The LPMS-RS232AL2 includes a SACC-DSI-MS-5CON-PG 9/0.5 SCO, M12 connector for RS232 output. Units supplied with a suitable waterproof cable, User guide card and 1 year warranty. Software: C++ library for windows, Java library for Android, LpmsControl software and Open Motion Analysis Toolkit (OpenMAT) for windows.


The LPMS-RS232AL2 Motion Sensor is a waterproof inertial measurement unit (IMU) and attitude and heading reference system (AHRS) with RS232 connectivity housed in an IP67 Aluminium housing. The unit performs accurate, high speed orientation and displacement measurements in harsh environments. By the use of three different MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer) for drift-free, high-speed orientation data around all three axes is achieved. Integrated temperature and barometric pressure sensors allow accurate altitude measurements. The LPMS-RS232AL2 can be connected to a host system via a 5-pin M12 connection. High data transfer rates allow sampling rates of up to 400Hz. The LPMS-RS232AL2 can be used for both machine and human motion measurements in harsh environments or industrial applications.
