Delta Sigma: Fast, Easy & Accurate
The most advance instrument available to control or verify bolt elongation and load in the field or lab.
Delta Sigma Ultrasonic Bolt Load and Elongation Measurement Instrument
The Delta Sigma pulse-echo ultrasonic time-of-flight (TOF) measurement device; measures, displays, stores and transfers bolt load and elongation data in a new, single purpose unit. The Delta Sigma uses a rugged, sealed color touch screen for all operator I/O. The screen uses proven medical touch panel hardware. The measurement system is a hybrid technique, using the best of both analogue and digital signal processing techniques for fast signal acquisition and precise single shot TOF measurement.
All data is logically presented on a 4.3” color, resistive touch screen, usable with gloves. Data and digital signal traces are stored for later display and transfer. The unit has automatic temperature compensation through an included magnetic temperature probe. The novel memory system has a secure sector for all bolt data and a “public” sector for transfer via USB to computer.
The Delta Sigma is powered by proven Li Ion batteries or through dual charger inputs: fast charge standard external 9V supply or the waterproof micro USB connector from any standard 5V USB device, battery pack or power supply.
Intuitive software developed specifically for bolting industry, the automatic echo detection algorithm has been developed with input from the most experienced users and electronic developers in the bolt tightening industry! Communicate to any PC with standard USB connection.
Acoustic Velocity
Applying a voltage to the piezoelectric element in a transducer causes the piezo material to oscillate creating a sound or shock wave that moves from the transducer, through the coupling liquid or media and into the fastener. This type of shock wave, known as longitudinal wave, travels along the length of a fastener. A material’s acoustic velocity represents the speed with which sound moves through it. All materials have a representative, or theoretical, acoustic velocity but true acoustic velocity can vary from one sample to another of the same material and even throughout the material in a particular sample. It is important to realize that the actual acoustic velocity is not truly a constant. It varies between fasteners of like material, even when the fastener’s material composition is tightly controlled and is usually a result of the residual stress in the material from the manufacturing and heat-treating processes.
Scientifically Tested
Industry Proven
The Delta Sigma Instrument has been tested and approved by several companies, associations and institutes world wide. Among others, DNV GL main laboratories is one of the most acknowledged and respected for independent and
un-biased testing.
Boltsonics
Vast experience with custom-made tools, special solutions, inspection and testing.
Being one of the main suppliers of ultrasonic boltmeters, Boltsonics also has a rental pool of Delta Sigma instruments and transducers.The instruments are available for rental with an initial training, online or on-site.
