The Modal Shop Introduces the SmartShaker
The Modal Shop, A PCB Group Company, announces the SmartShaker(TM), a revolutionary innovation in electro-dynamic excitation. The models K2004E01 and K2007E01 are four and seven pound force exciters, respectively, that eliminate the bulk, weight and aggravation of the traditional companion 19 inch rack-mount power amplifiers by integrating solid state power amplifier electronics inside the shaker package. What formerly required over 800 cubic inches of rack space, commonly weighing dozens of pounds, now fits compactly in a 3 x 3 x 0.75 in (7.5 x 7.5 x 1 cm) footprint beneath the shaker. This Integrated Power Amplifier design concept follows the PCB® Piezotronics tradition of simplifying the test and measurement process by integrating the needed electronics, much like the original ICP® accelerometers miniaturized and moved the "charge amplifier" to inside the sensor package. The small overall size (3.6 x 3.5 x 5.3 in (9.1 x 8.9 x 13.5 cm)), weighing just 7 lbs, makes it a new class of portable solution for university test laboratories and benchtop vibration studies. Powered via a small DC power supply, similar to those supplied with your laptop, the SmartShaker can be run directly from any 12-21 VDC supply, making it an ideal companion to today's portable PC based data acquisition market.
The SmartShaker models provide up to 7 pounds pk sine force with a ½ inch stroke covering a broad frequency range up to 11 kHz. They feature extremely rugged suspension systems using carbon fiber composite leaf armature flexures, avoiding the suspension damage common to other mini shakers. Intelligent innovations in the SmartShaker with its integrated power amplifier include: 92% ultra-efficient operation for low power consumption, multiple gain settings and system "mute" selectable via integrated digital control and Smart monitoring of amplifier clipping, overcurrent or overheating with automatic shutdown. Ergonomic EasyTurn(TM) handles and a variety of nylon stingers provide for safe and simple shaker / trunnion positioning.
The SmartShaker(TM) models are the latest members of the full line of electrodynamic exciters and SmartAmplifiers(TM) from The Modal Shop. Each shaker in the line is delivered as a complete kit with all the needed accessories, trunnion mounting base, cable and a variety of complimentary stinger kits for easy attachment to test articles. Stock product for quick delivery and the Total Customer Satisfaction Guarantee have gained TMS the reputation as the fastest growing manufacturer in the portable shaker market.
