SLB700A/06VA 有源应变传感器：内置电子元件的高性价比传感器，适用于极大的力

SLB700A/06VA是一款内置电子元件的应变传感器，可以轻松地通过螺钉连接到结构上。在对结构施加负载时，SLB700A/06VA可以可靠地测量产生的应变。由于应变通常与力成比例，因此应变传感器可用于测量施加的力，前提是已进行相应的校准。这个原理也被称为“力分流测量”。

SLB700A/06VA 有源应变传感器与无源版本，即 SLB 700 A 一样结实可靠。然而，有源SLB 700 A/06 VA由于其集成的测量放大器而更具成本效益。这款极具性价比的传感器的优势在于，它能够以可靠的方式测量非常大的力。机械结构动力学性能不受影响。

SLB700A/06VA 中使用的电子设备的示教程序非常简单。它只需要在最大力下进行一次测量，在无负载下进行另一次测量。输出信号在这两个点之间缩放，无论应变水平如何，最大可能的信号都将传输到测量链中的下一级（请参阅下面提供的解释）。

传感器材料可承受压机应用中使用的大多数油的侵蚀，并且是防锈的。

Fast sensor teach-in. This is how it’s done:

Unlike our product, that is, the SLB700A/06VA, other available strain sensors with an integrated amplifier module only have a fixed amplification. For instance, 500 µm/m correspond to an output signal of 10 V. The fundamental drawback of this method is that the maximum output signal depends upon the given amplification, which cannot be changed. If, in the example above, a strain of 200 µm/m is utilized as the input signal, the resulting output voltage is 4 V. Particularly, when the next element in the measurement chain is a module that has a low resolution or increased noise (i.e., when economic aspects are of paramount importance), the results often are unsatisfactory.

SLB700A/06VA strain sensors from HBM, with integrated amplifier electronics, manage to bypass this problem, since they provide the maximum possible output signal at any time, independent of the intended purpose.

In order to achieve this, HBM has developed an extremely simple “teach-in procedure”.

First, the sensor is installed in the usual manner, and the load on the machine (press, roll stand, silo) is reduced to zero. A longer pulse sent to the teach-in input is sufficient for the electronics to memorize the zero point.
Subsequently, the maximum load is applied, sending another (this time, a SHORT one) pulse to the teach-in input is sufficient. Now, the electronics is adjusted between these two points.
This enables the input range of the next level to be fully utilized at any time.

Further advantages:

There is always a buffer of 10% in the upper and lower parts of the measuring range. Higher strain signals (e.g. in the event of a failure) are amplified and transmitted.
The characteristic curve can also be negative. Both elongation and shortening can be converted into a positive signal.
The built-in measuring amplifier provides low noise and a bandwidth of 2 kHz.
It is essential to permanently store the span, i.e., the difference between the minimum and the maximum. Therefore, it is imperative to reset to zero after a power failure.
