Bolt stress and load measurement enhanced

Boltight has extended its range of ultrasonic measurement devices with the introduction of Echometer+. The new device uses the latest ultrasonic measurement technology and offers even more features and performance than Boltight's original handheld Echometer. It can accurately measure load, stress and elongation on bolts up to 25.40m long.

Used for monitoring critical bolting applications, either during the installation of new plant or while carrying out routine maintenance, the Echometer+ works by measuring the time of flight of a sound wave as it travels through a bolt. When the wave hits the end of the bolt it reflects back into the transducer.

This enables a measurement to be taken. A new automatic correlation feature on the Echometer+ ensures accurate and repeatable transducer placement. The Echometer+ can be set to measure elongation, load, stress and strain.

As well as being able to measure much longer bolts (25.40m versus 2.44m), Echometer+ offers much more control in terms of how a waveform is transmitted with nine different pulse width options to select from.

This is invaluable when an operator is finding it difficult to get a reading, perhaps when there are unusual bolt materials involved.

The new device is larger in size than the original handheld Echometer in order to incorporate additional hardware, including a sunlight readable colour screen and built-in rechargeable batteries.

It features a 4GB internal SD card and a 64GB external SD card memory slot. Recorded data can be transferred to a Windows PC or Apple computer via a USB 1.1 port. Files can also be exchanged with the handheld Echometer.

Said Dave Metzger, Boltight's Business Development Manager: "The new Echometer+ is an excellent addition to our range of ultrasonic measurement devices. It complements the smaller handheld Echometer by offering more power, performance and functionality. It would be ideal for use inside a factory or laboratory environment, rather than working outdoors, where the extra features would be more beneficial than overall portability."

Echometer+ works with all bolt tightening systems and is available ex-stock for immediate delivery. It is supplied in a strong metal case with full operating instructions and a two-year warranty. Transducers and temperature sensors are interchangeable with the original Echometer. Training on how to use ultrasonic measurement competently is available on-site or at Boltight's UK training facilities.
