The Modal Shop, A PCB Group Company

What The Modal Shop, A PCB Group Company does

The Modal Shop, Inc. is a Cincinnati, Ohio-based engineering company that designs, manufactures, and supports structural vibration and acoustic sensing equipment for design and test laboratories, manufacturing plants, and industrial hygiene applications. Its portfolio spans three core product pillars: precision calibration systems (accelerometer, microphone, and dynamic pressure sensor workstations, plus factory recalibration services and an interlaboratory comparison program), digital sensing products (the Digiducer USB digital accelerometer family, the Model 485B39 USB signal conditioner, and a digital vibration meter kit), and modal and vibration test shakers ranging from 2 lbf to 500 lbf with accessories for CubeSat and horizontal-table testing. The company also operates an extensive sound and vibration rental program that ships calibrated sensors, complete measurement systems, calibration equipment, noise monitoring systems, and structural test products on daily, weekly, monthly, or custom terms across the US, Canada, Mexico, and international markets, plus a Resonant Acoustic Method (RAM) non-destructive testing product line for 100% inspection of metal components.

Underlying technology is built on PCB Piezotronics' proprietary piezoelectric sensing stack — including the registered ICP (Integrated Circuit Piezoelectric) trademark — augmented by air-bearing shaker calibration methodology that delivers materially lower measurement uncertainty than flexure-based competitors. The Modal Shop is a wholly owned subsidiary of PCB Piezotronics, Inc., which is itself a wholly owned subsidiary of Amphenol Corporation, operating within the Amphenol Sensors division alongside sister companies Endevco, IMI Sensors, Larson Davis, and Accumetrics.

Revenue is generated through four streams: quote-based hardware sales of vibration shakers, accelerometers, signal conditioners, calibration systems, and NDT systems; a transactional rental program with published domestic and international pricelists; professional services for factory transducer recalibration and proficiency testing; and specialized industrial hygiene rentals of noise dosimeters, sound level meters, and human vibration meters. Go-to-market combines direct sales with application experts reachable by phone, email, and online quote request, an inside-sales motion via product-category contact forms, and event-driven demand generation through trade shows (IMAC, NCSLI), training seminars, and webinars. With 101–250 employees and operations across nine countries, the company serves both enterprise and mid-market customers across horizontal test, measurement, and compliance use cases.
