Industrial microSD Used in Digital Tachometers

 

A tachometer calculates the revolutions per minute (RPM), of an object that spins. Most people are familiar with the tachometers found on car dashboards, which count the RPMs as they drive. However, these devices enjoy widespread use across multiple industries, in both consumer and industrial host applications. Because many digital tachometers work in rugged environments, it is important for OEMs to choose industrial grade memory that is capable of working in extreme temperatures and environments with high levels of shock and vibration. This is one of the reasons why industrial microSD cards are used in digital tachometers. If you’re looking for a flash memory solution for an industrial grade digital tachometer, here is what you need to know about using industrial microSD cards.

 

Spotlight on microSD Cards

Industrial microSD cards are the smallest version of the popular SD card, with specifications set by the SD Association (SDA). Since the SDA establishes the standards that all microSD cards have to follow, OEMs always know what they are getting and can rely on the compatibility of the cards in their designs.

 

The small size of microSD cards makes them well-suited for small form factor applications. This aligns with the design of most digital tachometers, so microSD cards are a natural choice for many host application designers.

 

Digital Tachometers and Rugged Environments

For industrial uses in particular, digital tachometers are often found in rugged conditions. They are widely used in trains, light rail vehicles, airplanes, and other forms of transportation. This usage means that they are exposed to intense levels of vibration and shock. Additionally, digital tachometers used in transportation often encounter high temperatures as well as rapidly changing temperatures. The embedded storage device must be able to perform read and write operations in these conditions.

 

Industrial microSDs Used in Digital Tachometers

Industrial grade microSDs are designed to meet all of the operating demands of digital tachometers in rugged conditions. Their small size allows them to easily fit inside devices with tight quarters. Industrial grade microSDs are designed with SLC flash, which is the most reliable version of flash memory available. These embedded storage cards can also tolerate temperatures that vary from -400 C to 850 C without any loss of function. Integrated Self-Monitoring, Analysis and Reporting Technology (SMART) is a special function that allows a memory device to automatically monitor its health. It also monitors the performance of the microSD cards, which can help to identify and address an issue before a failure occurs in the field.
