Measuring device for measuring dynamic behaviors of large structures

The device should ensure the measurements of the dynamic behaviour of large structures: vibration, bending, displacements, deflections and torsion of bridges, masts, chimneys, girders and towers. The system could be based on a laser transmitter and an optoelectronic receiver connected to the object.

RECEIVER

• Power supply: 11 - 30 VDC
• Start-up current: 450 mA (@12V)
• Supply current: < 150 mA (@12V)
• Operating temperature: -20 ... +50*C
• Measuring area diameter: 200 mm
• Nonlinearity (+-70mm) :< +-1 mm
• Resolution: < 0.2 mm
• Beam hit angle range: 90degr +-10degr
• Serial communication: RS 232
• Analog output, 2 ports: +-10V, 10V, 4-20mA
• Max. measuring rate: 500 meas./sec
• Weight: 8 kg (Case 23 kg)
• Dimensions (H W L): 27 / 31 / 32 cm

TRANSMITTER

• Power supply: 10.5 to 15 VDC
• Operating temperature: -20 ... +50* C
• Laser wave length: 670 nm +-10 nm
• Laser class (EN 60825): 2 (Eye safe)
• Laser spot size at 100 m: 10 mm
• Weight 2.0 kg (case 15 kg)
• Dimensions (Max. H W L) 8.4 / 8.4 / 20 cm

The device should ensure obtaining such measurement parameters: vibration amplitude, typical frequencies, static bending, displacemnet direction, direction of the X/Y movement in horizontal level.
