Single Vibrator Systems

VTS designs and manufactures Electrodynamic Vibration Testing Systems from 40 to 600 pounds force for modal testing, research and development, product qualification, vibration screening and vibration demonstration.

Single Vibrator Systems / 40 To 150 Pounds Peak Sine Force

VTS offers five low cost systems in the 40 lbf to 150 lbf range. The vibrators from 40 lbf to 100 lbf peak sine force have permanent magnet fields. The 150 lbf peak sine force has field coils and also is supplied with a DC power supply. Their conservative rugged design offers trouble free operation.

Systems include:

Vibrator with trunnion base
Low-distortion linear amplifier
Fan amplifier cooling in VTS 40, 65, 80, 100 and 150 lbf systems
Cables and hoses where required

Low-Noise B-1 Blower
The B-1 Blower incorporates a sound absorption system to reduce its noise level to less than 70 dBA. The rugged Blower enclosureis equipped with an 8 ft. flexible hose, a 10 ft. power cord, and a two speed on/off switch.
