JHT-I-H-3 High precision Tri-Axis digital accelerometer

1. Product overview

JHT-I-H-3 High precision Tri-Axis digital accelerometer is composed of three high-precision quartz flexible accelerometers in three orthogonal directions. The output circuit is equipped with high-precision platinum resistance, the output of the accelerometer is collected by 24bit AD, and the digital signal is compensated in full operating temperature range.

Features: High precision, Digital output, Complete temperature compensation and calibration, Excellent long-term stability.
