Bolt Tight using ultrasonics sensor

BOLT TIGHT USING ULTRASONIC SENSOR

Utilizing the most recent ultrasonic innovation the Bolt

tight Echometer is a quick and precise approach to quantify jolt load and jolt lengthening.

The Bolt tight  Echometer utilizes ultrasonics to gauge the extension, stress and load in clasp. It offers speedy and exact estimations with readings showed on a simple to peruse screen. The unit works with all screw fixing frameworks and is utilized to screen the clasp amid the fixing procedure to guarantee precise beginning stacking. The held load in the latch can then be checked whenever.

Echometer limits the necessity for broad administrator preparing. With implicit information recording and announcing through a USB interface, the gadget is speedy and simple to utilize and offers a dependable answer for the most troublesome catapulting issue.

Using the latest ultrasonic technology the Bolt tight Echometer is a fast and accurate way to measure bolt load and bolt elongation.

The Bolt tight Echometer uses ultrasonics to measure the elongation, stress and load in fasteners. It offers quick and accurate measurements with readings displayed on an easy to read screen. The unit works with all 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.

Echometer minimises the requirement for extensive operator training. With built in data recording and reporting through a USB interface, the device is quick and easy to use and offers a reliable solution to the most difficult bolting problem.

How it works :

Quick, easy and highly accurate

The Echometer measures the time of flight of a sound wave as it travels through a fastener. A sound wave is created when an electrical pulse is applied to a piezoelectric element inside a transducer placed on the

end face of the bolt.

When the ultrasonic sound wave encounters an abrupt change in density, such as the end of the fastener, the wave reflects. This reflection travels back through the length of the fastener and back into the transducer. When the sound wave enters the piezoelectric

element, a small electrical signal is produced. This signal is used to stop a timing counter.

Ultrasound travels in a fastener at a constant speed (the acoustic veloicity) determined by the material type. Therefore the time divided by 2 and multiplied by the acoustic velocity of the material gives the acoustic length of the bolt

A measurement is taken before the bolt is tightened, and then after the bolt is tightened. The difference between the two readings is the bolt's elongation!

The Echometer can be calibrated to also read in units of Load, Stress and Strain.

Example:
Before:112.35 mm
After:113.45 mm
Difference 1.1 mm

... therefore the bolt has stretched 1.1 mm

Snappy, simple and exceedingly precise

The Echometer measures the season of flight of a sound wave as it goes through a clasp. A sound wave is made when an electrical heartbeat is connected to a piezoelectric component inside a transducer set on the end face of the jolt.

At the point when the ultrasonic sound wave experiences a sudden change in thickness, for example, the finish of the clasp, the wave reflects. This reflection goes back through the length of the latch and over into the transducer. At the point when the sound wave enters the piezoelectric component, a little electrical flag is delivered. This flag is utilized to stop a planning counter.

Ultrasound goes in a clasp at a consistent speed (the acoustic veloicty) controlled by the material sort. Consequently the time separated by 2 and duplicated by the acoustic speed of the material gives the acoustic length of the jolt

An estimation is taken before the jolt is fixed, and after that after the jolt is fixed. The distinction between the two readings is the jolt's prolongation!

The Echometer can be aligned to likewise read in units of Load, Stress and Strain.

Illustration:

Before:112.35 mm

After:113.45 mm

Distinction 1.1 mm

... along these lines the jolt has extended 1.1 mm
