Brüel & Kjær Vibro Releases World’s First Fully Integrated, Loop-powered Displacement Transmitter

In order to fulfill the need for economical displacement transmitters with simplified installation, Brüel & Kjær Vibro (B&K Vibro) announces the release of the DT-12x series of transmitters. These fully integrated, loop-powered displacement transmitters offer a unique streamlined solution for shaft displacement and vibration monitoring capability for a wide range of industrial machines.

The DT-12x series are fully integrated transmitters which means the driver (oscillator) and signal conditioning electronics (vibration monitor) are built directly into the sensor. This greatly simplifies installation by eliminating the need and space requirements for a driver, vibration monitor and eventually a protective housing. Due to this innovative design the transmitter can directly be connected to a DCS or PLC using it’s standardized 4-20 mA output. The transmitter is loop-powered, so its 4-20 mA signal is not affected by long wiring distances, voltage drops or noise. This greatly simplifies installation even more when connecting to a DCS or PLC, since only two wires have to be connected in the current loop.

The DT-12x series displacements transmitters are also very versatile from a monitoring perspective. In addition to the 4-20 mA outputs, there are also buffered output wires for transferring voltage signals to portable monitoring instruments for analysis and data storage. The transmitters are also built for harsh industrial environments.

We made a strategic decision to reduce the number of components in the displacement transmitter measurement chain and reduce the overall installation and operational costs, but still maintain a high level of precision and quality.” says Florian Endres, Sensor Product Manager at B&K Vibro. “DT-12x was the answer. I believe it was actually the world’s first such development, but it wasn’t such a technological hurdle. We have already gained considerable experience over the years with integrated sensor technology in our IN-08x series of displacement sensors.

The DT-12x series of displacement transmitters are available in three different mounting configurations, as described on the B&K Vibro website (www.bkvibro.com).
