Description
SPECIFICATION
Apparatus for inspecting non-destructive testing apparatus
The invention relates to apparatus for inspecting the operation of testing installations and instruments for non-destructive testing of materials by means of ultrasonic, eddy current or stray flux methods.
The monitoring of non-destructive testing
installations or instruments usually takes place by
means of checking elements with the aid of visible
functions such as fluorescent screen signals or
discriminator output iamps. Examination of the
functions which are concealed in operation is
complex and time-consuming. It requires
expensive measuring instruments and highly
trained monitoring personnel. Periodic inspection
of a desired frequency is therefore not normally
possible.
The object of the invention is to enable
comprehensive operation inspections to be
accomplished which are easily adaptable to each
testing installation or to each testing instrument,
objectively and reproducibly, with a significant
reduction in the time spent and in the
qualifications of the personnel.
Apparatus according to the invention for
inspecting the operation of non-destructive testing
of installations and instruments uses ultrasonic,
eddy current or stray flux methods with
connections for probes or test heads. The
apparatus comprises a programmable central unit
and testing units for generating testing signals, which testing units are operable to prepare the testing installation for use and also to reproduce the signals which are carried from the probes or test heads to the testing installation, for receiving
signals from the testing installation. The testing
units are directly connected with the central unit which communicates with the units and
conversely via a BUS-system (e.g. IEEE 488). The
reaction signals, after analysis and evaluation in the central unit, are passed to a transcribing and
recording instrument.
An embodiment of the invention is now
described by way of example and with reference to the accompanying drawing which is a
schematic representation of the inspection
apparatus.
The central unit 1 contains a freely
programmable computer with program and data
memory which controls all the necessary steps for
a monitoring of the installation or instruments. In testing unit 2a all necessary digital signals are
generated, which are necessary to prepare the testing installation 4 for testing. Testing unit 3a
prepares the digital or analog reaction signals
coming from the testing installation 4. Within testing unit 3b the checking apparatus is synchronized with the testing installation or testing instrument 4.
A testing signal which is practicable for the respective testing method is produced, programcontrolled, by the central unit 1 in synchronism with the testing installation or testing instrument 4 in the unit 2b. These testing signals may be varied, for example for an ultrasonic testing installation, in amplitude, frequency, the time position in relation to the synchronic impulse, the time length and the frequency of their occurrence.
The reaction signals of the testing installation or testing instrument 4 are evaluated by the central unit 1. The operator of the checking apparatus is informed of the result on the transcribing and recording instrument 5.
Evaluation criteria are partially determined by the checking apparatus itself. For the data of the analog amplifier in an ultrasonic testing installation, for example, the frequency spectrum of an ultrasonic testing head 6 is necessary. For this, the high-frequency signal of the ultrasonic testing head 6 on the connecting terminal 7 is taken up by the checking apparatus, digitalised, and the frequency spectrum is determined. From this, as evaluation criterion, the minimum requirement for the frequency range of the analog amplifier of an ultrasonic testing installation is derived.
1. Apparatus for inspecting the operation of non-destructive testing installations and instruments using ultrasonic, eddy current or stray flux methods with connections for probes or test heads which apparatus comprises a programmable central unit and testing units for generating testing signals, which testing units are operable to prepare the testing in'stallation for use and also to reproduce the signals which are carried from the probes or test heads to the testing installation, and for receiving signals from the testing installation, for which testing units being directly connected with the central unit which communicates with the units and conversely via a BUS system and the reaction signals, after an analysis and evaluation in the central unit, are passed to a connected transcribing and recording instrument.
2. Apparatus according to Claim 1 including a transcribing and recording instrument for receiving signals from the testing installation.
3. Apparatus according to Claim 2 wherein the instrument is connected to the central unit and receives said signals only after analysis and evaluation in the central unit.
4. Apparatus for inspecting non-destructive testing installations substantially as described herein with reference to the accompanying drawing.
