Features: These load cells are particularly rigid, have very good resonance values, and tend to have long life cycles in applications. With internal 1000 ohm half-bridge strain gauge, the measuring range is 50 kg weighing sensor. Half-bridge structure sensor, so you may need to make a combination of these sensors for target weight. Made of premium material, it is durable in use. It is simple to install and use. Widely used in container scales, platform scales, platform balances, belt scales, and other electronic weighing devices. This sensor is a group of half-bridge strain gauges, using the method can have the following three: 1. Using one sensor with the external resistance to form a full bridge measurement, the range of one sensor range: 50 kg. External resistance requirements are higher. 2. The use of two sensors to form a full bridge measurement, measuring the range of two sensors: 50 kg * 2 = 100 kg 3. The use of four sensors to form a full bridge measurement, measuring the range of four sensors and the range: 50 kg * 4 = 200 kg Specifications: Condition: 100% Brand New Material: Aluminum Alloy Capacity: 50 kg/110 lb (each) Structure: Half Bridge Interior: 1000 Ohm Half Bridge Strain Gauge Wire Connection: Red for positive pole, black for negative pole, white for data output Size: Approx. 3.5 * 3.5 cm / 1.38 * 1.38 inches Weight: Approx. 21g Package includes: 4 * Weighing Sensors
