Product Description

BWM427 Cost-Effective Modbus Dual Axis Inclinometer RS232/RS485/TTL Optional 




BWM427 is a cost-effective dual axis inclination sensor with MEMS technology and digital output. It converts the change of static gravity field into inclination change, and directly outputs the horizontal inclination value through digital mode, with the highest accuracy of 0.01 °. This product has small temperature drift, high long-term stability and simple use. It is an excellent choice for engineering machinery, surveying and mapping, medical and other industries!
