Notes:

1. We use the “Pascal (Pa)” indication of sensitivity as per the recomendation of I.E.C. (International Electrotechnical Commission). The sensitivity of “Pa” will increase

20 dB compared to the “ubar” indication. Example: -60 dB (0 dB = 1 V/ubar) = -40 dB ( 1V/Pa)

2. All specifications measured at 5~35°C, humidity at 45~85%, under 86~106 kPa pressure, unless otherwise noted.
