Models 934M8 and 934M9 high-intensity acoustic sensors measure gas-borne sound in the 2-Hz to 6-kHz frequency range.
The sensors are constructed of corrosion-resistant nickel alloy and withstand temperatures up to 700°C. Isolated case construction provides electrical isolation, which is said to help deliver accurate wideband pressure data. Each sensor incorporates a 2-in. integral hard-line extension with a standard 10-32 connector, differing only in their mounting configurations.
