摘要: A high-reliability, high-temperature liquid level detection probe uses a metal ring to hold prism in the body. The forms an interference fit with both and body metal/prism metal/metal seals remain effective even at elevated temperatures so that contamination of electronics is prevented. circuit board on which are mounted enclosed holder potting compound used seal electrical wires entering does not contact or board. Thus, free move response expansion contraction damage
