PCB Piezotronics introduces New Probe Microphone for measurements in Small, Hard-to-Reach Areas

PCB Piezotronics, Inc. announces the launch of their new probe microphone for R&D engineers who need to measure sound pressure in confined areas.

The probe tip diameter is extremely small measuring 0.050" (1.3mm) which enables white goods, telephone, headphone, loudspeaker and musical instrument manufacturers to make measurements in small, confined and difficult-to-access areas that cannot be accessed using traditional microphones, which are typically larger. The small size of the probe tip also allows near field measurements with minimal disturbance of the sound field. This enables more accurate test results.

The probe microphone (Model 377B26) comprises four components: microphone, preamplifier, housing and several probe tips of different lengths. The components work together to provide a maximum operating temperature of 800°C, much greater than traditional test & measurement microphones. The high temperature capability and small diameter make it an excellent choice for HVAC manufacturers and test engineers performing leak detection tests at elevated temperatures. "We are very excited about the new probe microphone. The combination of the elevated temperature range and small form factor of the probe tip, allows this unique microphone design to be used in a plethora of applications where traditional microphones would not be feasible" states Mark Valentino, Product Marketing manager for the acoustics division at PCB.

Total system cost is reduced with the prepolarised design, which is powered by ICP® or any 2-20mA constant current supply. This allows engineers to use existing 2-20mA low-cost power supplies and coaxial cables which are less costly than 200V power supplies required for externally polarised microphones. An additional benefit is interchangeability with existing ICP® accelerometers, load, force, torque and pressure sensor set-ups.
