VELOMAT传感器SKA-30A系列介绍
力传感器根据横向于纵轴的强度测量原理工作。
SKA-30A 设计用于输送机秤、仓式称重设备、平台秤和高架输送机秤，但也可用于测量施加在机器部件、杠杆、轴等上的力。
该设备被设计为带有测量单元的梁。 由于梁形状和两个 13 毫米尺寸的钻孔，安装该组件时将满足机器制造要求。 通过使用 M12 螺纹来传递力。
应变计的测量元件采用高弹性化合物铸造而成，因此可以防止机械或化学损坏。
应变仪桥测量由于梁上的剪切力而在测量单元中引起的变形。 集成放大器可提供 1 至 9 mA 或 4 至 20 mA 之间的测量信号。 通过使用与应变计电桥并联的电阻器进行校准（软件校准）。
SKA-30A 用于直接连接到自动控制器或控制开关。
The force transducer works according to the strength measuring principle on a transverse basis to the longitudinal axis.
The SKA-30A is designed for application at conveyor scales, bin-type weighing devices, platform scales and overhead conveyor scales, but can also be used for measuring the forces applied on machine parts, levers, axles etc.
The device has been designed as a beam with a measuring cell. Due to the beam shape and two 13 mm size boreholes, all machine building requirements will be met when mounting this component. The force transfer is carried through by use of a M12 screw thread.
The measuring cell for the strain gauge has been cast with a high-elastic compound and is thus protected against mechanical or chemical damages.
The strain gauge bridges measure the caused deformation in the measuring cell due to the shear forces at the beam. An integrated amplifier gives a measuring signal between 1 and 9 mA or between 4 and 20 mA. The calibration is carried out by use of a resistor, parallel connected with a strain gauge bridge (software calibration).
The SKA-30A is assigned for the direct coupling to an automatic control or a controlling switch.
