Overview

The inclinometers of the ACA series are designed for inclination measurement in harsh environments, on one or two axes, with very high precision.

High precision and thermal stability: Equipped with a 24-bit A/D converter and an advanced filtering algorithm, the ACA series features temperature compensation ensuring excellent stability and repeatability, even in extreme conditions.

Multiple output options: Analog and digital interfaces available (RS485, RS232, Modbus, CANopen) for easy integration and reliable data transmission.

Robustness and sealing: Stainless steel design with excellent corrosion resistance. Equipped with seals, the structure achieves a protection level up to IP68, allowing use in harsh environments, including submersion up to 50 m.

Installation

The ACA series inclinometers are mounted on the surface of the object or structure to be monitored using 4 M4 screws. The inclinometer is powered by 12-36 VDC. The connector is of the M12 type. Installation can be carried out on various supports, making the ACA616T/ACA626T suitable for diverse environments, including those subject to vibrations or harsh conditions.
