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.
