1. a device that produces regular pulses or rhythmic beats
Usage: technical
2. a mechanism in milking machines that creates the vacuum pulses needed for milking
Usage: agricultural; technical

Examples

• The pulsator in the milking system needed regular maintenance.
• Engineers tested the electronic pulsator for consistent timing.
• The dairy farm replaced the old pulsator with a more efficient model.
• A faulty pulsator can disrupt the entire milking process.
• The pulsator generates precise vacuum cycles for optimal milk extraction.
