Stabilizing DC Motor’s Speed using ZTX450 NPN Silicon Planar in Bridge Circuit
The following article will describe you with how to stabilize DC motor’s speed using ZTX450 NPN silicon planar transistors in bridge circuit. The circuit description is to improve the load/speed regulation of a DC motor by cancelling out the effect of the motor rotor resistance using a bridge circuit. The circuit diagram above illustrates the DC motor speed control circuit with the bridge circuit within. You will find detail explanation a… 0, 1.22, 0, 1, diagram: 1
How is the Mechanism of Low Engine Oil Pressure?
The oil pressure warning device provides vital information if there is an indication of low or no oil pressure when the engine is running. It is a serious problem since the oiling system must be properly pressurized to keep the moving parts of the engine lubricated to prevent excessive wear. As seen in the schematic diagram, oil pressure indicator is connected with a pressure switch. It sends a signal when the oil pressure is below 5 PSI (3.5 k… 0, 1.22, 0, 1, diagram: 1
How to Design an Automatic Fuel Level Monitoring-Circuit System in Gas Station Tank
Here we find an article that explains you about how to design a system that will measure the level of fuel in the tank (maybe gas station) and send it automatically to computer-monitoring system. Below is the circuit diagram of the monitoring device. The circuit will need a 240v supply which will step-down to 24V by a transformer and further be rectified using diodes (IN4007) to DC voltage. According to the article, you will need such 470µ… 0, 1.22, 0, 1, diagram: 1
