    • A high-reliability, high-temperature liquid level detection probe uses a metal ring to hold a level detection prism in the probe body. The metal ring forms an interference fit with both the prism and the probe body and the metal/prism and metal/metal seals remain effective even at elevated temperatures so that contamination of the probe electronics is prevented. The probe electronics and the circuit board on which the electronics are mounted are enclosed in a holder so that the potting compound which is used to seal the electrical wires entering the probe does not contact the electronics or the circuit board. Thus, the circuit board and electronics are free to move in response to expansion and contraction of the potting compound and damage to the electronics and circuit board is prevented.
    • 高可靠性,高温液位检测探头使用金属环在探头体内固定液位检测棱镜。 金属环与棱镜和探头本体形成过盈配合,金属/棱镜和金属/金属密封件即使在高温下也能保持有效,从而防止探头电子部件受到污染。 探头电子元件和安装有电子元件的电路板封装在一个支架中,以便用于密封进入探头的电线的灌封料不会接触电子元件或电路板。 因此,电路板和电子器件响应于灌封化合物的膨胀和收缩而自由移动,并且防止了电子器件和电路板的损坏。

    • 高可靠性的高温液位检测探头使用金属环将探测器主体中的液位检测棱镜固定。 金属环与棱镜和探头主体形成过盈配合,并且金属/棱镜和金属/金属密封件甚至在升高的温度下也保持有效,从而防止了探针电子器件的污染。 探针电子设备和电子装置安装在其上的电路板被封闭在保持器中,使得用于密封进入探头的电线的封装化合物不接触电子器件或电路板。 因此,电路板和电子器件响应于灌封组合物的膨胀和收缩而自由移动,并且防止对电子器件和电路板的损坏。
