<p>The signal/warning system is for milking equipment to inform the operator automatically when milk is being lost by being pumped into the rinsing water vessel. It includes a membrane switch which is under voltage only when the equipment is switched on for milking. When a sufficient rise in milk level has been achieved in the rinsing water vessel during the first minutes of pumping, sufficient pressure is built up to operate the membrane switch. Accordingly a klaxen is sounded to alert the operator.</p> |
