MEMS accelerometer 7300A5

single-axiscapacitive

OVERVIEW The Dytran model 7300A5 is a high precision single axis variable capacitance (VC) accelerometer available with a range of 50g with a 4-pin 1/4-28 radial connector. These high performance accelerometers combine an integrated VC accelerometer chip with high drive, low impedance buffer for low level acceleration measurements. Tailored for zero-to-medium frequency applications, the model 7300A5 features a low end frequency response of 0 Hz (DC) and upper frequency range of 2,000 Hz. This module contains a MEMS capacitive sensing element, a custom integrated circuit amplifier, and differential output, packaged in a rugged aluminum housing weighing 13 grams. Units are easily mounted via two 8-32 screws. On board regulation is provided to minimize the effects of supply voltage variation, and the model 7300A5 is relatively insensitive to temperature changes and thermal gradients.
