Hydrophilic Coating Guide Wire Friction Tester Layer guide wire" research and development
.
It is a test instrument developed for the performance index test of the frictional force of medical human internal and external catheters and guide wires
.
The equipment adopts imported sensors, high ball screw and structural design; it ensures high stability of operation
.
The test results and curves are stable, and the stepless speed regulation can meet the test speed requirements of non-standard experiments
.
The equipment is used in testing institutions and medical device manufacturers
.
1.
Overview The hydrophilic coating guide wire friction tester is suitable for testing the surface friction and sliding properties of disposable non-intravascular catheter guide wires such as urinary catheters, guide wires, balloon catheters, and tracheal intubation
.
Adopt 7-inch Weiluntong touch screen (man-machine integrated operation is convenient for 7-inch color brand Weiluntong humanized touch screen, the touch screen has high sensitivity and does not hurt the eyes)
.
2.
Working principle During the test, the tensile force is measured by a force sensor, and the tensile force is converted into a weak voltage signal, amplified by an amplifier, input to the A/D converter, converted into a digital quantity, sent to the PLC, and the strength of the force is displayed by the LCD display.
; The operator enters the operation signal into the PLC through the keyboard, controls the stepper motor to do the tensile test, measures the elongation at break and the strength, and the test report J record is saved in the man-machine interface and can be exported by the U disk
.
Third, the technical indicators 1.
Form: constant velocity elongation (CRE) 2.
Tensile speed: 0～200mm/min, no-load speed error does not exceed ±2% 3.
Force value measurement range: 0～20N, accuracy is ±0.
005% 4.
Elongation indication error is less than ±1mm5.
Pre-tensioning: manual tensioning, adjustable from 0 to 100N 6.
Chinese liquid crystal display (breaking strength, breaking elongation, breaking elongation, statistical data table, etc.
) 7.
Power supply voltage: AC220V±10%, power 350W8.
Dimensions (L×W×H): 780×360×1180mm9.
