The Metromatics Series MM131A, MM132A, MM232A and MM146A are High Sensitivity Accelerometers. Do you need a sensor that offers ultra-sensitive detection of low vibrations in critical applications? Such as bridge structural testing, vibration monitoring, earthquake monitoring, and geological structure research. Then, look no further than our range of High Sensitivity Accelerometers.
Unmatched Sensitivity and Versatility
Powered by cutting-edge technology, these accelerometers boast an unparalleled sensitivity range of 1.0 to 10.0 V/g (+/- 10%) and 1,000 to 10,000 pC/g (in our 232A Series), making them perfect for capturing even the faintest vibrations. Paired with a measuring range of +/- 5.0 to +/- 0.05 and a frequency range from 0.1 to 2,000 Hz, you can trust these devices to give you the precise and reliable data you need, when you need it.
Built for Extreme Conditions
Engineered to withstand the harshest environments, most of our accelerometers operate effectively within a temperature range of -40 to +121 degrees Celsius. Crafted from stainless steel and featuring a ceramic/shear sensing element, these robust units are sealed by welding or epoxy glue in some of the 146A Series, guaranteeing longevity and durability.
Compact, Heavy-Duty Design
Weighing in at just 280 grams, these accelerometers offer a powerful performance in a compact form factor. Whether you’re in the lab or out in the field, their lightweight and durable build ensures easy installation and low maintenance. Please note that a couple of the 146A Series models weight peaks at 1500 grams.
Isolation That Stands Out
Choose the MM131A Series for case isolation greater than 10^9 or the MM132A and MM232A Series for ground isolation greater than 10^9. Whatever your specific isolation needs, we have a solution that’s right for you.
Additional Features:
Easy Installation: The straightforward design allows for quick setup, so you can start gathering data immediately.
Warranty and Support: With a one-year warranty our technical customer service team is ready to assist you with any questions or issues.
