Boltight® Echometer Premier

Utilize our compact and portable ultrasonic measurement tool – Echometer Premier – for swift and accurate bolt load measurements, ensuring precision and reliability in your operations.

ULTRASONIC BOLT LOAD MEASUREMENT

Echometer Premier uses ultrasonics to measure the elongation, stress and load in fasteners. Offering quick and accurate measurements with readings displayed on easy-to-read screens.

Echometer Premier works with most bolt tightening systems and is used to monitor the fastener during the tightening process to ensure accurate initial loading. The retained load in the fastener can then be monitored at any time.

TRANSDUCER DATA & SELECTION

There are several things to consider when deciding which transducer to use:

The crystal diameter should be completely in contact with the bolt end surface.
The outside diameter should be clear of any obstruction.
The frequency should be chosen to suit the bolt length.
The larger the diameter, the stronger the signal, and therefore better results are obtained by using the largest size transducer that will fit on the bolt.
Boltight recommends the 3/8” diameter, 5MHz transducer as the best general purpose covering 90% or more of typical bolting applications.

Size (diameter)	Frequency	Application
1/8” (3.1mm)	5 Mhz	General Purpose
1/8” (3.1mm)	10 Mhz	Hi-resolution/short Bolts
3/16” (4.7mm)	5Mhz	General Purpose
1/4” (6.3mm)	2.25 Mhz	Long Bolts
1/4” (6.3mm)	5 Mhz	General Purpose
1/4” (6.3mm)	10 Mhz	Hi-resolution/Short Bolts
3/8” (9.5mm)	2.25 Mhz	Long Bolts
3/8” (9.5mm)	5 Mhz	General Purpose
1/2” (12.7mm)	2.25 Mhz	Long Bolts
1/2” (12.7mm)	5 Mhz	General Purpose
3/4” (19.0mm)	2.25 Mhz	Long Bolts
3/4” (19.0mm)	5 Mhz	General Purpose
