In this paper, a mathematic model of high speed rotational arc sensing is analyzed. Simulations have been implemented in two conditions, namely considering or without considering weld bead profile. The simulation results are consistent with the experimental results. The current waveforms at the beginning of the welding are different from those at middle of the welding because of the formation of the weld bead profile. The signal patterns for seam tracking and end-point detection are proposed. A phase shift between the rotation and the current variation is also discovered in the experiments. The mathematical model can be helpful for the interpretation and improvement of arc sensing systems","PeriodicalId":214056,"journal":{"name":"2005 Sensors for Industry Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130208199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike earlier standards like ANSI/ISA S84 and API 14 C, IEC 61511 facilitates mandatory performance based analysis of safety-instrumented functions based on failure data. It is observed that failure data of shutdown valves have been extremely high compared to other elements of safety-instrumented loop. Increasing number of valves in a loop also will drastically affect availability; maintainability, space and cost. Objective of this paper is to improve safe availability of shutdown valve by employing complete stroking instead of partial stroking, increasing diagnostic coverage by using continuous position monitoring instead of limit switches, eliminating the air regulator and selection of proper communication protocol. Some buffering capacity in process is also suggested to facilitate full stroking instead of partial stroking. It is envisaged that SIL 3 level with single shutdown valve in a safety instrumented loop can be achieved with these modifications","PeriodicalId":214056,"journal":{"name":"2005 Sensors for Industry Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132735521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Persistent dynamic routing (PDR) is a breakthrough set of techniques that address all of these requirements to support production-grade wireless sensor network implementations. Much of the technology development in the wireless sensor networking field comes out of the traditional static networking industry (i.e. DSDV, DSR, AODV) that is based on a relatively static environment and stable links. As a result, these developments are challenged to address all of the above-named requirements to the level required for production purposes. By contrast, the research on persistent dynamic routing comes out of the sensor research field that presumes an unstable, rapidly changing environment. The relationship among robustness, scalability and responsiveness will be discussed, and the concept of PDR is presented. In addition, the concept of high-capacity wireless sensor network (HC-WSN) is introduced and its benefits are discussed","PeriodicalId":214056,"journal":{"name":"2005 Sensors for Industry Conference","volume":"42 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120835813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
