Eltex UPG16720/16730 Stitch16750 16760斷紗檢測器縫紉線檢測器

 概述

    UPG斷紗檢測器小巧通用，利用壓電原理檢測紗線的運動。它工作原理使適用于所有類型的紗線，而不敏感于灰塵。

     檢測器光耦開關信號輸出，可以PLC和其它電氣控制設備相連接。

     有LED指示紗線的活動狀態。

功能特性

傳感部件                    氧化鋁陶瓷眼，孔徑?3 mm，寬7 mm

輸出                          光電開關，無紗運動為閉合狀態

靈敏度調節                   調節底部的電位器

當有紗線運動時，光電開關是開路的，當無紗運動時，為閉合狀態。

LED燈亮指示為有紗線運動。

檢測器的電纜連接有6/4水晶頭，可多個檢測器并聯，還帶反電壓保護。

Eltex UPG yarn break detector thread break detector 16720/16730 Stitch16750 16760

General description

The UPG is a small, general purpose, thread break detector. It operates on the piezoelectric principle, detecting the yarn movement. This working principle makes it suitable for all types of yarn and makes it insensitive to dust, dirt and humidity variations.

The detector has an opto－coupler output suitable for PLC or other electronic control devices.

A LED (light emitting diode) indicates the yarn movement.

The ceramic sensor part can be used either as a closed eyelet or as an open bar. Several detectors can be connected in parallel.

Function description

Sensing part                     Aluminium oxide ceramic, with a ?3 mm closed eyelet and a 7 mm wide bar.

Output                              Opto－coupler, active when yarn isnot moving.

Sensitivity setting           The sensitivity can be adjusted with a potentiometer under the lid.

The output reflects the movement of the yarn. When the yarn is moving, the optocoupler is inactive. When the yarn is not moving, the optocoupler is active.

The LED is on when the yarn is moving.

The detector is supplied with cable and a 6/4 modular plug connector. Many thread detectors can be connected in parallel. The detector is protected against wrong polarity on power supply.
