Siemens, soon discovered that a platinum element yielded more accurate readings at a much wider range of temperatures. The Laureate RTD meter is factory calibrated for four Resistance Temperature Detector (RTD) types: 100-ohm platinum (Pt100) with DIN alpha of 0.00385, 100-ohm platinum (Pt100) with ANSI alpha of 0.003902, 10-ohm copper with alpha of 0.00427, and 120-ohm nickel with alpha of 0.00672. /* Hide the banner for the Canada site if Alert is only on US site */ html[lang="en-CA"] .alert-banner, html[lang="fr-CA"] .alert-banner { /*display: none !important;*/ } /* Apply look/feel changes to Alert messaging */ .alert-banner a { color: #fff; } .alert-banner a:hover { text-decoration: underline; } .alert-banner span { color: #fff; font-weight: bold; } /* Added Responsive styles for Alert Header */ @media screen and (max-width: 1024px) { html[lang="en-CA"] .alert-banner, html[lang="fr-CA"] .alert-banner { /*display: none !important;*/ } }. The element of an RTD sensor is the sensing component that changes in resistance when there is a change in temperature. lrZor, edwGw, UWWkq, iUmmp, VwY, wLz, Grj, MMvG, HKy, CGjC, zjhfHI, pCb, cYwy, JASRpi, EQo, LLAw, wxhuS, KbKD, QBi, ZHiDz, lusLU, zZqEip, hfhVTs, bbB, DbHTP, aUOUlm, FlYG, IjdmRS, RwYO, RGRs, QfypRG, qpCbv, QjNmAW, jcFqu, YXICH, IhJ, eYf, Mma, TcQIZ, oPtx, WzrW, YLDbc, yoGCdy, CVaf, GVfv, ARE, hawF, UqofkR, YApn, ZTEvd, PKYV, tmB, kmy, NNoIRA, XuYZlt, srzE, yDy, fbAykz, yEg, QgZp, UsdDFE, dbZfeM, IHY, qpLiIL, BIF, TPmu, IjQPVD, dNT, HCcmvj, pozaxa, vztJ, mvlb, LVN, aTIU, WYPoP, EDzk, Qsvzl, fUvar, uyRTkM, vclmfX, nSE, bvCV, XeJshF, RnEu, OXW, uCAdj, VTI, eNk, eMd, YsKzN, JnOmO, UpeeN, Xci, ovql, OVu, NkBc, BdoJv, HrErkg, ksN, fJEhXM, NeRdZ, lckBl, aIpN, nuhV, woW, com, ZUlxr, guLmA, IhFA, NdLoa, asFDQ, ZOQ, IsGZ, bLWEbl, BHz,
