Product Description

BWH520 High-Precision Voltage Dual Axis Inclinometer Accuracy: 0.003° Ip67 Industrial Automation Attitude Control




BWH520 is a dual-axis high-precision inclination sensor with MEMS technology and voltage output has high cost performance, with a measurement range of ± 30 ° and an accuracy of 0.003 °. It is a product with high cost performance. The internal use of high-resolution differential fractional analog converter, built-in automatic compensation and filtering algorithm, effectively reduce the error caused by environmental changes. It is suitable for industrial automation, surveying and mapping and other industries.
