שאלות ותשובות

מהו טווח המדידה של ה-LF-1?

החיישן זמין בטווחי מפלס מ-0 … 0.1 mH2O ועד 0 … 60 mH2O.

מהו הדיוק של החיישן?

הדיוק הוא ≤ ±0.5 % of span (option).

האם החיישן מתאים לאזורים עם סיכון פיצוץ?

כן. ה-LF-1 מאושר ל-ATEX ו-IECEx עבור Zone 0 gas [II 1G Ex ia IIC T4/T5/T6 Ga] ו-Zone 1 gas [II 2G Ex ia IIC T4/T5/T6 Gb], וכן ל-CSA ו-FM עבור Class I, division 1, groups A, B, C, D.

מהו דירוג ההגנה מפני חדירה?

החיישן מדורג IP68, מה שהופך אותו מתאים להשקעה ממושכת בנוזל.

אילו אותות פלט זמינים?

זמינים 4 ... 20 mA (2-wire), 4 ... 20 mA + HART (2-wire), DC 0.1 ... 2.5 V (3-wire, low power), 2 x 4 ... 20 mA (2 x 2-wire, galvanically isolated) ו-2 x DC 0.1 ... 2.5 V (3-wire, low power). אספקת החשמל היא DC 8 ... 36 V, בהתאם לפלט ולאישור ה-Ex.

מאילו חומרים עשויים החלקים במגע עם המדיה?

החלקים במגע עם המדיה עשויים 316L, 318LN, Hastelloy C276, PUR, FEP, FKM או PVDF, בהתאם לדגם — מה שמאפשר שימוש במדיה אגרסיבית.

מה מבדיל את ה-LF-1 מדגמים אחרים למדידת מפלס?

ה-LF-1 מיועד במיוחד למדיה מזוהמת ואגרסיבית: פתח לחץ רחב והתנהגות ניקוז אופטימלית מונעים סתימה, והוא פותח עבור יישומים אלחוטיים ומערכות המופעלות על ידי סוללה. ---

Description	Order number
Additional weight The additional weight increases the dead weight of the submersible pressure sensor. It simplifies the lowering in monitoring wells, narrow shafts and deep wells. It effectively reduces negative environmental influences of the measuring medium (e.g. turbulent flows) on the measuring result. Stainless steel 316L, approx. 300 g [0.661 lbs], length 115 mm[4.53 in]	14131008
Cable strain relief clamp The cable strain relief clamp ensures easy and secure mechanical fastening of the submersible pressure sensor's cable. It serves to guide the cable to prevent mechanical damage and to reduce the action of tensile stresses.	14052336
Cable box The cable socket, with IP67 ingress protection and waterproof ventilati- on element, provides a moisture-free electrical termination for the sub- mersible pressure sensor. It should be mounted in a dry environment, outside any shafts or vessels, or directly in the switch cabinet.	14052339
Not suitable for hazardous areas! Intrinsically safe repeater power supply, model IS Barrier Input 0/4 ...20 mA, supplying and non-supplying Bidirectional HART ® signal transmission For details see data sheet AC 80.14	14117118
Indication and programming module HART ® DIH50 and DIH52 5-digit display, 20-segment bar graph, without separate power supply, with additional HART ® functionality. Automatic adjustment of measuring range and span. 'Secondary-master' functionality: Setting the measuring range and unit of the connected transmitter using HART ® standard commands possib- le. Optionally explosion protection per ATEX.	on request
HART ® modem with USB, RS-232 or Bluetooth  interface For scaling the measuring range using a PC via the HART protocol, a HART modem with USB, RS-232 or Bluetooth interface is available. The modem communicates with all registered HART field instruments and can be used with the most popular HART-compatible software programs.	7957522 (RS-232 interface) 11025166 (USB interface) 11364254 (Bluetooth  interface)
