The basic dry run protection circuits using BJTs shown here provide simple ways to check for low water levels in an underground tank but without needing to use probes inside […]
IC 555 Dry Run Protection Circuit
An preexisting circuit for an IC 555-based water level controller may be modified to include the dry run protection, as seen below: In the schematic above, the dry run function […]
Current Sensed Motor Dry Run Protector Circuit
Commonly dry run circuits mostly rely on water detection, which renders the designs quite antiquated and laborious. In contrast to these concept, the subsequent one relies on either load or current sensing […]
Dry Run Protection for Motor using Reed Relay Switch
When there exists no water in the tank and zero water is flowing out of the pipe plug, the pump motor could be equipped with an efficient dry run protection […]
Motor Dry Run Protection Circuit using IC4049
Six NOT gates from the IC 4049 may also be used to create a completely automatic version of a motor dry run protection circuit as seen below. This setup should operate […]
