Extreme process temperatures reduce the accuracy, reliability, durability and lifespan of a pressure gauge. The Sta-Kool cooling element was designed specifically with high-temperature processing environments in mind. Under laboratory test conditions, the 316L stainless-steel Sta-Kool cooling element was able to reduce 400°F liquid process temperatures to 100°F at the active portion of the Bourdon tube. The Sta-Kool has a maximum operating temperature of 750°F at 3,500 psi operating pressure, and a maximum operating pressure of 5,000 psi at 100°F. It can be either threaded or welded to any pressure gauge with ½-in. NPT male connection made from a compatible material. It can also be attached in between a pressure gauge and diaphragm seal for the most comprehensive process measurement-protection possible, protecting the instrument from both pulsation and temperature extremes. — Ametek US Gauge, Largo, Fla.
