חיבור תהליך אוגני, אטמי דיאפרגמה
תיאור
אטמי דיאפרגמה משמשים להגנה על מכשירי מדידת לחץ ביישומים תובעניים בתנאים קשים. מערכות אטם דיאפרגמה אלה, הכוללות משדר לתהליך, חיישן לחץ, מד לחץ או מתג לחץ עם אטם דיאפרגמה, ניתנות לשילוב באופן פרטני עבור כל יישום של הלקוח. לשם כך זמינים מגוון רחב של תצורות שונות, חיבורי תהליך, סוגי התקנה וחומרי מגע.
דגמי אטם דיאפרגמה עם חיבורי אוגן זמינים עם דיאפרגמות צמודות (flush) או פנימיות, בתכנון צינורי או כאטמי דיאפרגמה בטור (in-line).

שאלות ותשובות
מה מודדים באמצעות ה-990.28?
ה-990.28 הוא אטם דיאפרגמה, כלומר רכיב הפרדה במערכת אטם דיאפרגמה המחובר למשדר לחץ, חיישן לחץ, מד לחץ או מתג לחץ. הוא מעביר את הלחץ מהמדיום אל מכשיר המדידה תוך הפרדה מלאה ביניהם.
לאילו מדיה מתאים האטם?
האטם מיועד למדיה אגרסיבית, בעלת צמיגות גבוהה, מתגבשת או חמה. מגוון חומרי המגע — מ-Hastelloy C276 (2.4819) ו-Tantalum ועד PFA ו-Wikaramic® — מאפשר התאמה למדיום הספציפי.
אילו חיבורי תהליך ורוחבים נומינליים זמינים?
האטם זמין לפי התקנים DIN EN 1092-1, ASME B16.5-2017, GOST 33259 ו-JIS B2220, ברוחבים DN 40 עד DN 125 וכן 1 ½" עד 5", ובנוסף בגרסאות DN 40A עד DN 100A.
מה מבדיל את ה-990.28 מאטמי דיאפרגמה אחרים?
זהו אטם תאי (cell-type) קומפקטי עם אוגן ביניים ודיאפרגמה צמודה (flush), המתאים במיוחד למדיה צמיגה או מתגבשת שבה דיאפרגמה צמודה מונעת הצטברות באזור המדידה.
אילו תעודות זמינות לדגם?
הדגם זמין עם תעודות NACE MR0175 / ISO 15156 ו-NACE MR0103 / ISO 17945, וכן תעודות בדיקה EN 10204 2.2 ו-EN 10204 3.1.
האם הדגם מתאים ליישומים עם דרישת SIL?
כן, הדגם נתמך ברמת שלמות בטיחות (SIL).
