PH Tool Phased Array Calibration Blocks No.3 - 3/4 Inch Thick

The PH Tool Phased Array Calibration Blocks No. 3 - 3/4" Thick contains all the required features of the ASME Sec V Art 4 Basic Calibration Block for non-piping applications on a longer, narrower, blocks. No. 3 blocks contain two holes at 3/32" diameter drilled through the 1.500" width, located at 1/2T and 3/4T. These blocks are designed to reduce echo interference when performing a DAC/TCG calibration. The 1/2T hole is isolated from all other reflectors, while the 1/4T hole doubles as the 3/4T with the block inverted. A 150° angle has also been machined into the block ends to diminish corner reflections. The 1/2T hole signal is thus free of other reflection sources to sound path distances over 6 inches. Dimensions for the blocks are 0.750" thick x 1.50" wide x 16.00" long. Material options include 7075-T6 Aluminum, 1018 Steel, 304 Stainless Steel, and Special Alloys.
