Range of Sensitivities
Vibetek is available in a range of sensitivities, namely:
Vibetek 3 - Low sensitivity
Vibetek 5 - Low/medium sensitivity, no triboelectric noise
Vibetek 10 - Medium/high sensitivity
(Triboelectric noise is caused by minute amounts of frictional electricity generated by the braid and central conductor of a coaxial cable rubbing against the dielectric.)
Properties
The properties of Vibetek may be summarised as follows:
• Small diameter, only 3.5 mm
• Available in long lengths (hundreds of metres)
• Flexible
• Lightweight, only 19 kg per km
• A sensitivity to suit most applications
• Output signal linearly proportional to strain
• Self screening
• Robust weatherproof jacket
• Definable output, specified by piezoelectric coefficients
• Uniform sensitivity as a function of length
• No pressure ageing
• Uniform sensitivity over a wide temperature range
• Temperature rated -40°C to +65°C continuous
• Good signal to noise ratio
