The 100% veteran owned and U.S. based Silicon Designs, Inc., leading designers and manufacturers of industrial grade MEMS capacitive accelerometer chips and modules, today announced the global market introduction of six new series of low-cost, high-performance MEMS capacitive accelerometers, in both traditional and smaller footprints.
These include the single axis Model 2220 or triaxial Model 2470, featuring aluminum housings and a standard 1 meter integral cable; the single axis Model 2240 or triaxial Model 2480, featuring hermetically sealed titanium housings and an integral connector; and the single axis Model 2276 or triaxial Model 2476, featuring aluminum housings and an integral connector.
Each model is offered in full-scale standard ranges from ±2 g to ±400 g, along with choice of ±4V differential or 0.5V to 4.5V single ended output. Their expanded temperature performance to +125°C, as well as improved scale factor and bias temperature shifts, allows them to provide excellent long-term stability with an industry-best-in-class price-for-performance ratio. The accelerometers are also relatively insensitive to temperature changes and gradients.
Depending upon selected model, units feature a simple four-wire (single axis) or eight-wire (triaxial) connection; flexible response to either DC or AC acceleration (0-2000 Hz); low-impedance outputs, supporting up to 2000 feet of cable; and flexible operation from +8 to +32 VDC power.
Each device is marked on its top and bottom surfaces with a serial number for traceability. A calibration test sheet is supplied with each unit, showing measured bias, scale factor, linearity, operating current, and frequency response. A simple test sequence, using the earth’s gravity, may be used to verify operation and calibration. Additional features and customization may be available. Please consult Silicon Designs for details.
Based outside of Seattle, Washington, Silicon Designs specializes in the design, development and manufacture of high-reliability MEMS capacitive chips and accelerometer modules. On-board voltage regulation and an internal reference minimize temperature and voltage changes while eliminating additional external power regulation requirements.
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 capacitive accelerometer chips and modules, Silicon Designs can further ensure product quality and custom design capabilities, while keeping its lead times and prices highly competitive.
