Product description
RION HCA516T/HCA526T-CAN2.0A is a high-accuracy single-axis inclinometer designed for industrial applications. The unit integrates a high-precision 16-bit differential A/D converter and five-stage filtering algorithms to deliver stable angle measurements relative to horizontal (tilt and pitch). An internal high-precision digital temperature sensor enables temperature-drift compensation; temperature output is optional. The device offers configurable CAN2.0A output and a frequency response up to 100 Hz (higher response customizable). It is built for reliable operation in harsh environments and supports extended industrial use.
