One of them is the AWS, our all-welded diaphragm seal gauge that eliminates potential leak points and other issues associated with loosened connections.<\/strong><\/p>\n<p style=\"font-weight: 400\">The process industry relies on\u00a0<a href=\"https:\/\/www.wika.com\/en-us\/diaphragm_seals.WIKA\" rel=\"external\" target=\"_blank\">diaphragm seals<\/a>\u00a0to protect sensitive pressure instruments,\u00a0<a href=\"https:\/\/blog.wika.com\/us\/\/products\/pressure-products\/diaphragm-seals-ultimate-protection-for-safer-more-sanitary-pressure-measurement\/\">keep media uncontaminated<\/a>, and make system monitoring more reliable. Yet some challenges remain:<\/p>\n<ul>\n<li>Vibration and pulsation that loosen fasteners<\/li>\n<li>Process media that corrode certain O-rings and gaskets<\/li>\n<li>Extreme temperatures that cause threads to pull away from each other<\/li>\n<\/ul>\n<p style=\"font-weight: 400\">Each of these process conditions results in a poor seal, which could mean inaccurate readings and fugitive emissions. <span>\u00a0\u00a0\u00a0<\/span><\/p>\n<p style=\"font-weight: 400\">Among WIKA\u2019s many innovative solutions for the process industry is the AWS. Here is how our all-welded seal gauge solves these challenges.<\/p>\n<h2>Challenge #1: Vibration and pulsation cause fasteners to eventually loosen<\/h2>\n<p style=\"font-weight: 400\"><em>Thermal cycling and many other process conditions produce vibration and pulsation, which means that clamping bolts and other fasteners sometimes work themselves loose.<\/em><\/p>\n<p style=\"font-weight: 400\"><strong>Solution:\u00a0<\/strong>A key feature of the All-Welded System is that the upper and lower housings of the diaphragm seal body are welded together. This eliminates the need for clamping and fasteners. The <a href=\"https:\/\/www.wika.com\/en-us\/232_34_233_34.WIKA?ProductGroup=85995&amp;294=1215\" rel=\"external\" target=\"_blank\">industrial process gauge<\/a>of this assembly is also permanently welded to the upper housing of the seal body, thereby eliminating leak paths.<\/p>\n<p style=\"font-weight: 400\">Even under heavy vibration and pulsation, the AWS maintains its seal integrity, making it the perfect design in these types of challenging applications.<\/p>\n<h2>Challenge #2: Sealing materials incompatible with the process media<\/h2>\n<p style=\"font-weight: 400\"><em>The O-rings and gaskets used in diaphragm seal bodies are often made of elastomers. However, elastomeric materials vary in their resistances against different process media.<\/em><\/p>\n<p style=\"font-weight: 400\"><strong>Solution:\u00a0<\/strong>WIKA\u2019s all-welded process seal gauge has a recessed design, with the diaphragm welded to the upper housing. Our innovation eliminates the need for O-rings and gaskets, thus removing the issue of elastomer incompatibility. This makes the AWS ideal for use with corrosive, contaminated, or viscous media.<\/p>\n<h2>Challenge #3: Poor thread contact between the gauge and seal body<\/h2>\n<p style=\"font-weight: 400\"><em>The diaphragm seal body attaches to the pressure gauge via a thread connection. This connection is usually tight, but in extreme temperatures, materials can expand or contract \u2013 and potentially release gases or system fill fluid into the environment.<\/em><\/p>\n<p style=\"font-weight: 400\"><strong>Solution:\u00a0<\/strong>The process gauge of an AWS is permanently welded to the upper housing of the diaphragm seal body. This eliminates the possibility of poor thread engagement.<\/p>\n<p style=\"font-weight: 400\">An additional benefit of our diaphragm seal assembly is that it is fully contained and tamper resistant. This qualifies the AWS as a dual-containment system, making it a leader in safety and environmental responsibility.<\/p>\n<h2>The AWS: Two innovative products welded into one<\/h2>\n<p style=\"font-weight: 400\">To create the All-Welded System, we took two of our highest-performance instruments and expertly welded them together into one exceptionally reliable solution.<\/p>\n\n      <div class=\"wp-caption alignright\" style=\"max-width:258px;\"><img decoding=\"async\" src=\"https:\/\/blog.wika.com\/us\/\/files\/2020\/09\/aws.png\" alt=\"Models M932.D1, M933.D1\" \/><p class=\"wp-caption-text\">All-Weld System (AWS)<\/p><\/div>\n    \n<p style=\"font-weight: 400\">The\u00a0<a href=\"https:\/\/www.wika.com\/en-us\/232_34_233_34.WIKA?ProductGroup=85995&amp;294=1215\" rel=\"external\" target=\"_blank\">23X.34 XSEL<sup>\u00ae<\/sup>\u00a0process gauge<\/a>\u00a0is expressly designed for demanding conditions in the process industry:<\/p>\n<ul style=\"font-weight: 400\">\n<li>Stainless steel movement and socket to withstand corrosive environments<\/li>\n<li>Fiberglass-reinforced thermoplastic (POCAN) case for excellent load-cycle stability and shock resistance<\/li>\n<li>Pressure measurement from vacuum to 10,000 psi (690 bar) in combination with an AWS<\/li>\n<li>Movement with a built-in 50% over-range protection with no loss of accuracy<\/li>\n<li>A choice of\u00a0<a href=\"https:\/\/blog.wika.com\/us\/\/knowhow\/reasons-to-choose-liquid-filled-industrial-pressure-gauge\/\">liquid case filling<\/a>\u00a0for applications with high dynamic pressure loads and vibrations, and to protect gauges from environmental ingress<\/li>\n<li>Standard equipped with a threaded restrictor to reduce the impact from pressure spikes and high dynamic pressure cycles<\/li>\n<li>Fully traceable assembly with order and material information engraved on the gauge<\/li>\n<li>Approval requirements and certificates (EU, Canada, CIS countries) upon request<\/li>\n<\/ul>\n<p style=\"font-weight: 400\">The bottom half of the assembly is the\u00a0<a href=\"https:\/\/www.wika.com\/en-us\/990_34.WIKA\" rel=\"external\" target=\"_blank\">model 990.34 diaphragm seal with welded design<\/a>.
