New Low-Cost and High-Performance Triaxial DC Accelerometer Families

All SDI MEMS triaxial accelerometer modules offer highly reliable and cost-effective acceleration and vibration sensing. Their designs incorporate three orthogonally mounted low-noise single axis accelerometers into a single rugged, epoxy sealed anodized aluminum case. They are offered in standard ranges from ±2 to ±400 g and with choice of ±4V differential or 0.5V to 4.5V single ended output. Low-impedance outputs support up to 2000 feet of cable. Units feature a simple eight-wire connection, and respond to both AC and DC acceleration (DC to 2000 Hz). Onboard voltage regulation and an internal voltage reference eliminate the need for precision power supplies. They are also relatively insensitive to temperature changes and gradients, and operate over a standard temperature range of -55°C to +125°C.

Based outside of Seattle, Washington, USA, Silicon Designs specializes in the design, development and manufacture of high-reliability MEMS variable capacitive chips and accelerometers. All products are 100% made in the USA. Carefully regulated manufacturing processes ensure that each sensor is made to be virtually identical, allowing users to swap out parts in the same g range with few to no testing modifications, further saving time and resources. This also provides test engineers with a quick plug-and-play solution for almost any application, with total trust in sensor accuracy when used within published specifications. As the OEM of its own MEMS VC accelerometer chips and modules, Silicon Designs is able to ensure quality, offer custom design, and still keep prices highly competitive. Standard MEMS variable capacitive accelerometers are available with full-scale sensitivities from 2 g to 1,000 g. Within the standard range (2 to 400 g), most Silicon Designs MEMS accelerometers can continue to operate within specification after sustained exposures of up to 5,000 g and limited exposure to temperatures to +150°C.

Silicon Designs triaxial variable capacitance accelerometers support a wide range of applications, including UAV inertial measurements, robotics, seismic studies, crash event detection, missile launches, downhole vibration, automotive testing, motorsport, shipping container monitoring, airplane flutter testing, turbine engine precession, and civil structural integrity monitoring.
