PCB Piezotronics Releases New High Temperature Microphone and Preamplifier



Improved Operating Range Allows Testing To +120 °C

Depew, NY - PCB Piezotronics, Inc., a world leader in vibration, acoustic, pressure, force, and torque sensors, announces the release of a new high-temperature microphone and preamplifier. Model HT378B02 is designed to overcome high temperature testing challenges associated with acoustic measurements in environmental chambers or other high temperature applications.

Previously, test engineers had access to microphones with 120°C capability but were limited by the preamplifier, which houses the electronics and powers the sensor, but operates only to 70°C. PCB's breakthrough technology allows operating temperatures up to 120°C for both the microphone and preamplifier. This allows the microphone to be used to its maximum frequency specifications. Prior to this innovation engineers were forced to use costly probe microphones with limited frequency bandwidths.

The HT378B02 is an industry exclusive condenser microphone and preamplifier combination that is used by test engineers to measure sound pressure amplitude (in Pascals or Decibels) and perform frequency analysis, in order to reduce noise, identify resonance frequencies, make products more pleasing to the ear, or preserve the human hearing. Typical applications include: under-hood automotive engine testing, aerospace engine tests, pump analysis, HVAC and general purpose acoustic testing in elevated operating temperatures.

The HT378B02 is offered with PCB's "Lifetime Warranty Plus" policy. For more information contact Mark Valentino at (716) 684-0002 or via email at mvalentino@pcb.com
