产品描述

The ACC141 Series are linear accelerometers that produce a high level output proportional to the instantaneous acceleration from static to 3000 Hz (depending upon range). The excellent dynamic response is enabled by using air damping which has much better temperature properties than fluid damping. The rugged capacitive sensor allows the high overload properties and delivers excellent accuracy and long term stability. The rugged stainless steel case with O-ring seal provides excellent environmental protection and the integral base plate make installation and mounting quick and isolates the unit from mounting strain.
