Mechanical vs Electrical Gauges

DMComponents are well known for its great range of mechanical and electrical gauges. As a leading supplier and manufacturer of a range of products, DMComponents offer gauges for a number of market sectors such as automotive, marine, commercial and industrial. This week we are looking at the differences of mechanical and electrical gauges, and why you may use one over another.

Referring to a gauge as either electrical or mechanical simply means the way in which the gauge gets information. The type of gauge you decide to use, no matter if it is a fuel, temperature or pressure gauge will vary depending on your requirement. DMComponents has found that its customers tend to use mechanical gauges in vintage cars for authenticity. A mechanical gauge in this situation can seem as a more traditional instrument to use, and really brings to life the authenticity of the classic vehicle. Using a mechanical gauge in this situation, DMComponents believes really helps to appreciate the original look and style of your vintage car. While customers in this situation do tend to opt for mechanical gauges, electrical can be used, it’s a matter of your personal preference.

However, a clear disadvantage of using a mechanical temperature or pressure gauge is the setup and installation. A mechanical temperature gauge comes as one unit, meaning the temperature and calibrator tube all feed as one to the sender. Also, mechanical pressure gauges must be connected by tubing directly to the engine block to get a direct measurement whereas an electrical gauge is seen as less bulky, much easier for you to route and takes its measurement using a sensor installed in the engine block. This is typical for either a temperature or pressure gauge. With a mechanical gauge in essence being more complicated, it can take longer for you to install this type of gauge. In this instance, your preference on which gauge to use really does depend on the time you have to install the gauge.

A lot of DMComponents customers swear by mechanical gauges, while others are happy with using electrical versions or opt for electrical gauges for their modern vehicle. We want to reach out to all types of customers and that is why we choose to offer both mechanical and electrical gauges. Something DMComponents believe is important to note is both types of gauges have electric wire connections. This is needed to provide you with light for night time use of your vehicle.
