Different Types of Oil Pressure Gauges


The oil pressure gauge is considered to be one of the most important instruments helpful in maintaining an optimum health of your vehicle. It not only indicates variations in oil pressure but also gives prior intimations on any potential problems that might occur in future. This helps save time and money that might go into repairing an expensive breakdown. There are two types go gauge installed that are primarily used in vehicles today. One is called the mechanical gauge and the other is the electrical gauge. There are many websites available online that offer a comprehensive oil pressure gauge review which help understand the difference between the two.

Mechanical gauges are the one that are usually found in the older cars while the electrical ones due to its advanced make and construction are found in modern cars. The former consists of needle with a spring attached that shows variations with changes in oil pressure. While the later works on electrical signals sent to the gauge. Both types of gauges have their own pros and cons and it is. imperative to have a knowledge about them to understand the functioning of the gauge. One can refer to the various oil pressure gauge review available online to understand their working. Generally in a mechanical gauge there is a tapping through which the oil is sent to the gauge. The oil passes through pipes made from plastic or copper. These pipes are connected into the passenger compartment and further to the back of the gauge via a knurled connector.

Now the gauge contains a flex coil called the tube into which the oil is fed. Now when the oil enters with pressure it tries to straighten the bulb which in turn moves the needle inside the gauge on calibrated scale. With high and low pressure the needle moves accordingly. While the mechanical gauge due to its make and design is generally seen in old cars as discussed the electrical ones are seen in the modern version vehicles. These work on the principle of how much current flows through the gauge creating a magnetic filed which ultimately moves the needle on the calibrated scale. The variations in the movement of needle purely depends on the amount of current that flows through the gauge.

There are various pros and cons of using a mechanical and an electrical gauge. The former has a full sweep complete 270’ needle movement. While the later has a restricted needle movement of 90’-180’. Mechanical ones function via the tubes connected to the engine way while the electrical ones work on the sensor measurements installed in the engine bay. Be it a mechanical or an electric gauge these are illuminated for a better reading in the night. The bulbs used are generally connected to the side panel light circuit.
