Watlow熱電偶 MICROCOIL?熱電偶
在垂直表面測量中的準確，可重復(fù)和快速響應(yīng)
瓦特隆的MICROCOIL?微型熱電偶提供表面溫度測量，可提供的度。這項技術(shù)可實現(xiàn)關(guān)鍵的等溫表面溫度測量，并提供的設(shè)計靈活性。
使用MICROCOIL可以實現(xiàn)1％到2％（DT）的典型傳感器到傳感器重復(fù)性，因為易受正常生產(chǎn)差異影響的傳感器區(qū)域不在熱梯度范圍內(nèi)。焊接位置，絕緣厚度和焊接厚度不再影響等溫環(huán)境中的測量。因此，測量表面溫度的固有挑戰(zhàn)不再存在。
MICROCOIL熱電偶采用瓦特隆的XACTPAK???礦物絕緣熱電偶電纜。當(dāng)與未接地的接頭一起使用時，傳感器與被測表面電隔離。對于更高電壓的應(yīng)用，氮化鋁傳感器盤選項可用于額外保護。
MICROCOIL熱電偶的螺旋設(shè)計可以提高響應(yīng)時間，因為表面溫度只能通過電纜的直徑和傳感器盤的寬度傳導(dǎo)。
熱分析證明了MICROCOIL技術(shù)的性能。這種工藝可以在很長的非常小的電纜上實現(xiàn)關(guān)鍵的等溫區(qū)域，確保準確和可重復(fù)的測量。
標準直傳感器的響應(yīng)時間準確性差，不可重復(fù)的結(jié)果以及20％到30％甚至更高的誤差。

MICROCOIL™ THERMOCOUPLES

ACCURATE, REPEATABLE, & FAST RESPONSE IN PERPENDICULAR SURFACE MEASUREMENT

Watlow’s MICROCOIL™ miniature thermocouple provides surface temperature measurements that deliver an unparalleled degree of accuracy. This patented technology achieves critical isothermal surface temperature measurement and offers superior design flexibility. 

Typical sensor-to-sensor repeatability of one to two percent (DT) can be achieved with the MICROCOIL because sensor areas that are vulnerable to normal production variances are not inside of the thermal gradient. Weld location, insulation thickness and welded tip thickness no longer impact measurement in an isothermal environment. Therefore, the inherent challenges of measuring surface temperatures no longer exist.

The MICROCOIL thermocouple utilizes Watlow’s XACTPAK® mineral insulated thermocouple cable. When used with an ungrounded junction, the sensor is electrically isolated from the surface being measured. For higher voltage applications, the aluminum nitride sensor disc option can be used for additional protection.

The helix design of the MICROCOIL thermocouple elicits a faster response time because the surface temperature conducts only through the diameter of the cable and the width of the sensor disk. 

Thermal analysis demonstrates the superior performance of the MICROCOIL technology. This patented process achieves critical isothermal area for a long length of a very small cable, ensuring accurate and repeatable measurement.

Standard straight sensors experience poor accuracy of response time, non-repeatable results as well as errors ranging from 20 to 30 percent and higher.
