How to Choose Between A Digital Stepper Motor, Air Core, and Mechanical Gauge
Movement is the heart of a gauge that can’t operate without it. But there are so many kinds of movements, which one should we choose? We will introduce and explain mechanical instruments and various meter movement used in the construction of our electrical instruments.
STEPPER MOTOR MOVEMENT
THE LATEST EVOLUTION DESIGN - STEPPER MOTER GAUGE
Stepper motor movement represents the pinnacle of single gauge technology and provides the highest level of accuracy, precision, responsiveness and durability. Each instrument is controlled by a microprocessor printed internally on the circuit board,
which allows incredibly fast calculations and many other particular functions not seen in other instrument types. These gauges send units for the ultimate in accuracy by utilizing laboratory grade, no more than +/- 1%. To further increase accuracy, every time the gauge is powered up it will zero calibrate to assure that it will always remain as accurate as it was the day it was made.
WHAT WE HAVE
AIR CORE
MOVEMENTS ARE DURABLE, AFFORDABLE AND VERY SUITABLE FOR MOST STREET AND MILD RACE APPLICATIONS.
An air core is essentially a small magnetic core with a copper winding around it, which will fluctuate with the voltage it sees.
When the temperature or pressure changes, the meter will measure the resistance, so that the voltage seen by the air core will change,
it will also indicate the indicator to move to the calibration position on the dial.
MECHANICAL
The biggest advantage of the mechanical gauges is they can be utilized without being connected to the car’s electrical system & Always on.
These gauges have a direct connection (via a tube or capillary) to the engine. When the fluid or gas expands inside the tube, the bourdon inside the gauge also expands or contracts driving the gear train, which then turns the pointer. An advantage to mechanical gauges is they can be utilized without being connected to the car’s electrical system. This is great for a race car, as when the car is shut off in the pits, the gauge will still display the current temperature.
To sum up, the mechanical instrument has the following advantages.
1.Great accuracy 2.full dial-sweep 3.always on 4. It has a direct, physical connection to an engine.
But Some people believe that electrical gauges are better because the fluid-filled lines of a mechanical gauge can be ruptured.
Overall, we would highly recommend the electronic stepper motor movement instrument.
Because if you compared with other movements, the electronic stepper motor movement
instrument is more versatile in function, with advanced functions such as warning, recall and electronic device control.
It also provides the highest level of accuracy, precision, responsiveness, durability and it is very easy to install.
