Signal amplifier 9236

currentvoltagemeasuring

Situations often occur in practice in which it is necessary to place a measuring amplifier immediately in the neighborhood of the sensor in order to be able to access a standard signal there. In this way, long distances to the evaluating electronics can be covered. This task can ideally be performed by the 9236 in-line measuring amplifier. With its high degree of protection (IP67) its singlechannel version can be integrated into the application even in the tough environment outside the switch gear cabinet. In the multichannel version, up to four measuring channels can be implemented in one housing for the DIN carrier rail. This means that it can be located either in the switch gear cabinet, or in the immediate neighborhood of the sensor. Users who want to put the amplifier onto an existing circuit board or who wish to construct their own housing can also obtain the amplifier as an open circuit board. It can be integrated by means of screw terminals. The 9236 measuring amplifier finds applications wherever the output signal from sensors based on wire strain gages, such as force, pressure or torque sensors, must be converted into a voltage signal, e.g. - Automatic production machinery - Laboratory measurements - Integration into customer‘s circuit boards - Field measurements The measuring amplifier itself is powered by voltages between 15 V and 30 V. Internally, the highly accurate, short-circuit protected sensor excitation voltage is generated and used to supply the sensor‘s measuring bridge. The input range of the amplifier is appropriate for sensitivities between 0.5 and 30 mV/V and is also suitable for semiconductor strain gages.
