Gauges and instruments equipped with diaphragm seals are essential in ensuring the safety of what we eat. Diaphragm seals play a critical role in industries that require high levels of sanitation, including the pharmaceutical, beverage, and water purification industries, to name just a few.<\/strong><\/p>\n

Producers of consumer items from these industries must strike a difficult balance: ensuring optimal product safety while keeping the product moving off the line. WIKA gauges equipped with diaphragm seals enable sanitation-conscious producers to achieve high levels of both safety and productivity. In sanitary or sterile facilities, a diaphragm seal protects the product from the chemicals and temperatures used to achieve the required level of cleanliness. Here, the diaphragm seal separates the measuring instrument from the process medium using a thin, flexible metal diaphragm. The diaphragm seal is welded flush to a housing that complies with the preferred sanitary process connection. A diaphragm seal assembly consists of a pressure gauge mounted to a diaphragm seal and a transmission \u2014 or system fill \u2014 fluid. This fluid transmits the process pressure hydraulically from the diaphragm to the measuring instrument, allowing accurate and repeatable measurement while preventing system fill fluid from coming in contact with the item being processed. The diaphragm seal can be attached to the gauge in any of three basic configurations:<\/p>\n
