| Mechanical vs. Electric Gauges |
|
|
|
We receive many questions asking which is better, electrical or mechanical gauges. Both mechanical and electrical gauges are equally accurate. The determining factors more involve installation and application than gauge accuracy. Our new "Full Sweep" electric gauges combine the electric gauge wiring with a full sweep dial face like the mechanical gauge. This short list of advantages should help you to make the decision for your specific application.

Mechanical Gauge Advantages
- Full 270° sweep, makes them easier to read accurately.
- Mechanical gauges do not require 12V power to operate. They make direct physical contact with the item they are reading. They do this through tubing or lines, which eliminates the need for electric signals.
- Ideal for vehicles that operate on voltages other than 12V, with no voltage at all (magneto applications) or operate on a battery with no generator.

Electrical Gauge Advantages
- 90° sweep.
- No large connectors and tubing coming out the back.
- Can be mounted in more unusual positions without connections showing.
- Easier to install in tight areas.
- Easier to install a great distance from the item being measured.
- Stops fluids from entering the passenger compartment.
