Description
Extreme process temperature reduces the accuracy, reliability, durability, and the overall life of a pressure gauge. The AMETEK U.S. Gauge (USG) Sta-Kool鈩 cooling element was designed for pressure measurements with this extremely high temperature environment in mind. Under actual laboratory testing condition, in still room air, the 316L stainless steel Sta-Kool鈩 cooling element was able to reduce 400掳F (204掳C) liquid process temperature
down to 100掳F (38掳C) at the active portion of the Bourdon tube (see chart 1 on next page).
AMETEK USG recommends using a Sta-Kool鈩, capillary or diaphragm seal to protect pressure gauges, pressure transmitters or pressure switches (not supplied by USG) from process temperatures exceeding 190潞F. Anything exceeding 190潞F will start to degrade weld joints and electronics. The Sta-Kool鈩 can be either threaded or welded (to eliminate a potential leak path) to any pressure gauge with 1/2" NPT male connection made out of
compatible material.
Furthermore, the Sta-Kool鈩 cooling element can be attached in between a pressure gauge and diaphragm seal for the most comprehensive process measurement
