AS-062/050/0 B&K Vibro Accelerometer w/MIL-C5015 Connector
Brüel & Kjaer Vibro Accelerometer with MIL-C-5015 Connector
Supported Applications
The AS-062 Series is an acceleration sensor by Brüel & Kjaer Vibro, designed for measuring vibration acceleration on rotating machines. Documented applications include turbines, pumps, and compressors.
Operating Conditions & Performance
The series operates based on the piezoelectric compression principle with an integrated amplifier that converts charge signals into usable voltage signals. The sensor features a stainless steel 1.4301 housing rated IP 66 / IP 67 per EN 60 529 and complies with EMC standard EN 61326-1.
Performance specifications include:
• Sensitivity: 100 mV/g ± 5 % (at 80 Hz / 23±3°C), equivalent to 10,2 mV/m/s² ± 5 %.
• Accuracy of Sensitivity: ± 5 % in the range 4 Hz ... 10 kHz; ±3 dB at 1.5 Hz and 13 kHz; ± 5 % across -50°C ... +120°C.
• Resonant Frequency: > 20 kHz.
• Directional Factor (80 Hz): ≤ 8 ... 10 %.
• Strain Sensitivity: < 0,002 g / (μm/m).
• Magnetic Field Sensitivity: < 80 Hz: 0,001 g/mT; < 1 kHz: 0,014 g/mT.
The sensor supports an operating temperature range of -50 °C ... +125 °C and a storage temperature range (in original packaging) of -20 °C ... +70 °C. Overload capacity is rated for continuous 500 g, with shock resistance up to 5000 g in all directions.
Measurement Ranges
The measurement range varies by supply voltage (Ub):
• ±80 g at Ub = +24 V...+30 V.
• ±40 g at Ub = +20 V.
• ±20 g at Ub = +18 V.
The open-circuit potential is +12,5 V ± 1,5 V across the operating temperature range of -50 °C ... +125 °C. The dynamic internal resistance of the output is ≤ 300 Ω in the working frequency range and approximately 2 kΩ at resonant frequency (with 1 Veff excitation and Ib = 4 mA).
Configuration Options
The AS-062 Series utilizes a constant current power supply of 4 mA (range: 2 mA ... max. 10 mA) with reverse polarity protection, alongside a voltage supply of +24 V DC (+18 V...+30 V), also polarized.
Mounting and Mechanical Interface
The sensor requires a force-fitting, contact-resonance-free, and rigid mounting on the measurement object. The series is delivered with threaded studs for installation:
• M8 x 14
• M8 x 1/4" 28 UNF
Overall dimensions are 48 mm (length) x 25.2 mm (diameter). The sensor mass is approximately 130 g without the cable.
Cable and Electrical Connection
The electrical connection consists of a 2-conductor stranded + shielded cable with ETFE insulation, black outer jacket, and an outside diameter of 3.3 mm (±0.15 mm). The conductor cross-section is 0.14 mm² (7 x 0.16 mm).
Standard connecting cable lengths are typically available in 5 m, 10 m, or 20 m options. A protective conduit for the sensor line is optionally available for 5 m and 10 m cables.
Approvals and Standards
• Protection Class: EN 60 529 (IP 66 / IP 67)
• EMC Compliance: EN 61326-1. Note: Electromagnetic interference per EN 61000-4-3 may influence the measurement value; a grounded steel protective conduit for the sensor line is recommended in such cases.
Key Product Differences
The AS-062 Series is supplied as an acceleration sensor with integrated electronics. The series includes documentation and two specific threaded stud options (M8 x 14 or M8 x 1/4" 28 UNF) to accommodate different mounting requirements.
