New low-cost high-performance tri-axial DC accelerometer

Silicon Designs has introduced four new low-cost high-performance tri-axial DC accelerometer families. The integrated plug-and-play vibration measurement devices are suitable for zero-to-medium frequency commercial and industrial applications, and particularly, where performance reliability, low noise, and long-term stability are absolute requirements. Newly redesigned SDI models 2460 and 2466 offer reliable performance, extremely low noise and long-term stability at a low cost. In addition, Models 2470 and 2476 are operationally identical to those of the 2460 and 2466, with the added inclusion of initial calibration certificates, greatly reduced bias and improved scale factor temperature shift specifications. Small-to-medium sized quantities are available from stock. The 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 aluminium 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 2000Hz). 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 -55C to +125C.
