What does air core mean in gauges?
An air core gauge is a specific type of rotary actuator in an analog display gauge that allows an indicator to rotate a full 360 degrees. It is used in gauges and displays, most commonly automotive instrument clusters.
What is an air core motor?
Air-core movements (air core motor) are robust gauge mechanisms commonly used in automotive and marine gauges. An air-core is simply a very basic electric “motor” with a permanent magnet rotor and no commutator brushes. It’s called an “air-core” because there is no iron in the magnetic path.
How an air core works?
An air core, at its essence, is a small magnetic core with copper windings around it that will move in relationship to voltage it sees. This is regulated by an electronic sending unit, which will change its resistance to ground based on the reading.
What is a short sweep gauge?
A Short Sweep Electric (SSE) or Air-Core gauge is at its essence, a small magnetic core with copper windings around it that will move in relationship to the voltage it sees. This is regulated by an electronic sending unit, which will change its resistance to ground based on the reading.
What is a stepper motor gauge?
The Stepper-Motor gauge is the latest evolution in gauge design. It utilizes microprocessors for operation. Stepper-Motor gauges are controlled by a microprocessor that utilize laboratory-grade sending units for the ultimate in accuracy.
Are mechanical or electric gauges better?
Is an Electric Gauge More Reliable than a Mechanical Gauge? However if there’s a failure, mechanical gauges can cause much more damage than electric gauges. It’s for this reason that we do not recommend installing mechanical fuel or oil pressure gauges inside the cabin.

Can you make an air core gauge driver?
Thank you for your advice, especially if you are already experienced designing air-core gauge drivers. These are pretty specialized products and are not very likely to be used by a broad range of customers so stock at disties my not be as good an indication of status as usual.
Why are air core instruments called air core?
The Air-Core Approach Air-core movements are robust gauge mechanisms commonly used in automotive and marine gauges. An air-core is simply a very basic electric “motor” with a permanent magnet rotor and no commutating brushes. It’s called an “air-core” because there is no iron in the magnetic path.
How does the cs8190 air core meter work?
The CS8190 takes a speed sensor input and generates sine and cosine related output signals to differentially drive an air-core meter. Many enhancements have been added over industry standard tachometer drivers such as the CS289 or LM1819.
How many signals does an air core need?
The air-core movement itself requires two signals to drive it, one for each coil. You could drive it using two channels from something like the EPIC gauge module, though that would be rather expensive. (The EPIC gauge module is designed to make use of the National LM-1819.
