bmcm introduces isolated differential amplifiers in miniature format

FROM D. HILLIGES most read

bmcm introduces isolated differential amplifiers in miniature format Maisach/Munich/Germany. The highly compact isolation amplifiers of the MAL-ISO series from BMC Messsysteme GmbH (bmcm) provide a cost-efficient solution for measuring voltage signals or current without interferences.

The importance and necessity to measure with electrical isolation is not obvious to many people, especially since using isolation amplifiers for each channel incurs additional costs.
However, who wants to make reliable statements about measurements, avoid unwanted interferences resulting from earth or ground loops, or separate potentials to protect PC and measurement system, cannot do without galvanic isolation.

This can easily be achieved with the isolation amplifiers MAL-ISO50/10/5/1 from BMC Messsysteme GmbH (bmcm).
They remind of the famous Danish building bricks for children, have the size and form of a 24-pole DIL IC, and in relation to size and pin assignment are compatible to other manufacturers.

The miniature amplifiers vary in measuring range ±50V, ±10V, ±5V, or ±1V). Voltage and current signals (only MAL-ISO1: 20mA) can perfectly be adjusted to the 5V input of a connected data acquisition system.
Especially to mention is the version MAL-ISO50, which, with the introduction of the 42V supply voltage, is particularly interesting for the automotive area.

Common-mode interferences often produced by machinery or other loads in industrial environment are effectively suppressed by the balanced input of the differential amplifier. The measuring signals present what actually is to be recorded.

The isolation modules can be used in any combination and with other measuring converters of the MAL series from bmcm. With this modular conception, an individual measurement system can be set up.

Backplanes (BP series) of different type (e.g. in a water-proof box, as PC slot card) and size (2, 8, or 16 slots) providing for comfortable connection and amplifier supply by the PC data acquisition system.

Measuring amplifiers in miniature format: This is not just true for the extremely compact design but also for the price allowing safe and reliable measurements with electrical isolation.

*** About BMC Messsysteme GmbH (bmcm) ***

BMC Messsysteme GmbH was founded in 1994 as an independent corporation with headquarters in Maisach, app. 30 km west of Munich. bmcm is one of the only German companies that completely develops and produces in Germany. The products of data acquisition and PC technology from BMC Messysteme GmbH stand for quality "made in Germany". A high value is set on keeping an excellent price/performance ratio. Since establishing a direct distribution in July 2006, customers have been able to profit from the advantage of direct contact to the manufacturer.

BMC Messsysteme GmbH serves the following business areas:

* Measuring components and PC measurement technology *
This comprises a wide range of connection systems, measuring amplifiers, data acquisition cards (internal and external), "ready-for-use" data acquisition systems, data loggers and the appropriate software for visualization, recording and analysis.

* PC technology *
This area includes embedded PCs developed as complete solutions as well as single PC components often used in the automotive field.

* D2M (Design to Manufacturing) and OEM products *
BMC Messsysteme GmbH develops and produces electronic components according to customer specifications.

You will receive high-quality products manufactured already since the beginning of 2006 according to the RoHS directive. Of course, the corresponding documentation and CE test is always included.
A German documentation is obligatory for us, as well as an English description to be available to our international customers.
