Olympus Panametrics 37DL Plus Ultrasonic Thickness Gage 37 DL Gauge

Olympus Panametrics 37DL PLUS Corrosion Thickness Gage


Advanced Ultrasonic Corrosion Gage
The Panametrics-NDT™ 37DL PLUS is an advanced nondestructive ultrasonic thickness gage that combines powerful measurement features with sophisticated data acquisition and output capabilities for applications involving pipes, tanks, and other metal structures subject to internal corrosion or erosion. The 37DL PLUS includes many innovative features that simplify true metal thickness measurements even when the exposed surface is coated or painted. The patented Thru-Coat technology measures and displays the thickness of the metal part and its coating using a ‘single backwall echo’. A Oxide/ Scale option measures and displays the thickness of the steel and the oxide/scale build-up on the inside of boiler tubes to help predict tube life. Accuracy of high temperature thickness measurements can be improved by using the Temperature Compensation feature that adjusts the material velocity for changes in material temperature. A new Average/Min mode saves the average or minimum of several successive thickness measurements.

The A-scan display is bright with great contrast and visibility. Every thickness reading in a stored B-scan can be reviewed on the 37DL PLUS and in the Interface Program. The user can select to view (Min/ Max, Alarm, or A-scan flags) flags with Grid points. The file-based alphanumeric datalogger can use longer file names (32 character max) and ID numbers (20 character max). Grid files can be expanded by adding rows or columns or by changing the incrementing direction.


Transducers
The 37DL PLUS can be used with a vast selection of dual element and single element transducers. Its full line of D790 series dual element transducers feature Automatic Probe Recognition to provide maximum gage performance for each transducer. The 37DL PLUS also has the ability to use the E110-SB EMAT transducer for no-couplant steel thickness measurements through oxide-scaled surfaces. The M2017 and M2091 transducers are ideally suited for measuring internal oxide/scale build-up on boiler tubes. The 37DL PLUS is also compatible with the PanametricsNDT complete line of Microscan single element direct contact, delay line, and immersion transducers ranging in frequency from 2 to 30 MHz. As a result, the gage can be used for non-corrosion applications involving materials such as plastic, fiberglass, composites, rubber, castings, rubber and glass. Application Auto-Recall automatically recalls 16 default and 10 custom Microscan transducer setups from the gage’s memory.
