Measuring amplifier for strain gauge sensors

• Universal connection of strain sensors, force sensors and load cell
• Large input range of 1.0 mV/V to 4.0 mV/V
• For cyclic applications with external input for automatic zero point adjustment, suitable for periodic zero adjustment processes (process tare)
• Analogue signal path with fast reaction time

Applications

The amplifiers of X-Sensors are suitable for the universal signal conditioning of strain gauges sensors. They are therefore suitable for amplifying the mV-sensor signal of any force and strain sensors and load cells.

Due to the control input for an automatic zero point adjustment, the amplifier should be used in cyclic applications. Cyclic applications describe recurring, fast force cycles, such as they can be found in presses. Here it is important that a zero point adjustment is made at regular intervals to prevent drifting of the measuring signal.

Zero point adjustment

The zero point adjustment at these amplifiers are carried out by a digital zero adjustment mechanism. The zero point adjustment is not stored permanently, it is lost after a power off. It provides a non-volatile, stable zero point independent of cycle times. Therefore, it is qualified for all dynamic applications and can be used in all kind applications which require a periodical zero point reset, triggered by a digital input.

The reset input does trigger a zero point adjustment by the PLC. It is available with an “Active Low” and “Active High” Logic.
