The VS375-LT-V2 is a passive piezoelectric AE-sensor for low temperatures down to -196 °C (77 K). It has a full metal housing.
Its frequency response is characterized by a peak at around 375 kHz. Its frequency response bridges the gap between standard frequency range and high frequency range.

The typical frequency response curve shown below was measured at room temperature.
