美***OMEGA歐米茄TFD平坦RTD元件/薄膜檢測器OMEGA歐米茄用于風(fēng)洞和空調?？焖夙憫獣r(shí)間，溫度范圍：-50至550'C（-60至1020'F）這種扁平鉑電阻探測器代表了歐米茄在微型化溫度傳感裝置方面的***新發(fā)展。它將鉑電阻探測器的精確溫度測量能力與熱電偶的小溫度傳感頭和快速響應時(shí)間相結合。表面溫度測量是熱釋光器件***直接的應用領(lǐng)域。由于TFD具有較大的表面積和體積比，并且溫度敏感的鉑層與被測量介質(zhì)分離，因此它的響應時(shí)間很快。

美國OMEGA歐米茄TFD平坦RTD元件/薄膜檢測器OMEGA歐米茄有關(guān)將歐米茄“TFD”系列RTD元件組裝到延長(cháng)線(xiàn)的說(shuō)明：這些RTD元件由涂有鉑的鎳導線(xiàn)制成。由于鉑不容易被大多數軟焊料弄濕，我們建議在需要時(shí)將其點(diǎn)焊或銀焊到延長(cháng)線(xiàn)上。

Used in Wind Tunnels and Air Conditioners.

Rapid Response Time

Temperature Range: -50 to 550°C (-60 to 1020°F)

This flat platinum resistance detector represents the latest development by OMEGA in miniaturization of temperature sensing devices. It combines the precision temperature measuring capability of the platinum resistance detector with the small temperature sensing tip and rapid response time of the thermocouple. An immediate field of application for the TFD is in the area of surface temperature measurement.. Rapid response times are achieved with the TFD because it possesses a large surface-area to- volume ratio and the temperature-sensitive platinum layer is separated from the medium to be measured by a thin ceramic substrate of high thermal conductivity. Note on Assembling Omega "TFD" Series RTD Elements to Extension Wires: These RTD elements are made with platinum coated nickel lead wires. Since platinum does not easily wet with most soft solders, we advise that they be spot welded or silver soldered to extension wires when required.
