The NEXUM pulse-echo ultrasonic time-of-flight (TOF) measurement device, measures, displays, stores and transmits bolt load and strain data in a new, single-purpose unit. The Nexum uses a rugged, touch-screen display for all operator I/O. The measurement system is a hybrid technology, utilizing the best of both analog and digital signal processing techniques for fast signal acquisition and accurate single TOF measurement.
All data is logically displayed on a 4.3-inch color touch-screen display, operable with gloves. Data and digital signal traces are stored for later viewing and transfer. The instrument has automatic temperature compensation via the magnetic temperature probe. The new memory system has a protected sector for all bolt data and a “public” sector for transfer via USB to computer
The Nexum is powered by Li-Ion batteries or via adapter: fast charging from standard external 9V power supply or the waterproof micro USB connector of any standard 5V USB device, battery pack or power supply.
Intuitive software specifically developed for ease of use in the bolt industry, the automatic echo detection algorithm was developed with input from the most experienced users and electronic developers in the bolt and ultrasonic industry! Communicate with any PC with a standard USB connection
