New ultrasonic bolt load measuring equipment launched by Hydratight

1 November 2017

Joint integrity specialist Hydratight has introduced advanced electronic bolt load monitoring equipment for use on any critical bolted application.

The BoltScope Ultra is a handheld device that monitors and displays elongation, stress and load on fasteners. Hydratight has provided the system for use in oil and gas, nuclear, wind and power generation industries. However, it can support any application where the accuracy of bolt load requirements is highly critical.

The BoltScope Ultra is compact, lightweight, durable and easy to operate. It also has an anti-glare screen for use in bright conditions.

An electric transducer captures the acoustic velocity of fasteners before, during and after the tightening process. The monitored data is presented on a large, easy to read color display and recorded for offline reporting and storage. The BoltScope Ultra also has a built-in fastener temperature feature via an automatic temperature probe. Thus, temperatures can be more easily and efficiently monitored by the operator than ever before.

These units have a range of automatic settings to optimize signal detection, strength and stability. The data is displayed in a format for quick recognition by the operation. A simple one key press optimizes signal stability and strength, eliminating interrogation by the operator.

The product is provided with all associated accessories in a compact carrying case.

Ian Thompson, Hydratight’s Technical Authority, said: “The launch of the BoltScope Ultra represents a step-change in the technologies used for monitoring bolted joint operations. Its ease of use and adaptability across industries will increase joint integrity, leading to safety through clarity and consistency.”
