PR-12-2-100-1/4-18-E-RP-SL_PR-12-2-100-1/4-24-E-RP-SL鉑RTD探頭OMEGA

更換RTD探頭有兩種配置，固定長(zhǎng)度用于直接浸入或彈簧加載用于熱電偶套管（允許與熱電偶套管底部良好接觸）。每個(gè)探頭均采用26 AWG多股鍍鎳銅，PFA絕緣電線（2根黑色，1根紅色）6“長(zhǎng)標(biāo)準(zhǔn)。

這些探頭組件可以用作我們的PR-12、-14和-18 RTD傳感器組件的替換傳感器，可以按原樣使用，也可以與我們的可選熱電偶套管和連接頭組合，以設(shè)計(jì)您自己的傳感器配置。

定長(zhǎng)探頭：

訂購(gòu)定長(zhǎng)替換探針時(shí)，探針的長(zhǎng)度規(guī)定為從探針尖端到1/2NPT螺紋的完全接合點(diǎn)（如圖所示，通常為1/2”）。注：如果在熱電偶套管中使用，建議使用彈簧式探頭。否則，必須考慮螺紋嚙合，以確保傳感器在安裝過(guò)程中不會(huì)因接觸熱電偶套管孔底部而損壞。

定長(zhǎng)探頭

彈簧探針：

訂購(gòu)彈簧式替換探針時(shí)，探針的長(zhǎng)度應(yīng)指定為其將放置的熱電偶套管的浸入長(zhǎng)度。浸入長(zhǎng)度是從熱電偶套管頂部到孔底部的距離。

彈簧加載探頭用于確保探頭底部位于熱電偶套管中，并存在少量力，以確保在暴露于工藝條件下時(shí)保持接觸。插入前傳感器的實(shí)際探針長(zhǎng)度比下面所示的浸入長(zhǎng)度稍長(zhǎng)，以便在傳感器插入熱電偶套管時(shí)，允許1/4”的彈簧壓縮。

Connection Heads and Thermowells Also Available.

Replacement RTD probes are available in two configurations, fixed length for direct immersion or spring loaded for use in thermowells (allows for good contact with the bottom of the thermowell). Each probe features #26 AWG stranded nickel plated copper, PFA insulated wires (2 black, 1 red) 6" long standard.

These probe assemblies can be used as replacement sensors for our PR-12, -14 and -18 RTD sensor assemblies, used as is, or combined with our optional thermowells and connection heads to design your own sensor configuration.

Fixed Length Probes:

When ordering fixed length replacement probes, the length of the probe is specified from the tip of the probe to the full engagement point of the 1/2NPT thread (which is typically 1/2" as shown). Note: If being used in a thermowell, typically spring loaded probes are recommended. Otherwise, the thread engagement must be taken into account to insure that the sensor is not damaged by contacting the bottom of the thermowell bore during installation. 

Fixed Length Probes

Spring Loaded Probes:

When ordering spring loaded replacement probes, the length of the probe should be specified as the immersion length of the thermowell it will be placed into. The immersion length is the distance from the top of the thermowell to the bottom of the bore.

Spring Loaded probes are used to insure that the probe bottoms in the thermowell, and that a small amount of force is present to insure that this contact is maintained when exposed to process conditions. The actual probe length of the sensor before insertion is a little longer than the immersion length as shown below to allow for a 1/4" spring compression when the sensor is threaded into the thermowell.
