Specifications of 3143D1 triaxial LIVM accelerometer, including physical characteristics, dimensions, connection method, material, performance indicators, environmental characteristics, electrical characteristics
The 3143D1 is a triaxial LIVM accelerometer designed for high‑frequency vibration measurement. It provides four‑pin radially mounted connections, titanium housing, and a hermetic glass‑to‑metal seal for rugged operation.
Mounting is achieved with a 6‑32 mounting screw through a drilled hole, and recommended torque is 10‑15 lb‑in. Recommended cables are Model 6041CXX and Model 6247A2 mounting screw. The device outputs a positive‑going signal proportional to acceleration, with a sensitivity of 100 mV/g and a full‑scale range of ±50 g.
