Digital UT technique in a compact desktop housing

The compact digital instruments are light-weight and handy and offer up-to-date technique which leads the user safely through the application by means of a convenient menu guidance. For the various application fields of nondestructive UT testing three instrument types are available:
  • ECHOGRAPH 1091 BASIC with all necessary functions for ultrasonic testing
  • ECHOGRAPH 1091 DAC with additional features for an easy signal evaluation with DA
  • ECHOGRAPH 1091 DGS/DAC with the additional possibility of a comfortable DGS-evaluation
A subsequent upgrade to a more capable expansion level is possible at any time later.

 Proven Measurement Technique in a Desktop Housing
 
As an alternative to the compact portable instrument ECHOGRAPH 1090 the ECHOGRAPH 1091 in a desktop housing is available, providing the same digital measurement technique and fitted with a built-in mains unit. The instrument mainly aims on stationary operation, e.g. in laboratories, but is in addition capable of executing simple automated testing tasks.
If mobile operation is required as well: An easily accessible battery compartment on the rear panel may accommodate a lithium ion battery. Thus up to 13 operating hours are possible with one fully charged battery. If a longer operating time is needed the dead battery may be replaced easily by a fresh one. The charger unit is incorporated in the instrument so charging may be executed without removing the battery from the unit. Alternatively the battery may be charged via a separate charger unit outside of the instrument.
The ECHOGRAPH 1091 is fitted with a large (16.4 cm / 6.4 in. diagonal) colour display, which permits clear perceptibility of echo indications, readings and of the neatly arranged operating menu even from a greater distance. Besides the five freely-programmable function keys for the essential instrument set-up each operating parameter may be shown in plain text and clearly arranged on the screen and selected from there.
Lesser experienced operators may start an electronic wizard which facilitates the set-up of the connected probes and the instrument adjustment.
The fast digital ultrasound electronics with high sampling rate and a pulse repetition frequency of up to 1500 Hz permits access to two monitor gates for the measurement of transit time and amplitude. Two alarm LEDs on the front panel support the user with optical monitoring of excess or dropping-below of the threshold values. The large A-scan memory holds up to 224 data sets with A-scans, parameters and time.
The new ECHOGRAPH 1091 is the ideal instrument for stationary manual UT in laboratories or similar industrial fields. By means of the optionally built-in battery mobile testing is possible as well. Since by default the monitor signals are available via digital switching outputs with a selectable statistical clearing the instrument may be used for simple automatic testing tasks as well. The interface boxes IFB which are available as accessory facilitate the connection to programmable logic controllers (PLC).
