Installation Manual Supplementary information 20002346 October 2020 Supplementary information Purge the sensor case Prerequisites Make sure the following are available before beginning the purge procedure: ™ • Teflon tape • Argon or nitrogen gas sufficient to purge the sensor case Whenever a purge plug is removed from the sensor case, you must purge the case again. -
Page 22: Pressure Relief
Supplementary information Installation Manual October 2020 20002346 • If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so that the purge gas will displace air from bottom to top. • If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so that the purge gas will displace air from top to bottom. - Page 23 Installation Manual Supplementary information 20002346 October 2020 WARNING • Orient the sensor so that personnel and equipment will not be exposed to any discharge along the pressure relief path. • Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor can cause severe injury or death.
