About the NM1-2L-420-ATEX Tilt Measuring System

The single axis industrial tilt measuring system NM1-2L-420-ATEX is the combination of a non-contact inclination sensor and sensor adapted electronics. The measuring system is designed for precise tilt measurement in one axis. It is applicably for the use in defined explosion hazardous areas according to the attached EU type examination certificate. The system is intended for side assembly. Available tilt measuring ranges are ±3° to ±60° or 0 … 10° to 0 … 90°. The analogue output signal of 4 ... 20mA in 2-wire-technology is a standard signal and therefore a further analysis is easily feasible.

The tilt measuring system is built into a robust EMC-safe die-cast aluminium enclosure with external mounting holes (IP68, test condition 1h, 1m water depth), which is well suited for applications in rough and industrial environments. Furthermore, the built-in electronics are protected against humidity and vibrations.
