    The measuring part is composed of one or more elements from prismatic borosilicate glass (crystal) which trigger the reflection or non-reflection of the environmental light depending on whether the inner surface comes or does not come into contact with the fluid or with the gas (vapor). The crystal is tightened to the inside of a steel box by means of bolts. Its sturdy construction and its good visibility, without using dedicated illuminators, make it ideal for use in heavy-duty applications with pressure up to 400 bars and temperature up to 427° C.
