称重传感器,又称为测力传感器和压力传感器,是一种将质量信号转变为可测量的电信号输出的装置,主要有S型、悬臂型、轮辐式、波纹管式、单点式、桥式、柱式等几种样式。称重传感器的工作原理原理上称重传感器就是压力传感器, 只是形状不一样而已。

The PR 6251 range of load cells is specially designed for easy weighing of silos and horizontal tanks. The unique design principle ensures a very compact construction. As a result, existing applications can also be upgraded very easily. The range distinguishes itself above all for its unmatched reliability, robustness and stability, which enable trouble-free operation without adjustment, year after year.

Sartorius PR6251的所有量程都为筒仓和卧式油槽称重测量应用而设计,气无二的设计理念使得PR6251结构紧凑,现有应用更新操作简单。的可靠性、稳健性和稳定性使得传感器年复一年后仍能无障碍操作,无须校准。

 

Special measuring element geometry ensures that the transmission of force into the sensor is always at the optimum level. This minimizes the effect on measurement accuracy whilst a high overload range, high repeatability and good linearity are maintained. There is a particularly wide working temperature range attributable to special resistance strain gauge technology. The hermetically sealed enclosure and special TPE cable allow the unit to be used even under extreme operating conditions in harsh production environments.

PR6251测量元件的特殊几何结构总能确保传感器机身内部力传递处于水准,实现高量程超载对精度影响的最小化,保持良好的重复性与线性。得益于地电阻应变计技术,PR6251的工作温度范围非常广。其全密封外壳和特殊TPE材质电缆线使得传感器能在恶劣操作环境无障碍应用。

 

The entire measurement chain can be calibrated without the use of a reference weight.

A version is also available with a direct output of 4…20 mA. This facilitates easy and cost-effective integration into an existing application. An explosion-proof (Ex) version of this range of load cells is also available, as an option, for use in intrinsically safe environments.

整个量测链无须砝码即可校准,用户可单独购买4-20mA输出模块,并整合到目前即有应用上,简单划算。所有量程都有防爆版本可选。
