Technical Overview

The Brüel & Kjær Vibro SD-081/3/075/10/0/0/169 is a member of the SD-08x family of eddy-current displacement sensors, used for continuous non-contact measurement of radial shaft vibration and axial position on rotating machinery. Per the manufacturer’s shared SD-08x family datasheet (SD08xdef.pdf), sensors in this series provide a confirmed linear measuring range of 1.2 to 4.7 mm, a frequency response from 0 to 10,000 Hz, and an operating temperature range of −30°C to +180°C at the probe tip, making the family suitable for demanding high-temperature bearing housing locations found on steam turbines and process compressors. The SD-08x sensors are designed to comply with API 670 and DIN 45670 standards for machinery protection instrumentation, and are used in conjunction with a matched oscillator-demodulator unit — typically an OD-081 or OD-083 — which converts the probe’s raw electromagnetic gap signal into a linear, temperature-compensated DC voltage output for use by a monitoring system such as VIBROCONTROL or VC-6000.

The long order-code suffix on this specific part number (/3/075/10/0/0/169) encodes configuration details such as cable length, connector style, and mounting thread specific to the exact unit ordered, consistent with how Brüel & Kjær Vibro structures its eddy-current sensor part numbers across the SD-08x range. Seven Star LLC’s research confirmed the family-level specifications above from the manufacturer’s official shared datasheet, but the precise meaning of each individual segment in this particular trailing suffix was not independently confirmed from a directly accessible ordering table; a probable inference is that the segments correspond to cable length and connector/thread configuration, consistent with the general SD-08x ordering-code structure, but Seven Star LLC states this explicitly as an inference rather than a confirmed fact. Customers should provide the full existing part number when ordering so this can be cross-checked against the manufacturer’s complete ordering guide before shipment.

Applications

SD-08x family sensors are installed on radial and axial bearings of critical turbomachinery — steam turbines, gas turbines, centrifugal compressors, and large pumps — where continuous API 670-compliant vibration and position monitoring is required. The extended high-temperature rating of this family makes it particularly suited to bearing locations close to hot process equipment or turbine casings, where standard-temperature sensors would be unsuitable.

Why Seven Star LLC

Ordering the correct eddy-current sensor variant for a specific machine train requires matching the exact probe length, range, temperature rating, and connector configuration to the existing installation or new design specification. Seven Star LLC works directly with customers across Oman and the GCC to confirm every element of the ordering code — including any suffix segments not fully documented in publicly accessible manufacturer literature — against Brüel & Kjær Vibro’s complete records before finalizing a quotation, so the delivered sensor matches the customer’s application without costly reordering delays.
