Measuring apparatus for a level indicator design, in particular for flue sig as a function of the casing in motor vehicles

摘要

This sensor comprises two tubular insulating substrates made of glass or of enamelled sheet on which are deposited by screen printing inks of the superposed layers of conductive and insulating, in order to form a resistor and a conduction path. These two substrates are held against each other, screen printed faces towards the outside, by bonding or screwing onto a metal plate of suitable shape for the guidance of a float having 2 slides displaceable along the strip as a function of the level of liquid, so as to obtain a resistor whose value varies proportionally to the level br / & this assembly is placed inside a tube comprising at its lower part, a calibrated orifice. & br / (see appended drawing in bopi) & br / & & br /
