* Overall Length can vary depending on flange type, Flange Code: 2 = CPRF, 6 = Cover 

See Flange page for more information on flanges.

** Gain and 3dB Beam width values have been calculated by computer simulation.

Above models are not supplied with calibration data.  For Calibrated model add /CAL to the Model No. above.

Ex: P/N 90-442-6 with Calibration becomes 90-442-6/CAL
