INDUSTRIAL AND TEST & MEASUREMENT
MEMS DC ACCELEROMETER MODULES
All SDI Industrial and Test & Measurement MEMS DC Accelerometer Modules incorporate the company's own highly rugged, low-noise surface mount accelerometer chips for precise and dependable full-scale measurements ranging from ±2g to ±400g. This feature makes the modules suitable for use in most low-to-medium frequency applications, and with measurement accuracy down to DC (0 Hz). Internal amplifiers and power regulation eliminate the need for extra equipment. Each unit undergoes 100% factory testing and calibration prior to factory shipment.

SPECIALTY +5V EXCITATION POWER, 1" SQUARE
The 2012 was made for systems where the power supply is limited and only requires excitation with a steady +5V DC. It's built with a traditional 1" x 1" x 0.3" package and 3' integrated cable.
PROVEN APPLICATIONS:
· simulator sensors
· infotainment system development
· automotive vibration
· education
· flight test data
LOW COST, UNIVERSAL 1" SQUARE FOR STANDARD TEST & MEASUREMENT APPLICATIONS
The 2210 is SDI's #1 selling 1-axis module. It's a rugged, low-cost workhorse in a traditional 1" square package with a 3' integrated cable. The 2210 is an excellent choice for most 1-axis test and measurement applications. The 2210 is fully potted for added resilience.
PROVEN APPLICATIONS:
· rail monitoring
· agricultural machinery testing
· active suspension feedback system
· validation testing
· crash sled instrumentation
HIGH-PERFORMANCE 1" SQUARE FOR TEMPERATURE-SENSITIVE APPLICATIONS
The 2220 is SDI's upgraded version of the 2210. They use SDI's 1522 accelerometers, which are individually temperature tested and screened to provide half the bias and scale factor over temperature, and then potted in the case. Use the 2220 if your application involves rapid swings in temperature or long periods of time at the far ends of the range.
PROVEN APPLICATIONS:
· aircraft vibration testing
· wind turbines
· race car monitoring
· aerial firefighting equipment
· semi truck stability tests
HERMETIC, HIGH-PERFORMANCE 1" SQUARE FOR HARSH ENVIRONMENTS
The 2240 is internally identical to the 2220 but housed in a very rugged, hermetic, titanium case. The connector allows for easy cable changes, and the 2240 is capable of IP67 if the connector is sealed.
PROVEN APPLICATIONS:
· UAV wing instrumentation
· spacecraft vibration
· airplane engine vibration
· boat & ship instrumentation
· aerospace landing gear
LOW COST, UNIVERSAL SMALL FOOTPRINT FOR STANDARD TEST & MEASUREMENT APPLICATIONS
The 2260 is the skinny version of the 2210 and the lowest mass module SDI builds. The 2260s are operationally identical to the 2210s, but they are built into small footprint packages for use in tight spaces or lightweight applications. They come with an integrated 3' cable and are fully potted.
PROVEN APPLICATIONS:
· interactive theater seat controls
· ride comfort & NVH
