2-Axis Compact Inclination Sensor Module – Model: DWL-4200XY

Digi-Pas® DWL-4200XY is a 2-Axis Precision Inclination Sensor Module of accuracy (0.01° or 175µm/M or 36 arcsec) that specifically designed to be integrated into a machine/equipment/structure for real-time simultaneous monitoring of leveling status & vibration measurement. These intelligent inclination sensor modules are embedded with advanced MEMS technology sensor, developed for 2D planar leveling, tilt angle monitoring, alignment and vibration measurement.

Inclination sensor modules are tough, durable, waterproof, shock resistance, small footprint and enabled to communicate through various protocols such as USB, RS232, RS485 & Wireless Bluetooth.

    Precision levelling and tilt angles measurement essentially involve simultaneous 2-dimensional planes rather than conventionally known as two independent single-axis. Digi-Pas® 2-axis intelligent inclination modules having high precision and wide measurement range are capable of providing real-time levelling, angular & vibration readings that empower application engineers to continuously measure and monitor machine/equipment/structure angular positional status precisely and speedily.

    These small footprint, 2-axis and high shock resistant MEMS driven inclination sensor modules effectively eliminate limitations associated with using multiple single-axis sensors or bulky pendulum/servo-based sensors to achieve precise 2D levelling and planar angular measurements. MEMS sensor contents no moving part, essentially requires little/no maintanance when compared to pendulum-based sensor.


    Digi-Pas® 2-axis precision inclination sensor module system is designed to be integrated into precision machine/equipment/structure enabling application engineers to instantly access angular positional status without the need for tedious and time-consuming programming.

    The angular measurement system enables user-defined settings to activate any external connected peripheral devices at ease.


    DWL-4200XY Series Inclination Sensor Modules accuracy is verified by accredited 3rd party independent calibration & test bodies and National Metrology Centre traceable to SI standard and NIST, JIS, UKAS & DIN under CIPM MRA.
