Fuel Level Sender-Inside Story

Needless to say, all equipment powered by an internal combustion engine needs a means of fueling to operate efficiently for as long as possible. ICE is used in cars, motorcycles, race vehicles, ATVs, utility vehicles, compressors, generator sets, etc., but the problem that is always involved is knowing how to contain fuel, how much is left and how best to do it. That is. It should be stored for the benefit, security and security of the user.

The fuel container is usually steel or plastic. Although these materials are traditionally used and relatively inexpensive, many modern race fuels contain highly aggressive additives, so these tanks may be made of carbon fiber or made of carbon fiber. Must be reinforced with Kevlar. Truck and heavy truck fuel tanks are often rectangular and have few baffles or stiffeners to block the sender’s float arm, making it easy to install a simple swingarm type fuel level sender. This sender normally outputs an ohm value to the gauge, but it has a unique failure due to fuel sloppy and the resistance track is constantly wiped by the float arm, which shortens the sender’s useful life.

In modern vehicle design, designers need to be increasingly creative and adapt the tank profile so that it does not affect the vehicle’s increasingly complex aesthetics. Swingarm senders are not suitable for this type of tank, so you can use solid-state electronic sensors and senders that can be programmed into the tank profile to accurately read fuel levels. In addition, advanced electronic engine management systems required a voltage or PWM (Pulse Width Modulation) input that was not available from the swingarm sender. Therefore, the capacitive level sender is an ideal product to meet all the technical demands of today, as there are no moving parts to wear. Capacitive technology is reliable and well-proven. The output on the transmitting side matches all analog and digital ECU inputs. It can be programmed to correct irregular tank shapes and smooth the blip caused by fuel sloppy, and has many other features.

Over the past few years, fuel costs have risen and their theft has been a major factor in how tanks are secured. One of the most commonly used methods is to place the fuel filler neck behind the lockable panel. The second method is to install a siphon protection device. In addition, the designer can specify the installation of a capacitive fuel level sender that can output the level to the remote monitoring telemetry system so that regular readings of the fuel level can be recorded and if a sudden drop in level is observed. This will quickly investigate the loss of fuel that may indicate the theft and cause. In addition, vehicle applications can accurately measure fuel consumption and provide information indicating whether it is being operated in an economical and appropriate manner.

For example, the fuel supply process is considered to be less relevant than emission regulations, but this article shows that industrial equipment customers are more concerned with this aspect of product design. A new and rewarding application.
