Single-axis inclinometer SWR34X

dual-axisXYdigital

Product Overview
The SWR34X (single‑axis) and SWR34D (dual‑axis) are digital inclinometer/tilt switches designed for horizontal safety alarming and platform leveling detection. They feature built‑in relay outputs with passive relay contacts (1A drive) and user‑configurable tilt alarm thresholds via RS232. When the tilt exceeds the configured limit, the relay contact signals can directly control hydraulic solenoid valves for outrigger leveling. The devices incorporate temperature and linearity compensation and provide protection against short circuits, surges, reverse polarity and transient overvoltages. Constructed with industrial‑grade MCUs, conformal‑coated PCBs, imported shielded cables and wide‑temperature metal housings, they are suitable for harsh industrial environments.
