SP4M - Maximum accuracy single point load cell: available in C6 quality

The SP4M single point load cells are now available as the successors to the successful SP4 series for maximum capacities from 1 kg up to 200 kg. The major innovation: The load cells now also offer C6 quality and thereforemaximum measurement accuracy. However, a lot has been done with regard to the C3 quality models too: A broad choice of options ensures maximum flexibility.

Advantages of C6 quality:

'C6' denominates a load cell's accuracy with regard to its error limits (mpe) according to the OIML R60 international recommendation. It is the highest measurement accuracy that can currently be attained in strain-gage technology based mass-production. Load cells with C6 accuracy enable legal-for-trade scales with a permissible number of 6000 verification intervals to be produced. There are two direct advantages:

  • In applications where you previously had to use several scales with different weighing ranges, a single scale in C6 quality is now sufficient. For example: While, for example, a scale with a weighing range of 15 kg and 5 g verification intervals was required and, in addition, a scale with 30 kg/10 g, it will now be sufficient to use a single scale with 30 kg/5 g that even works without verification interval changeover. This saves costs when purchasing and performing the statutory verification required every two years.

  • C6 quality proves its superiority also in fields of applications that are not subject to statutory verification: Particularly with temperature changes, these load cells offer considerably higher accuracy and therefore more reliable test results.

Precix series offers tested C6 quality
 

Many manufacturers promise load cells with C6 accuracy. With HBM you can trust in real and reliable C6 quality. This has been proven in many tests: The precix series comprising all HBM load cells in C6 quality ensures extremely precise test results. Linearity, hysteresis, dead load output return, and all other parameters required for a legal-for-trade load cell invariably have ideal values. HBM's labels live up to their promises: C6 quality on the label means C6 quality inside.
 

C6 quality is available for SP4M series load cells with the following maximum capacities: 7kg, 10kg, 15kg, 18kg and 36kg and, optionally, also 20kg and 30kg.

Maximum flexibility thanks to many options

Few single point load cells offer absolute measurement accuracy like this combined with so many options that enable use in numerous applications. By default, the models from this series are delivered with a 3 m long, shielded, robust 6-wire connection cable. They offer IP67 protection and have been designed for assembling multi-interval weighing machines. With models in C3 quality, the modular principle enables users to custom-assemble load cells for their special needs.

Select:

  • the size that suits your requirements from 13 different maximum capacities (from 1 kg up to 200 kg),

  • from four different cable lengths (1.5m, 3m, 6m or 12m),

  • whether you need an ATEX version complying with European Directive 94/9/EG (ATEX95) to enable your load cell to be reliably used in potentially explosive atmospheres,

  • whether you need an aligned output for connecting several load cells in parallel, for example, when assembling weighing systems with large platforms.

The excellent price-to-performance ratio of the models from this load cell series for universal use makes them the perfect choice.

Special features:

  • Accuracy class C3MR and C6MR with OIML-R60 test report

  • Off center load compensated (OIML R 76)

  • Degree of protection IP67 (according to EN 60 529)

  • Shielded connection cable

  • Suitable for multi range applications

Optional:

  • Explosion proof versions

  • Different cable lenghts

  • Aligned output, suitable for connection in parallel

传感器小知识之电阻应变式称重传感器原理:
电阻应变式称重传感器是基于这样一个原理:弹性体(弹性元件,敏感梁)在外力作用下产生弹性变形,使粘贴在他表面的电阻应变片(转换元件)也随同产生变形,电阻应变片变形后,它的阻值将发生变化(增大或减小),再经相应的测量电路把这一电阻变化转换为电信号(电压或电流),从而完成了将外力变换为电信号的过程。 由此可见,电阻应变片、弹性体和检测电路是电阻应变式称重传感器中不可缺少的几个主要部分。弹性体是一个有特殊形状的结构件。它的功能有两个,首先是它承受称重传感器所受的外力,对外力产生反作用力,达到相对静平衡;其次,它要产生一个高品质的应变场(区),使粘贴在此区的电阻应变片比较理想的完成应变棗电信号的转换任务。
