Analogue Strain Gauge Sensor

─ Suitable for relatively heavy item and it is durable. ─

Applying load to Strain Gauge analoge cell affixed metal makes gauge’s resister value change by metal strain. Strain Gauge type sensor measures the change of resister value then converts into weight value. This gives enormous difference in scale performance, such as resolution, stability and repeatability, but dependant on quality of the components used and reflected in the price. OIML versions are used in trade approved applications. 

Digital Tuning Fork sensor

─No trouble with high accuracy and fast response time. ─

Vibration frequency changes against the application of load to two piece coupled Tuning Fork. Scale measures this frequency change then convert to the weight value. Stress-strain of the Tuning Fork is 1/10th and its output sensitivity is 50 times of Strain Gauge Sensors

Digital Electromagnetic Sensor / Hybrid weigh cells.

Electromagnetic force  / Hybrid cellsmeasure the current flown in the coil to determine weight value and convert it to  a digital value . It is suitable for high accuracy (high resolution) measurement.
