A fluid quality sensor system comprising a light source, a first light sensitive element disposed at a distance from the light source, forming a gap having dimensions suitable for permitting a fluid to flow therebetween, and aligned with the light source to receive light transmitted by the light source through the fluid, a second light sensitive element disposed perpendicular to a midpoint of a light path between the light source and the first light sensitive element, and a third light sensitive element disposed so as to form an acute angle at the midpoint with the light source.

Methods and apparatuses for magnetically detecting a temperature change for thermostat control thereof are disclosed. A thermostat control device can be configured to include at least one bi-metallic strip that is configured to experience a change in angular position in response to a temperature change. The thermostat control device is generally associated with a Hall sensor, which includes a plurality of magnets that can experience movement relative to the Hall sensor in response to the change in the angular position of the bi-metallic strip. The temperature change can then be automatically and/or electrically detected in response to the movement of the magnets, wherein the temperature change is utilized for thermostat control thereof.

A commutator assembly has a bracket for the placement and protection of Hall element sensors such as may be used for an electrical commutator assembly or other position locating device. The bracket features a surface containing encasements for each Hall element. The encasements have features for locating the Hall within the encasement by the center lead of each Hall element sensor, each Hall element sensor being spaced from one another at a predetermined distance according to said center lead locating features and being substantially surrounded by said encasement except for the forward surface of said Hall case. The bracket may further include a printed circuit board for electrical connections and an optical encoder assembly for supplementary position information.

A flow-through visible-light turbidity sensor is constructed from a molded plastic flow tube with an overmolded opaque housing to shield the optical sensing apparatus from ambient light. The housing also secures and covers all electronics for the sensor. The molded parts provide lower cost and less dimensional variation for the sensor as well as the ability to locate conductivity or other physical probe sensor types within the package.

Overmolded flowthrough turbidity sensor

An accelerometer is provided in which a magnet structure is encapsulated within a distal end of a cantilever beam that is formed as an integral part of a housing structure. The cantilever beam, the distal end and the housing structure are formed of a nonmagnetic material, such as plastic, during a single injection molding procedure. The magnetic structure within the distal end of the cantilever beam can comprise two magnets associated with a pole piece and disposed within an opening formed in a nonmagnetic bracket. Although many types of magnet structures are possible within the scope of the present invention, a particularly preferred magnet structure comprises two magnets that are arranged in opposite polarity with the opposite poles of the two magnets being located adjacent to each other on opposite sides of a centerline. The magnet structure can be held in place during the injection molding process by the magnetic attraction between the magnet structure and a ferromagnetic portion of the mold. The magnetically sensitive component, which is held in place within a wall of the housing structure, can be a Hall effect element.
