Weight Sensor (Load cell) 50kg

Overview

This 50kg weight sensor (load cell) is a fundamental component for any electronics project that requires accurate weight, force, or pressure measurement. It is a straight bar load cell that converts force into a measurable electrical signal, making it ideal for building digital scales, force gauges, and industrial automation systems. With a rated capacity of 50kg, it balances sensitivity and robustness, making it a versatile choice for both hobbyist and professional applications.

Key Features

• High Accuracy: Nonlinearity of 0.08% F.S. and repeatability of 0.05% F.S. ensure reliable measurements.
• Robust Construction: Designed to withstand up to 50kg load with a safe margin for typical applications.
• Standard Output: Rated output of 1.0 ± 0.1 mV/V, compatible with most load cell amplifiers and ADCs.
• Wide Operating Temperature: Works from -20°C to 65°C, suitable for most indoor and outdoor environments.
• Low Zero Balance: Zero balance of ±0.1000 mV/V ensures minimal offset for accurate readings.
