GMH Engineering

What GMH Engineering does

GMH Engineering is a privately held engineering firm founded in 1988 by three Brigham Young University graduate students (J. Gordon, Chuck Monson Ph.D., and Greg Heiner) and headquartered at 336 Mountain Way Drive, Orem, Utah. The company designs, manufactures, and operates specialized data acquisition and sensor systems for high-shock, high-acceleration testing environments, alongside a portfolio of testing and engineering services. Core products include the DataBRICK3 rugged data logger (8 analog / 4 digital channels, 17 kHz sample rate, 4.2 million sample memory, 14-bit A/D, verified operation above 200 g), the Delta DRS1000 non-contact Doppler radar speed sensor (Ka Band 35.5 GHz, 0.5–300 mph range, ±0.34% error at 1 mph), and the HFW80 optical-encoder fifth wheel sensor (0–80 mph, better than 0.2 mph accuracy). These products support the firm's broader service practice in full-scale automotive crash testing, railroad Crash Energy Management (CEM) testing, amusement ride verification (ASTM F2137 SARC), and ISO 2631 / ISO 5349 vibration measurement, as well as custom product-development engagements.

Core offering

GMH Engineering designs, manufactures, and sells proprietary data acquisition and sensor products (DataBRICK3 rugged data logger, Delta DRS1000 Doppler radar speed sensor, HFW80 fifth wheel sensor) and provides specialized engineering testing services including amusement ride testing, vehicle crash testing and forensic engineering, vibration testing, and custom product development for clients in automotive, railroad, amusement ride, and equipment manufacturing industries.

Product overview

GMH Engineering offers a portfolio of specialized data acquisition and measurement products centered around three core offerings: the Delta DRS1000 Non-contact Speed Sensor (Doppler radar for speed/distance measurement), the DataBRICK3 Data Acquisition System (rugged portable data logger), and the HFW80 Fifth Wheel Sensor (mechanical speed/distance sensor). These products are designed for demanding testing environments including vehicle crash testing, amusement ride testing, whole body vibration testing, and railroad crash energy management testing. Supporting accessories include the RM100 Fixed Angle Mounting Bracket and RM200 Magnetic Pivot-Base Mount for the DRS1000 sensor. The SRO100 Programmable Digital Meter was previously offered but is now discontinued. The company also provides engineering testing services (amusement ride testing, crash testing, vibration testing, product development) that utilize these products.

• NASAnotableTechnology or IntegrationNASA used GMH Engineering's DataBRICK2 data acquisition system to measure velocity and g-forces on test articles for the International Space Station's emergency escape pod research. The DataBRICK survived being dropped from 10,000 feet altitude, struck desert ground at over 500 mph, was buried and recovered via excavation, yet retained usable data. This demonstrates the extreme durability and reliability of GMH products in demanding applications.

Broad incumbents

• National Instruments (NI): Large-scale provider of modular data acquisition systems and test platforms used across automotive, aerospace, and industrial testing. Competes broadly with GMH's DataBRICK in general-purpose test applications but lacks the ruggedness envelope for high-g crash testing.
• Applus+ IDIADA: Global automotive testing and certification provider operating large crash test facilities and homologation services. Competes with GMH in vehicle-to-vehicle and barrier crash testing, but at much greater scale and broader service portfolio.
• Brüel & Kjær (HBK): Danish-headquartered global leader in sound and vibration measurement instrumentation and testing services. Directly comparable to GMH's vibration testing work (ISO 2631, ISO 5349) and instrumentation products at enterprise scale.
• MISTRAS Group: Provider of non-destructive testing, mechanical integrity, and condition monitoring services across industrial, energy, and transportation sectors. Overlaps with GMH's vibration testing services at much larger scale and broader industrial customer base.
• Kistler Group: Swiss-headquartered manufacturer of high-precision sensors, instrumentation, and data acquisition systems with deep penetration in automotive crash testing, vehicle dynamics, and NVH measurement. Overlaps with GMH's instrumentation products and vibration testing services at significantly larger scale.

Emerging players

• Dewesoft: European manufacturer of high-speed data acquisition systems and signal conditioners with growing presence in automotive testing, NVH, and power analysis. Competes in adjacent instrumentation categories with rugged DAQ offerings that overlap with GMH's product range.
