Ultrasonic bolt measurement just became much easier than ever before. Accurate bolt elongation and tension measurement with a high level of confidence is now possible with minimal training using the Delta Sigma.

Turning your bolt into a load cell

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 the 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 ease of use in the bolting industry, the automatic echo-detection algorithm has been developed with input from the most experienced users and electronic developers in the bolting and ultrasonic industries! Communicate to any PC with standard USB connection

Why use the Delta Sigma

Delta Sigma used to verify torqued bolt joints

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.
