Key Features & Benefits of the Parallelogram Load Cell LSM305
Integrated Smart Sensing – Equipped with IEEE-1451.4 TEDS auto-recognition and onboard PT1000 RTD temperature sensor, enabling automatic calibration and real-time temperature compensation.
Robust Overload Protection – Built-in stops protect in both tension and compression, allowing the unit to survive loads beyond its rated range.
Exceptional Performance – Nonlinearity and hysteresis as low as ±0.02% of rated output (for 2.2–100 lb models), with strong repeatability and low creep.
Compact & Lightweight – The sensor weighs around 28 g for lower capacity models, making it ideal for tight, weight-sensitive systems.
Flexible Output & Interfaces – Compatible with analog (mV/V), VDC, mA, SPI, RS-422, USB, BLE, RS-232, UART, and more, making it adaptable to varied system architectures.
OEM & Embedded Ready – Designed for high-volume integration, side mounting, quick connector deployment, and easy replacement in the field.
