PRESSURE TANK FAULT DETECTOR AND METHOD

摘要

A pressure tank fault detector and method provides a system (10) for detecting a fault in a pressure tank (12). The system includes a current transformer (40) positioned adjacent a pump power wire (22). A circuit (42) includes a timer (44), a data recorder (46), and a system status indicator (48). When the pump (18) operates, the current transformer (40) signals the circuit (42) and the timer (44) measures the signal duration. The data recorder (46) logs a short cycle when the timer (44) measures less than a selectable predetermined amount of time. When two or more short cycles are recorded, an alarm is produced. Preferably, the system (10) includes a test circuit (74) and allows selection of the number of short cycles before the alarm and whether to record only consecutive short cycles. Optionally, the system (10) detects and signals pump cycles exceeding a predetermined excessive run time.
