## תיאור

מכשירי מדידת צפיפות הגז של WIKA מספקים התרעות אמינות מפני רמות גז נמוכות באופן מסוכן, גם בתנאי סביבה קיצוניים. חשמלי ...

## יישומים

- Medium and high-voltage equipment
- Gas density monitoring of closed SF 6 gas tanks
- Raising an alarm when defined limit values have been reached

## תכונות מיוחדות

- Local indication with switch contacts
- Temperature-compensated and hermetically sealed, therefore no influence of temperature fluctuations, height differences and atmospheric pressure fluctuations
- Compensation possible for gas mixtures
- Functional check or calibration possible without dismounting, in accordance with EU regulation no. 517/2014 on fluorinated greenhouse gases
- Test connection is welded to prevent leakage
