Single-axis inclinometer WCA360M

RS-485Modbuscapacitive

Product description
The WCA360M single-axis inclinometer is a compact, low-cost industrial tilt sensor designed for long-term, stable field operation. It uses a capacitive MEMS sensing unit and an anti-interference platform design to provide reliable tilt measurements across a wide temperature range. The device measures tilt without mechanical contact and is fixed directly to the measured object, eliminating the need for a rotating shaft.
