The design of the thermometer probe

General users are hoping to probe thermometer response fast, firm structure, high precision. Rapid response of the probe, however, tend to be unstable, and the firm structure of probe its precision and sometimes have a problem, such as the provisions of the can't satisfy the insertion depth and so on. In addition, the structure of the probe itself will lead to all kinds of error, such as low insulation resistance, parasitic potential, casing or lead solder joints from corrosion, solder joint plug contact resistance and contact resistance change, etc. Some production methods in the error caused by the probe itself has made great progress. Multi-strand wire may be caused by several strands break resistance change, and the user is not easy to detect the change again. Single core wire is either good or bad, will not be not sure of the 'grey area'. Lead and element of welding capacitor discharge type spot welding. To prevent the oxidation of the solder joints, welding in the gas protection. Welding parameters is defined for each component in detail, such as welding voltage, welding pressure, electrode form, etc. , in particular to pulse width of welding, because every manufacturer with different types, different diameter wire. With each other for some gold welding, welding pulse width is very important, but the parameters in spot welding machine is not adjusted. In normal circumstances, the components of the insulation resistance is very high, but it according to the exponential function decline in high temperature. In addition, using the bo rui adhesive to bond element also can reduce insulation resistance, because if the element is in the process of manufacturing badge salt glass without baking, well this kind of glass has hygroscopicity, from high absorb water as it cools. 一般温度计用户预计将探针快速响应,固体结构,精度高。 然而,快速 响应探测器通常是不稳定的,同时, 结构化的调查有时有精度问题,如不满足插入深度要求。 此外,探测器本身的结构会导致各种错误,如低绝缘电阻,产生寄生潜能,套管腐蚀或铅焊点,焊点接触电阻和插头接触电阻变化。 一些生产方法已经取得了很大的进步在消除探测器本身造成的错误。 多个领导可能会改变电阻由于一些优惠,由用户,它不容易被察觉。 单 核心领导是好是坏,没有“灰色区域”是不确定的。 电容器放电点焊的铅和组件。 为了防止焊点的氧化,与气体保护焊。 等焊接参数、焊接电压、焊接压力和电极类型,指定详细的对于每一个组件,尤其是焊接脉冲宽度,因为每个制造商使用不同类型和直径的导线。 脉冲宽度对一些金属——非常重要 - 金属焊接,但不能调整这个参数一般点焊机。 通常,元素的绝缘电阻非常高,但在高温下指数降低。 此外,使用粘结剂硼债券组件也会降低绝缘电阻,因为如果硅酸盐玻璃没有烤在制造过程中,玻璃时吸湿和吸收大量的水从高压冷却。
