Current Measurement

Solutions

For measurements of smaller currents in the range of 0 ... 20mA measuring amplifiers and measurement systems by BMC Messsysteme GmbH are the perfect solution. Please note that it is a great advantage to use e.g. the measuring amplifiers MA-UI or the miniature measuring amplifiers of the MAL-ISO-Series for the galvanic separartion of signals to the measuring.

With the miniature measurement amplifiers of the MAL-Series it is very easy to connect your sensors to the measurement systems of BMC Messsysteme GmbH. With our 5B compatible measurement amplifiers these signals can even be galvanically isolated from the measurement system.

Currents are often captured in two different contexts. For one the power input of a device can be ascertained with both signals current and voltage. In this case it is common to examine current peaks that are caused by faults, respectively the continuous current consumption. The usual value lies between 1A ... 100A in most currents. Another case of application is the transmission of process signals via current. Common are 0 ... 20mA, respectively 4 ... 20mA. The signal transmission of currents has the advantage that a voltage drop does not affect the quality of the signal.

The common "sensor" for the acquisition of smaller currents is a shunt. This is a highly precise resistence through which the voltage drop is measured. Current measurement is tranferred into a voltage measurement. The disadvantage is the partly unwanted voltage drop in the current-shunt and the dependence on temperature. For high currents a galvanic separation of the current is applicable. These are based on the physical principle of the hall effect.
