2264

The P-CapTM model 2264 accelerometer is a high performance and wide temperature range accelerometer intended to directly replace piezoresistive units for existing and new applications. It uses a capacitive sensing element and an advanced ASIC to simulate the operation of a piezoresistive bridge. 2264 is tailored for zero to medium frequency instrumentation applications. The anodized aluminum case is epoxy sealed and is easily mounted via two #4 (or M3) screws. Internal regulation is provided to eliminate the effects of excitation voltage variation. Unlike piezoresistive elements, 2264's sensitivity, bias and frequency response are insensitive to temperature changes or thermal gradients. The cable's shield is electrically connected to the case while the ground (GND) wire is isolated from the case. An optional initial calibration sheet (2264-CAL) and periodic calibration checking are also available.
