Thermocouples
A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end. When the junction of the two metals is heated or cooled a voltage is produced that can interpreted by a temperature controller, high limit or display device. There are two common constructions for these: Tube and Wire and Mineral Insulated. The tube and wire uses an empty stainless tube with a wire inside which has a welded tip incorporating the wire junction. This construction is typically used to 900?F. The Mineral Insulated construction uses a highly compacted stainless sheath with solid conductors encased in magnesium oxide insulation. This construction offers a wider variety of diameters, allows for the sensors to be bent in the field and for temperatures to 2200?F. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options.
热电偶
热电偶是测量温度的传感器。它由两种不同的金属组成, 一端连接在一起。当两个金属的连接被加热或冷却时, 产生的电压可以由温度控制器、高限制或显示装置解释。有两个共同的结构为这些: 管子和导线和矿物绝缘。管子和导线使用一个空的不锈钢管与导线里面有一个焊接的尖端包含导线连接。这种结构通常用于900?f. 矿物绝缘结构采用高度致密的不锈钢护套, 并将固体导体包裹在氧化镁绝缘中。这种结构提供了更广泛的直径, 允许传感器在现场弯曲和温度为2200?f. 这些传感器是一个巨大的一系列的物理封装与各种引线, 住房和安装选项
RTD’s Resistance Temperature Detectors
(RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. RTDs are also available in a Tube and Wire and Mineral Insulated construction. They are more accurate than thermocouples and are typically used for temperature sensitive and laboratory applications. We offer these in a variety of constructions and physical packages but are constrained by the size of the resistor beads. There are restrictions to the diameter and lengths of the available constructions
电阻温度探测器
(RTDs) 是温度传感器, 其中包含电阻值, 随着温度的变化而变化。RTDs 也可在管道、电线和矿物绝缘结构中使用。它们比热电偶更准确, 通常用于温度敏感和实验室应用。我们提供这些在各种结构和物理包, 但受到限制的大小的电阻珠。有对现有的结构的直径和长度的制约
