46AE

46AE is a 1/2" Constant Current Power (CCP) free-field microphone set for measuring medium sound pressure levels at medium frequencies. It is terminated with a BNC connector and is TEDS compatible. The 46AE is a free-field microphone set and as such, optimized for all acoustic applications, where the location of the main sound source is known and the microphone can be pointed directly at it, ensuring 0° incidence. The wide frequency range makes it ideal for general acoustic diagnostics. This 46AE conforms with IEC 61094 WS2F and IEC 61672 Class 1. The 46AE is delivered with Generation II TEDS. The calibration data is programmed into the built-in TEDS according to IEEE 1451.4 using UDID I27-0-0-0U.
