AMETEK’s All-welded Gauge and Seal offers customers a lower cost alternative
to an individual gauge and diaphragm seal with the added benefit of a
reduction in potential leaks. Our high quality, rugged SOLFRUNT®1981 (SST
internals) gauge is mounted and welded onto our M&G Diaphragm Seal.
AMETEK’s line of high quality process gauges are specifically designed to
meet the demanding needs of the chemical and petroleum processing
industries, and are also widely used in industries such as fossil fuel and
nuclear power generation, aerospace and marine. The gauge’s design and
materials of construction provide reliable service in applications where
corrosive atmospheres, corrosive media, pressure pulsation, vibration, and
wide variations in ambient temperatures are present.
Ametek gauge cases feature an integral wall between the measuring element
and the window, and a pressure relieving back for increased safety1. They
are available in various styles, case materials, and mounting arrangements,
and wetted parts are available in bronze, stainless steel, alloy steel, and
MONEL®. Recalibration adjustments can be made from the rear of the case
without removing the internals. On the 1900 Series the pointer is adjusted
by removing the ring and front window. |
