- 2-wire technology
- In a rugged die-cast aluminum housing (IP68)
- Suitable for use in hazardous areas
About the NM1‑2L‑420‑ATEX Tilt Measurement System
The NM1‑2L‑420‑ATEX is an industrial, single-axis tilt measurement system specifically designed for use in explosive environments. With ATEX certification (TÜV 99 ATEX 1469 / II 2G Ex ib IIB T4 Gb), it meets strict safety requirements for hazardous areas.
The system combines a contactless tilt sensor with matched electronics to provide precise single-axis tilt angle measurements. It is designed for sidewall mounting and is ideal for harsh industrial applications.
Thanks to a 4 … 20 mA analog output in 2-wire technology, measured values can be easily integrated into standard control and evaluation units.
The robust, EMC-protected aluminum die-cast housing with IP68 protection (1 h at 1 m water depth) ensures reliable operation even in humid, dusty, or vibration-intensive environments.
Technical Highlights
- Selectable measurement range: ±3° to ±60° or 0 … 90°
- High measurement accuracy, e.g., ±0.1° up to ±10°, ±0.2° up to ±30°, ±0.25° up to ±60°
- 2-wire analog output 4 … 20 mA
- Supply voltage: 18 … 28 V DC, reverse polarity protected
- Frequency response: 0.5 Hz
- Low cross-axis sensitivity < 1.5 %
- Operating temperature range: −25 … +60 °C
- Weight approx. 800 g (with 10 m connection cable)
Applications
The NM1‑2L‑420‑ATEX is suitable for precise tilt measurements in explosive industrial environments, such as:
- Machinery and plant monitoring
- Offshore and energy installations
- Mining and process industry
- Conveyor and lifting systems
- Safety technology and automation
