The SLB700A/06VA is an active strain sensor fitted with smart electronics, which has been proven for many years in measurements concerning the force shunt. Standard output signals include 0 ... 10 V or 4 ... 20 mA. Its main application fields include basic weighing tasks, such as tank weighing and measurement in production, including press monitoring.

SLB700A/06VA Active Strain Transducer: A Cost-effective Sensor with Integrated Electronics for Extremely High Forces
The SLB700A/06VA is a strain transducer with integrated electronics, which can easily be attached to structures with screws. If force is applied to the structure, the SLB700A/06VA reliably measures the resulting strain. Since the strain is often proportional to the force, the strain sensor can be used to measure the applied force, provided a corresponding calibration has been made. This principle is also called ‘measurement in the force shunt’.
The SLB700A/06VA active strain transducer is simply as robust as the passive version, that is, the SLB700A. However, the active SLB700A/06VA is more cost-effective, owing to its integrated measuring amplifier. The advantage of this attractively priced sensor is that it enables even extremely large forces to be measured in a reliable manner. The machine dynamics remain unaffected.
The teach-in procedure for the electronics utilized in the SLB700A/06VA is very simple. It only requires a measurement to be taken at the maximum force and another measurement at zero force. The output signal is scaled between these two points; irrespective of the strain level, the maximum possible signal will be transmitted to the next level in the measurement chain (refer to the explanation provided below).
The sensor materials withstand most of the oils used in applications involving presses and are rustproof.
Proven for years in production environments: Easy retrofitting of machines is possible due to the full compatibility of active and passive strain sensors.
Extremely cost-effective; enables extremely large forces to be measured, even on a tight budget. No additional electronics are required. An optimal resolution is guaranteed due to the teach-in procedure.

A diferencia de nuestro producto, es decir, el SLB700A/06VA, otros sensores de medición de deformación disponibles con un módulo amplificador integrado solo tienen una amplificación fija. Así, por ejemplo, 500 µm/m corresponden siempre a una salida de 10 V. El principal inconveniente de este método es que la señal de salida máxima está vinculada a la amplificación de origen, que no puede cambiarse. Si, en el ejemplo anterior, la señal de entrada es de 200 µm/m, la tensión de salida resultante sería de tan solo 4 V. Esto puede hacer que los resultados sean insatisfactorios, en especial si el siguiente elemento de la cadena de medida es un módulo con baja resolución o alto nivel de ruido (por ejemplo, si es un aparato económico).
Los extensómetros SLB700A/06VA de HBM, con su electrónica de amplificador integrada, resuelven este problema porque son capaces de proporcionar la máxima señal de salida posible en cualquier momento, con independencia de la situación.
Para ello, HBM ha desarrollado un procedimiento “teach-in” muy sencillo .
