Features: These load cells are particularly stiff, have very good resonance values, and tend to have long life cycles in application. With internal 1000 ohm half bridge strain gauge, the measuring range is 50kg weighing sensor. Half-bridge structure sensor, so you may need to make a combination of these sensors for target weight. Made from premium materials, it is durable in use. It's easy to install and use. Widely used in hopper scales, platform scales, platform balance, belt scales and other electronic weighing devices. This sensor is a group of half bridge strain gauge, using the method can have the following three: 1. Using a sensor with the external resistance to form a full bridge measurement, the range of a sensor range: 50kg. External resistance requirements are higher. 2. The use of two sensors to form a full bridge measurement, measuring the range of two sensors: 50kg * 2=100kg 3. The use of four sensors to form a full bridge measurement, measuring range of four sensors and the range: 50kg * 4 =200kg Specifications: Condition: 100% Brand New Material: Aluminum Alloy Capacity: 50kg/110lb (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*3.5cm/1.38*1.38in Weight: Approx. 21g Package Included: 4 * Weighing Sensors
