<\/span>First, the test<\/span><\/h2>\nThe mineral oil retailer’s tank truck driver comes to deliver. He creates an electrical connection<\/strong> between the limit indicator and the tank truck. Before he can fill, however, he must first check the functionality of the limit indicator with its overfill prevention<\/a>. The applied voltage ensures that the PTC thermistor is heated up. If the safety device passed the test successfully, there is nothing preventing the filling process.<\/p>\nAs soon as fuel oil reaches the PTC resistor<\/strong>, this changes the current in the electric circuit between the limit indicator and the control unit on the tank truck. Within a very short time, this change causes the filling process to be stopped and no more fuel oil flows into the tank.<\/p>\n\nYou might also be interested in<\/span><\/p>\nDiscover more helpful content on this topic.<\/p>\n
