2010年5月24日——通用电气的PRV泄漏检测系统使用Bently Nevada Trendmaster Pro架构来收集定期的在线温度和声学测量值，并在系统1软件中自动分析它们。通过以互补的方式使用温度和声学测量，可以获得比单独使用任一技术时更可靠的检测。然后，这些测量值通过系统1软件的决策支持引擎中的特殊规则库进行处理。该规则库包含PRV泄漏行为的复杂、嵌入式知识，可自动检测泄漏的存在。泄压阀(PRV)广泛用于炼油厂、化工厂、管道、发电厂和其他工业应用中，作为泄压系统的一部分，以保护管道、锅炉、容器和其他受压资产免受危险过压状况的影响。为了帮助用户确保这些系统的供应符合公认的良好工程实践，存在许多特定于行业的标准。例如，美国石油协会标准API 521(ISO 23251)、API 526和RP 520都专门针对石油工业中使用的压力泄放阀和泄压系统。压力泄放阀特别容易泄漏，这种泄漏的后果可能很严重:
危险的操作条件，增加工厂和人员的风险
对环境的破坏
监管罚款/处罚
负面公众形象/声誉
流程效率和盈利能力降低
原材料、中间产品或成品材料的损失尽管大多数公司通常以常规检查或观察的形式花费大量资源来检测和缓解泄漏，但目前的方法并未被证明完全有效，PRV泄漏仍然是行业面临的重大挑战。此外，压力泄放阀经常受到不必要的维护。这种情况发生在泄漏无法确认的时候，但是为了谨慎起见，预防性维修、更换或检修是“以防万一”进行的。这会导致压力泄放阀的相对维护成本非常高。现在可以利用经济、可靠的在线技术来监控关键压力泄放阀是否存在泄漏。在线方法意味着泄漏在几分钟内被发现，事故严重性(和相关后果)被最小化，并且消除了昂贵的例行检查制度。
