תיאור
בכל מקום שבו יש צורך להציג את טמפרטורת התהליך באתר או במקומות שקשה לגשת אליהם, ובו בזמן נדרשת החלפה של מעגלים, מדחום המופעל באמצעות גז עם מגעי מתג מתאים לשימוש.
בשל מגוון רחב של אפשרויות תכנון, ניתן להתאים בצורה מושלמת את מדי הטמפרטורה המופעלים באמצעות גז מדגם TGS73 לכל חיבור לתהליך או לכל מיקום. בגרסת הגבעול והחוגה הניתנים לכוונון, ניתן לכוון במדויק את הגוף לזווית הצפייה הרצויה.
בגרסת נורת מגע (ללא מגע ישיר עם המדיום), ניתן למדוד ולהפעיל מיתוג גם כאשר קוטר הצינור קטן מאוד. נורת המגע מיועדת להרכבה חיצונית על צינורות ועל מכלים. בעת התקנת גרסת מדחום זו, יש לוודא שנורת המגע נמצאת במגע עם נקודת המדידה לכל אורך הנורה.

איור תחתון: הרכבה אחורית
מגעי מתג (מגעי אזעקה חשמליים) יוצרים או מנתקים מעגלים בהתאם למיקום המחוג של מכשיר המדידה המציין. מגעי המתג ניתנים לכוונון על פני כל טווח המדידה. מחוג המכשיר (מחוג הערך בפועל) נע בחופשיות על פני כל טווח הסקאלה, ללא תלות בכיוון הכוונון. ניתן לכוון את המחוג המוגדר באמצעות החלון באמצעות מפתח כוונון נשלף (מותקן על שקע הכבל). ניתן גם להגדיר מגעי מתג המורכבים ממספר מגעים כך שיפעלו לנקודת הגדרה אחת. הפעלת המגע מתבצעת כאשר מחוג הערך בפועל נע מעבר לנקודת ההגדרה הרצויה או מתחתיה.
כמגעי מתג זמינים: מגעי הצמדה מגנטיים (snap-action), מגעים אינדוקטיביים ומגעים אלקטרוניים. ניתן להשתמש במגעים אינדוקטיביים באזורים מסוכנים. לצורך הפעלה של בקרי לוגיקה ניתנים לתכנות (PLC) ניתן להשתמש במגעים אלקטרוניים.

שאלות ותשובות
מהו טווח המדידה של המדחום?
קיים מגוון רחב של טווחים, מ־-80 … 60 °C ועד 0 … 700 °C; הטווח המדויק נבחר לפי הדגם הספציפי.
מהי דרגת הדיוק?
Class 1 לפי DIN 16196 בטמפרטורה סביבתית של 23 °C ±10 °C.
אילו חיבורי תהליך זמינים?
M18 x 1.5, M20x1.5, M24 x 1.5, G ½ B, G ¾ B, ½ NPT ו־¾ NPT.
מהם סוגי המגעים הזמינים?
מגעי הצמדה מגנטיים (snap-action), מגעים אינדוקטיביים ומגעים אלקטרוניים; המגעים ניתנים לכוונון על פני כל טווח המדידה.
האם ניתן להשתמש במדחום באזורים מסוכנים (Ex)?
כן — גרסאות עם מגעים אינדוקטיביים מיועדות לשימוש באזורים מסוכנים ומאושרות לפי ATEX ו־IECEx.
מהי דרגת ההגנה מפני חדירה?
IP65.
מה מבדיל את ה־TGS73 מדגמים סמוכים?
הוא משלב תצוגה מקומית עם מיתוג חשמלי בגרסת נירוסטה, ומאפשר מדידה ללא מגע עם המדיום באמצעות נורת מגע המורכבת חיצונית על צינורות ומכלים — גם כאשר קוטר הצינור קטן מאוד.
מהו חומר הנורה והמידות שלה?
הנורה עשויה נירוסטה 316, באורך 200 mm ובקוטר 6.0 mm.

| Thermowell / Protection tube | In principle, the operation of a mechanical thermometer is possible without a thermowell / protection tube with low process-side loading (low pressure, low viscosity and low flow rates). However, in order to enable exchanging the thermometer during operation (e.g. instrument replacement or calibration) and to ensure a better protection of the measuring instrument and also the plant and the environment, it is advisable to use a thermowell / protection tube from the extensiveWIKA portfolio. → For further information on the wake frequency calculation of the thermowell / |
