BWM420 Cost-effective Dual-Axis Voltage Output Inclinometer Technical Manual

Cost-effective Dual-Axis Voltage Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWM420 is a cost-effective dual-axis voltage output inclinometer with MEMS technology. It has a measuring range of ± 90° and a full-scale accuracy of 0.01° and a operating temperature of -40℃~+85℃. The product has automatic compensation and filtering algorithms to reduce errors caused by environmental changes. It measures the change of static gravitational field and converts it into angle change. The change directly outputs the horizontal angle value through voltage mode. It has high...

BWM 420 Cost-effective Dual-Axis Voltage Output Inclinometer Resolution: The measured minimum change value that the sensor can detect and resolve within the measurement range. Accuracy: The error between the actual angle and the Root mean square(RMS) of the measured angle of the sensor (>16 times). Note: The output voltage and corresponding angle are adjustable. For example, the output variation range is ±15°, corresponding to -15° output voltage 0V, and 15° output voltage 5V (10V). For example, the output variation range is ±137°, corresponding to -137° output voltage 0V, and 137° output...

Cost-effective Dual-Axis Voltage Output Inclinometer Installation direction The correct installation method can avoid measurement error. The following points should be made when installing the sensor: First of all, to ensure that the sensor mounting surface and the measured surface completely close, the measured surface should be as horizontal as possible, can not have the angle shown in Figure A and Figure C, the correct installation is shown in Figure B and Figure D. A B uneven surface generates the angle D uneven surface generates the angle Secondly, the bottom cable of the sensor and...
