ACA6 HIGH ACCURACY DIGITAL TYPE MODBUS TILT SENSOR WITH FULL TEMP-COMPENSATION
ACA6 HIGH ACCURACY DIGITAL TYPE MODBUS TILT SENSOR WITH FULL TEMP-COMPENSATION
Optimized English Introduction:
ACA616T/ACA626T is a high-precision, full-temperature-compensated single/dual-axis tilt sensor with MODBUS digital output, developed by RION Technology based on an advanced precision tilt platform. Featuring excellent temperature stability, it operates reliably in wide temperature ranges from -40℃ to 85℃, making it ideal for long-term outdoor equipment monitoring and leveling.
Key Features:
-
Built-in high-precision 24-bit differential A/D converter;
-
Fifth-order filtering algorithm ensures precise measurement of tilt and pitch angles relative to horizontal;
-
Available with RS485, RS232, or TTL output interfaces for flexible system integration;
-
Non-contact installation design—simply mount the sensor on the object's surface with screws, no alignment required;
-
Strong resistance to electromagnetic interference, shock, and vibration;
-
Offers a significant competitive edge among domestic peers, tailored for high-end industrial applications.

▶ WORKING PRINCIPLE
Adopt imported core control unit and apply the principle of capacitive micro-pendulum. Using the principle of earth's gravity, when the tilting unit tilts, the earth's gravity will produce a gravitational component on the corresponding pendulum, and the corresponding electric capacity will change. By amplifying and filtering the electric capacity, the inclination is obtained after conversion.
