CZ-JQ double shear high precision load cell

 

CZ-JQ double-shear high-precision weighing sensor adopts double shear beam design. The force transmission component is centered by the indenter steel ball. It can automatically reset, adjust the center of gravity, resist lateral force, impact, and multi-layer glue. The sealing is reliable, the surface treatment process is exquisite, and the high-quality cable is used, which can work stably for a long time under severe working conditions. Detailed description of main performance characteristics: ● Heavy-duty load weighing ● Advanced alloy steel components ● High measurement accuracy ● Anti-overload and anti-lateral force technical parameters (can be designed according to user requirements) Technical specifications Unit range 10000 ~ 50000 Kg Sensitivity 2.0 ± 0.02 mV/V Nonlinearity 0.03 ~ 0.1 %FS Repeatability ±0.03 ~ ±0.05 %FS lag 0.03 ~ 0.05 %FS Bridge voltage 12 VDC Input impedance 410±10 Ω Output impedance 350±3 Ω Operating temperature -20 ~ 50 °C Insulation resistance >2000 MΩ/50V Zero temperature drift ±0.02 to ±0.05 %FS/10°C Sensitivity temperature drift ±0.02 to ±0.05 %FS/10°C Allow overload 120 %FS Wiring method Lead connection method see certificate CZ-JQ The double-shear high-precision weighing sensor adopts double shear beam design, and the force transmission component is centered by the indenter steel ball. It can automatically reset, adjust the center of gravity, resist lateral force, impact, multi-layer glue, and reliable sealing. The surface treatment process is exquisite, equipped with high-quality cables, and can work stably for a long time under severe working conditions. It is the most ideal weighing and measuring component for various weighing scales such as electronic truck scale, railway scale, ground balance and ground scale.
