June 14, 2017 –Silicon Designs, designers and manufacturers of industrial grade MEMS capacitive accelerometer chips and modules, announced the global market introduction of six series of 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.
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; 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.
