Accommodating R&D engineers who need to measure sound pressure in confined areas, Model 377B26 comprises microphone, preamplifier, housing, and probe tips of different lengths. Max operating temperature of 800°C suits HVAC manufacturers and test engineers performing leak detection tests. With 0.050 in. dia probe tip that allows near field measurements with minimal disturbance of sound field, prepolarized design can be powered by ICP® or any 2–20 mA constant current supply.
