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

更换RTD探头有两种配置，固定长度用于直接浸入或弹簧加载用于热电偶套管（允许与热电偶套管底部良好接触）。每个探头均采用26 AWG多股镀镍铜，PFA绝缘电线（2根黑色，1根红色）6“长标准。

这些探头组件可以用作我们的PR-12、-14和-18 RTD传感器组件的替换传感器，可以按原样使用，也可以与我们的可选热电偶套管和连接头组合，以设计您自己的传感器配置。

定长探头：

订购定长替换探针时，探针的长度规定为从探针尖端到1/2NPT螺纹的完全接合点（如图所示，通常为1/2”）。注：如果在热电偶套管中使用，建议使用弹簧式探头。否则，必须考虑螺纹啮合，以确保传感器在安装过程中不会因接触热电偶套管孔底部而损坏。

弹簧探针：

订购弹簧式替换探针时，探针的长度应指定为其将放置的热电偶套管的浸入长度。浸入长度是从热电偶套管顶部到孔底部的距离。

弹簧加载探头用于确保探头底部位于热电偶套管中，并存在少量力，以确保在暴露于工艺条件下时保持接触。插入前传感器的实际探针长度比下面所示的浸入长度稍长，以便在传感器插入热电偶套管时，允许1/4”的弹簧压缩。

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.
