A1220 ANKER Low-frequency flaw detector

Ultrasonic flaw detector А1220 ANKER is designed for ultrasonic inspection of anchor bolts from 20 to 40 mm in diameter of understructure of steel supports of the overhead control system. The instrument can be as well used to evaluate the condition of anchor bolts of understructure of the metal floodlight towers.

Ultrasonic flaw detector А1220 ANKER  is designed for ultrasonic inspection of anchor bolts from 20 to 40 mm in diameter of understructure of steel supports of the overhead control system. The instrument can be as well used to evaluate the condition of anchor bolts of understructure of the metal floodlight towers.

Application

  • The flaw detector can inspect the anchor bolts of understructures without excavation when access is granted to the upper end surface of the bolts with overall length up to 3000 mm.
  • When dealing with the stack anchor bolts the instrument can inspect the upper section of the anchor bolt up to its welding point with the reinforcement bar.
  • Besides the anchor bolts the instrument can inspect the extended objects (pipes, rods, reinforcement bars, sheets, etc.) by wave guide technique. Inspection is carried out on the end surface of the object.

Description

Low frequency flaw detector А1220 ANKER works in the echo method mode at which the A-Scan of the signal is represented in real time. Condition of the anchor bolts is evaluated by presence, level and location of the amplitude of the ultrasonic signal on the sweep (X scale) reflected from the counter surface of the bolt and registered at its longitudinal scanning.
The flaw detector is represented as an electronic unit of a small form-factor equipped with a large high-contrast TFT display and a keyboard. Measurement results are presented on the display as A-Scans of the signal.

The S0205 0.025A0R20Х20CL low-frequency normal single-element ultrasonic transducer of longitudinal waves can be connected to the electronic unit by means of the LEMO-LEMO single cable. Principal operating frequency of this transducer is 25 kHz. The transducer has a large bandwidth (no less than 100%) and a liquid acoustic contact.

Distinguishing features of the S0205 0.025A0R20Х20CL transducer is low level of its own reverberation acoustic noise, short transmitted acoustic pulse (1.5 – 2 of impulse period) and high level of energy efficiency.
Despite multifunctionality the instrument is easily operated due to its intuitive interface and icons menu providing quick access to main settings and functions of the instrument.
Ergonomic design of the flaw detector and its light weight (as little as 800 grams), as well as capability of fastening the electronic unit in the specialized pad, provide convenient operation of this instrument in hard-to-reach areas and allow its working at height.
All inspection results are recorded into the instrument’s memory and can be transferred via the USB-port to the external PC for further processing, registration and archivation.
