Dytran Instruments have recently released a new range of lower cost DC accelerometers to complement their ever-growing range of MEMS type sensors. This 7300A series of accelerometers offers nearly the same low noise outputs as their titanium bodied models, but in a more cost effective package. These sensors are designed to operate with a differential output, however can be used single ended but with a lower output sensitivity.

The Dytran 7300A series accelerometers are packaged in a lightweight (12 grams) blue coloured anodised aluminium housing, with a vertical height of 8.9mm and a body size 22.9 x 22.9mm square. Mounting is via two 4.2mm diameter holes, and a 4-pin radial connector interfaces the signal and power.

A separate mating cable assembly is available. The sensors are case isolated and are epoxy sealed, and have an operating temperature range from -55 to +125 degC. The 7300A series comes in eight different ranges from +-2g through to +-400g, with sensitivities from 2V/g through to 10mV/g for the highest range.

The frequency response also varies depending on range from zero to 400Hz, and up to 2.5 kHz for the higher ranges. Most of the 7300A accelerometers have a 5000g shock limit, but the 2g and 5g range sensors are limited to 2000g. These types of accelerometers are used for low frequency dynamic and steady state acceleration events, such as modal and structural analysis, ride quality, road load and tilt and inclination measurements. Please ask for further details of these DC accelerometers, or supply details of any application you may have, so that we can advise on the best accelerometer solution.
