Strain gauge amplifiers are used to transform the mV/V output-signals of strain gauges in amplified signals with a higher fault resistance. By the use of an amplifier it is also possible to connect sensors to displays and controlling units with the need for an amplified signal. The model EZE10X006 series are designed for nearly static measurements for example in weighing applications. Cased in a compact housing using the integrated plug connector it can be plugged onto circuit boards. The amplifier is also available with an adapter for top hat mounting.

Application
In combination with force transducers or load cells the amplifier EZE10X006 can be used in industrial weighing. It is possible to connect all kind of strain gauges to the amplifier (up to 1 sensor with a resistance of 350 ohm) with an output signal up to 3,3 mV/V. The internal sensor supply is 10 VDC. Usually the amplifier is not pre-adjusted and the customer connects it to the force transducer and also adjusts it. Because of the 3-wire analogue output of 0/4..20mA (optional 0...10 V) and the needed supply energy for the amplifier between 12 and 24 V it is possbile to connect the model EZE10X006 series directly to PLC. Those normaly come with matching analogue inputs which offer a supply energy of 24 V. The integrated connection strip allows to plug or to braze the amplifier onto a circuit board. An adapterboard with screw-terminals for top hat rail mounting according to DIN EN 50022 in enclosures is available. A dip switch allows to adjust zero point, span and filtering. Although usually there is no accurate adjusted signal needed for PLCs the adaptorboard is also available with potentiometer, which allows accurate signal adjustment. Interfering signals can be damped by a low-pass filter.
