A dielectric-constant-insensitive fluid level sensor for directly inserting into a high dielectric constant fluid is disclosed. According to one embodiment, the fluid level sensor includes a first set of stacked series capacitors where each capacitor in the first set is formed by two coplanar electrodes and a dielectric space between the electrodes. Each stack of series capacitors in the first set includes at least one capacitor having a first molded carrier as the dielectric space in series with another capacitor having a first fluid cavity as the dielectric space. In this embodiment, the total capacitance of the first set of stacked series capacitors varies as a function of the level of the fluid within the first fluid cavity.

A pressure sensing apparatus with multiple, isolated pressure sensors provided therein. The apparatus includes a base cover portion having multiple sections and each section defines an opening. A sensor is positioned in each base cover portion and a portion of each sensor is exposed to the respective opening. A flanged base is coupled to the base cover portion to define multiple separate chambers and a housing is provided around the base cover portion and base and the housing has multiple conduits in fluid connection with respective cover openings.
