Abstract
Systems and methods for a solenoid supervisory detection system which can detect the presence or absence of a solenoid plunger within a solenoid coil. These systems can be used to verify correct reassembly of a solenoid valve after it has been disassembled for testing.
Claims8
A system for detecting the presence of a solenoid plunger within a solenoid coil, the system comprising:
- a solenoid coil assembly comprising a solenoid winding within an electrical insulator which is within an electrically conductive coil case;
- a power source electrically connected to said electrically conductive coil case;
- and
- a solenoid plunger assembly comprising said solenoid plunger within an electrically conductive valve housing;
- wherein, when said solenoid plunger assembly is correctly positioned within said solenoid coil assembly, said electrically conductive coil case is in electrical communication with said electrically conductive valve housing.
