NM1-2L-420-ATEX Tilt Measuring System

Single axis tilt measuring system

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
