Description

Overview

The Brüel & Kjær Vibro DS-1053/03/030/010/1 (Bruel & Kjaer DS-1053) is a non-contacting eddy-current displacement sensor from the DS-105x series, with a 2 mm measuring range. The DS-1053 is the reverse-mount version, designed for installation in a sensor holder such as the AC-101. It is used with an OD-105x oscillator (OD-1051 for a 5 m chain, OD-1053 for a 10 m chain) to measure relative shaft vibration and relative shaft displacement.

The order code decodes as: /03 M10 x 1-6g thread, /030 30 mm sensor body length, /010 1 m sensor cable, /1 no cable protection. The sensor has a sealed ceramic tip and a stainless steel body.

B&K Vibro DS-1053 System Compatibility

The DS-1053 does not work on its own. It is one part of a three-part measuring chain made up of the DS-105x sensor, an EC-100x extension cable and an OD-105x oscillator. The oscillator needs -24 V DC (-18 to -30 V), draws up to 16 mA and delivers a -2 to -18 V signal on three terminals.

The chain is tuned to a fixed total cable length: 5 m with the OD-1051 or 10 m with the OD-1053. Sensors calibrated for the 10 m chain carry an extra /3 or /4 at the end of the order code. A 10 m sensor must not be run on an OD-1051, and a 5 m sensor must not be run on an OD-1053, so check the code on the old sensor and the oscillator type before ordering a replacement.

Extension cables are made in 4 m, 4.5 m, 9 m and 9.5 m lengths (EC-1001 plain, EC-1002 with flexible stainless-steel hose, EC-1003 with PTFE tube). They are part of the tuned circuit and must not be shortened or lengthened. The oscillator housing is only IP 20 and has to be mounted electrically insulated inside a protective enclosure.

B&K Vibro DS-1053 Installation and Wiring Notes

The ceramic tip is brittle. Keep the rubber cap on during transport and storage, inspect the tip before every installation and never fit a damaged sensor. The manufacturer calls for about 10 mm of free space around the tip and 40 mm between sensors mounted side by side; the minimum shaft diameter shown is 25 mm for one probe and 40 mm for a pair at 90 degrees. Run sensor and signal cables at least 1 m away from power cables and cross them at right angles. For a quick health check at -24 V supply, a correctly gapped chain gives about -10 V on the signal terminal.

How the Bruel & Kjaer DS-1053 works

The sensor tip carries a coil driven by the oscillator. A metal target near the tip changes the coil signal without contact. The output voltage follows the gap between the tip and the shaft.

About brand

The Brüel & Kjær items on this page are mainly machine vibration monitoring products from Brüel & Kjær Vibro, the company based in Darmstadt, Germany. Its VIBROCONTROL monitors, rack modules and velocity sensors protect turbines, compressors, pumps and fans against damaging vibration.

Seven Star LLC is an independent supplier that sources Brüel & Kjær Vibro monitoring modules, monitors and sensors for plants in Oman and the GCC, mostly as replacements for units already in service.

Brüel & Kjær Vibro product families

The largest group here is rack hardware: SM-610 monitoring modules in many variants (the suffix, as in SM-610-A02 or SM-610-118, fixes the version), the PS-610 power supply module and the CI-620 communication interface. Stand-alone monitors include the VIBROCONTROL 1000, the VC-920 and the VC-868/1, alongside the AMO-622 monitoring system. Sensors include the VS-068 and VS-069 velocity sensors. The manufacturer's present machinery protection platform is the VC-8000. Laboratory accelerometers and sound and vibration analyzers that carry the Brüel & Kjær name are a separate product line, and a few of those instruments are listed here as well; send us the type number if that is what you need.

Where Brüel & Kjær vibration monitoring is used

Typical machines are steam and gas turbines, generators, centrifugal compressors, boiler feed pumps, cooling tower and process fans and gearboxes in power plants, oil and gas facilities, cement works and petrochemical plants. The monitors supply alarm and trip contacts to the plant protection system and measured values to the control room.

Ordering Brüel & Kjær Vibro parts: what we need

Send the complete type designation with its suffix, the order or part number from the label, and the serial number. For monitors add the measuring span, sensor type, supply voltage and output configuration, since many units are configured to order. For sensors give sensitivity, mounting direction, cable length, connector and the hazardous area approval. Photos of the label and of the rack help.

Yes, when used with appropriate intrinsic safety barriers and approved monitoring systems, the DS-1053 is suitable for use in explosive atmospheres common in Oil & Gas sectors.

Does Seven Star LLC provide different cable lengths for this sensor?

The /010/ portion of the part number typically refers to cable length. Seven Star LLC can supply various configurations to meet the specific requirements of your installation site.

Is the DS-1053 compatible with third-party vibration monitors?

While optimized for Bruel & Kjaer Vibro systems, it can often be integrated with other industry-standard proximity transmitters and racks. We recommend a technical compatibility check before installation.
