Single-axis tilt sensor NTS3

digitalRS-485RS-232

Product introduction
The NTS3 series tilt sensor is a compact digital-output MEMS tilt sensor designed for static and slowly changing dynamic angle measurement in industrial environments. It integrates a dual-channel gravity measurement unit to convert gravitational acceleration into roll and pitch angles relative to the horizontal plane. Output interfaces are selectable: RS232, RS485 or TTL. An onboard MCU performs secondary linearity correction to improve output accuracy compared with basic analog sensors. The sensor uses a non-contact measurement principle, provides real-time attitude output, is easy to install and does not require repositioning opposing surfaces.

Key features
