The SEIKA SBG3I is a three-axis tilt/acceleration measurement sensor box housed in a die-cast aluminum enclosure with IP67 protection. It integrates three SEIKA sensors and three independent 4–20mA current standardization amplifiers with electrical isolation between channels.
Equipped with temperature error compensation, EMC protection, and low-pass filtering for anti-interference, it operates at 10–30V DC and outputs 4–20mA signals. It allows custom measurement direction and zero-point adjustment, features high overload and vibration resistance, and reliably works in temperatures from -40℃ to +85℃, making it ideal for harsh environments such as construction, mining, marine, and industrial automation.
