Oil level sensors are frequently used for industrial and automotive applications. They help to gather and send useful information. Different types of oil level sensors are available. While some are simple, float-type level indicators, others are quite complex.
The oil tank level sensor is an oil level controller that opens and closes circuits based on the rise and fall of oil levels. Oil pumps can be automatically turned on or off with the opening and closing of circuits.
Working of Oil Level Sensors
Magnetic reed switches are used in oil level sensors to measure the level of oil. As the switch moves up and down to break circuits, in accordance with the changes in oil level, the pumps are turned on or off. When the oil reaches the lowest point in the tank, the reed switch helps to create a circuit. Thereafter, a signal is automatically sent to the pump to start filling the tank.
When the oil level touches its maximum capacity, the alarms remain switched off. But, when the oil level starts reducing, it sounds like a low-level alarm. This sends the signal to start refilling the tank. As the oil touches its maximum level, the alarms are switched off and indicate the pump to stop filling further.
Types of Oil Level Sensors
The most widely used level sensor is a mechanical sensor. It involves the opening and closing of a mechanical switch. The operation of magnetically actuated float sensors is different from that of mechanically actuated floats. For high viscosity or thick oils, float sensors are not the best choice. They have a tendency to develop sludge. However, it is quite useful for the determination of the interface level in oil-water separation systems. The magnetic float switches are quite popular owing to its lower cost, simplicity, and reliability.
Pneumatic level sensors are preferred for applications where heavy slurry or sludge is used. It is perfect for places where hazardous conditions exist or where electricity cannot be used. It is often chosen for viscous liquids such as grease. It is also preferred due to its economic cost of operation.
Another type of oil level sensor that is frequently used is an ultrasonic level sensor. It is used for bulk solids and extremely viscous liquids. It emits high-frequency acoustic waves which are reflected to determine the oil level. Its response is often affected by the presence of chemical mists, foam, turbulence or steam. It prevents the sound waves from being easily reflected to the sensor.
