About the NM1‑ISU‑IP Tilt Measurement System

The NM1‑ISU‑IP is an industrial, single-axis tilt measurement system for precise detection of inclination angles in demanding environments. It is specifically designed for sidewall mounting and provides reliable monitoring of tilt changes along the X-axis.

The system combines a contactless tilt sensor with advanced electronics for accurate measurement data. Tilt ranges can be flexibly set via an internal DIP switch – including ranges from ±10° to ±180°, depending on the version.

Measured values are output via a serial RS232 interface. Optional variants also provide a scalable analog output (4 … 20 mA) for easy integration into common control and automation systems.

The measurement system is housed in a robust, EMC-protected aluminum die-cast enclosure with IP66 protection, resistant to mechanical stress, dust, and moisture – ideal for harsh industrial environments.

Technical Highlights

  • Single-axis tilt measurement along the X-axis
  • Adjustable tilt ranges via DIP switch (e.g., ±10° to ±180°)
  • High accuracy: ±0.2° under standard conditions
  • RS232 interface for digital output
  • Optional analog output (4 … 20 mA)
  • Supply voltage: 22 … 26 V DC with reverse polarity protection
  • Measurement frequency: approx. 0.4 Hz
  • Repeatability / hysteresis: ±0.1°
  • Operating temperature: –20 °C to +60 °C
  • Robust IP66 enclosure, EMC-protected aluminum

Typical Applications

The NM1‑ISU‑IP is ideal for:

  • Machine and plant positioning
  • Component alignment and tilt monitoring
  • Automation and control systems
  • Industrial process and manufacturing environments
  • Measurement tasks with variable tilt ranges

The NM1‑ISU‑IP offers flexible tilt ranges, a digital RS232 interface, and an optional 4 … 20 mA analog output, making it highly versatile. Its robust construction and high measurement stability ensure reliable results even in harsh conditions – ideal for demanding industrial and automation applications.
