact. - Precisely analyze and express the sensations when touching objects. - Calculate the slipperiness during contact through the variation of the friction coefficient. - Related to the friction sensation of finger - touch: the larger the MIU value, the less likely it is to slide when touching; the larger the MMD value, the rougher the surface of the object. ### Specifications - **Dimensions/Weight**    - Device main body: W320×D200×H390(mm)/10kg    - Electronic amplifier device: W180×D400×H400(mm)/12kg - **Power Supply**: AC100V, maximum power consumption 30W - **Measurement Environment**: Temperature and humidity of 20～30°C/50～70%RH, without condensation. The standard temperature and humidity are 20°C/65%RH. Install in a place less affected by wind or vibration. - **Friction Force Detection**    - When measuring alone: The detector is a differential transformer (ring - type dynamometer). The full - scale load is 200gf (for standard measurement) and 1000gf (for low - sensitivity measurement), with an accuracy of less than ±0.5% of the full scale.    - When measuring simultaneously: The detector is of the resistance wire strain gauge type. The full - scale load is 200gf (for standard measurement, low - sensitivity measurement is not supported), with an accuracy of less than ±0.5% of the full scale. - **Surface Roughness Detection (when measuring simultaneously)**: The detector is a differential transformer, with a full - scale displacement of 0.4mm - Accuracy: less than ±1.0% of the full scale - Detector for measuring the movement amount of the detection surface: Potentiometer - Movement distance: 30mm (effective measurement distance range is 20mm) - Accuracy: less than ±0.5% of the full scale - Filter characteristics: Active secondary filter, μ = 0.6, ω0 = 1cps - Sensor dimensions    - Friction part: 10mm×10mm (when measuring alone)    - Roughness contact part: Use a 0.5mm wire, with a contact surface width of 5mm - Sample movement speed: 1mm/sec, 2mm/sec, 5mm/sec, 10mm/sec; 0.1mm/sec, 0.2mm/sec, 0.5mm/sec can be set using the change - over switch - Sample size: 30mm×270mm (standard)
