Abstract

The present disclosure provides for systems and methods for fabricating sensing and/or control device assemblies, e.g., a dual pressure switch sensing and/or control device, a dual temperature switch sensing and/or control device or the like. More particularly, the present disclosure provides for systems and methods for fabricating sensing and/or control device assemblies (e.g., dual switch sensing and/or control device assemblies) with adjustment features and/or functionalities for switch calibration and/or adjustment. In one embodiment, the present disclosure provides for systems and methods for fabricating sensing and/or control device assemblies (e.g., dual switch sensing and/or control device assemblies) with rotary adjustment features/functionalities wherein the switches of the sensing device may be calibrated or adjusted via the rotary adjustment features/functionalities.

Dependent claims

A sensing device comprising:

a first housing attached to a coupling having an inlet, the first housing configured to house at least in part a condition responsive actuatable sensing element, the actuatable sensing element having a first end and a second end, the first end in communication with the inlet;
a second housing mounted with respect to the first housing, the second housing including a groove configured to house at least in part an electrical mounting member, the electrical mounting member:
(i) having a top side and a bottom side, and (ii) having at least one switch secured to the bottom side of the electrical mounting member, the at least one switch including a switch actuator;
wherein the second housing has a proximal side defining a first horizontal plane and a bottom side defining a second horizontal plane, and wherein the groove is angled relative to at least one of the first and second horizontal planes;
and
wherein the electrical mounting member is configured to be positioned within the angled groove and rotated within the angled groove without being moved in the axial direction of the electrical mounting member and with respect to the second housing to thereby adjust the height of the switch actuator relative to the second end of the actuatable sensing element.

A method for fabricating a sensing device comprising:

providing a first housing attached to a coupling having an inlet, the first housing configured to house at least in part a condition responsive actuatable sensing element, the actuatable sensing element having a first end and a second end, the first end in communication with the inlet;
providing a second housing mounted with respect to the first housing, the second housing including a groove configured to house at least in part an electrical mounting member, the electrical mounting member:
(i) having a top side and a bottom side, and (ii) having a first switch and a second switch secured to the bottom side of the electrical mounting member, the first switch including a first switch actuator and the second switch including a second switch actuator;
wherein the second housing has a proximal side defining a first horizontal plane and a bottom side defining a second horizontal plane, and wherein the groove is angled relative to at least one of the first and second horizontal planes;
positioning the electrical mounting member within the angled groove;
rotating the electrical mounting member within the angled groove without moving the electrical mounting member in the axial direction of the electrical mounting member and by rotating the electrical mounting member with respect to the second housing to thereby adjust the heights of the first and second switch actuators relative to:
(i) one another, and (ii) the second end of the actuatable sensing element;
securing the second housing relative to the first housing after the desired position of the electrical mounting member has been determined by a user;
and
securing the electrical mounting member with respect to the second housing after the desired position of the electrical mounting member has been determined by the user.
