Introduction

The HYT500B is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port.

The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.

The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

Features of the Instrument

The instrument extends the performance and range of applications that are capable of being satisfied by a portable instrument. The quality, portability, durability, and dependability that you have come to expect from the popular Huayin HY Series of instruments remain.

Display

Hi-resolution (320×240 pixels) multi-color TFT LCD with 4 user-selectable brightness control provides high contrast viewing of the waveform from bright, direct sunlight to complete darkness.

The hi-resolution multi-color TFT LCD display with fast 60 Hz update gives an “analog look” to the waveform providing detailed information that is critical in many applications including nuclear power plant inspections.

Range

Up to 9999 mm in steel. suitable for use on large work pieces and in high-resolution measurements.

Pulser

Pulse Energy selectable among Low, Medium and High.

Pulse Width tunable from 0.1µs to 0.5 µs to match the probes with different frequency.

Pulse Repetition Frequency adjustable from 10 Hz to 1 KHz in 1 Hz increments.

Damping selectable among 100Ω,200Ωand 400Ωfor optimum probe performance

Test Modes include Pulse echo, dual and thru-transmission

Receiver

lCrack Height Measure function

lWeld figure feature

lMagnify gate: spreading of the gate range over the entire screen width

lVideo Recording and play

lAuto-gain function

lEnvelope: Simultaneous display of live A-scan at 60 Hz update rate and envelope of A-scan display

lPeak Hold: Compare frozen peak waveforms to live A-Scans to easily interpret test results.

lA Scan Freeze: Display freeze holds waveform and sound path data

lB Scan display feature

Real Time Clock

The instrument clock keeps running tracking the time.

Communication

High speed USB2.0 port.

The optional DataPro software helps manage and format stored inspection data for high-speed transfer to the PC. Data can be printed or easily copied and pasted into word processing files and spreadsheets for further reporting needs. New features include live screen capture mode and database tracking.
