温度计接头的螺纹有公制与英制两种，其螺纹的选择应随温度计螺纹而定，两者必须相符。温度计螺纹有的是定型的，如双金属温度计，绝大多数情况是M27×2，安装双金属温度计的接头螺纹也必须是M27×2。温度计螺纹特别是电阻体与热电偶，它们随安装场合与温度而改变其螺纹大小。选择温度计接头时，一定要搞清楚温度计的螺纹。
温度计接头的长度取决于测温点是否要保温，不需保温的测温点，接头长度为60～80mm，需要保温的测温点，视保温层厚度决定，一般以露出保温层30～50mm为宜，接头长度一般为120～140mm，有时可达200mm。直型温度计接头使用广泛，设备上温度点都采用直型，管道上安装温度计视管道的直径，小直径(≥∅80mm)可用45°斜型，但必须是测温元件逆着流向。太小的管道直径(≤∅80mm)只能用扩大管来安装温度计。当管道≥∅200mm时，才能使用直型连接头。在条件许可时，安装在弯头上的温度计可减低对管道直径的要求。
There are two types of thread of thermometer connector: metric system and inch system.The selection of thread depends on the thread of thermometer, and the two must be consistent.Some thermometer threads are fixed,such as bimetallic thermometer, most of which are M27×2.The connector thread for installing bimetal thermometer must also be M27×2.Thermometer threads,especially resistance bodies and thermocouples,change their thread size according to the installation situation and temperature.When selecting the thermometer connector, be sure to make clear the thread of the thermometer.
The length of thermometer joint depends on whether the temperature measuring point needs thermal insulation.The length of temperature measuring point without thermal insulation is 60～80mm.The temperature measuring point that needs thermal insulation depends on the thickness of the insulation layer.Generally,it is better to expose the insulation layer for 30～50mm.The length of joint is generally 120～140mm,sometimes up to 200mm.Straight-type thermometer joints are widely used,and the temperature points on the equipment are straight.The thermometer installed on the pipeline can be 45 ° inclined type depending on the diameter of the pipeline,and the small diameter(≥∅80mm) can be used, but the temperature measuring element must be against the flow direction. If the pipe diameter is too small(≤∅80mm), the thermometer can only be installed with expanded pipe. When the pipe is ≥∅ 200mm,the straight connector can be used.When conditions permit,the thermometer installed on the elbow can reduce the requirement on the pipe diameter.
