PCB PIEZOTRONICS ADDS INDUSTRY EXCLUSIVE HIGH TEMPERATURE
MICROPHONE & PREAMP COMBINATION TO ACOUSTIC PRODUCTS RANGE
PCB Piezotronics, a world leader in vibration, acoustic, pressure, force and torque sensors, is the only manufacturer that offers a microphone pre-amplifier which can withstand the same temperature environment as the microphone capsule and operate at 120°C.
Housed in a ½in package with a BNC connector, the new model HT378B02 is an industry exclusive microphone and preamplifier that operates from ICP® sensor power over a wide frequency range - 5Hz to 10kHz (±1dB), 3.15Hz to 20kHz (±2dB). The preamplifier was designed with the microphone in mind and works seamlessly to ensure optimum performance. The wide temperature range from -40 to +120°C eliminates the need for high-priced probe microphones.
The integral ICP® pre-polarised microphone is more cost-effective than using older-style externally polarised products and enables customers to use existing ICP® input analysers and DAQs (data acquisition systems).
With low noise floor (cartridge thermal noise) of 17dBA and dynamic range at nominal sensitivity of 135dBA (146dBA at 3% distortion), the model HT378B02 delivers high accuracy in a broad range of high temperature applications. These include engine analysis, manifold testing, transfer path analysis, exhaust pipes, heating/ventilating & air conditioning (HVAC) and general acoustic testing in high temperature environments.
PCB Piezotronics' new HT378B02 microphone and preamplifier complements the company's wide range of acoustic measurement products that are designed for use in applications such as noise, vibration and harshness (NVH) testing, environmental noise analysis, sound power testing, transfer path analysis, sound pressure mapping and general noise reduction.
Many products are available from stock with 3-4 day delivery including the new model HT378B02, model 378B02 general purpose acoustic microphone and preamplifier, and model 130E20 ICP® microphone with integral preamplifier. PCB Piezotronics also offers condenser, traditional externally polarised, array, probe, low-profile surface and special purpose microphones alongside a wide range of accessories including preamplifiers, signal conditioners, A-weighting filters and handheld calibrators among many others.
All standard PCB sensors and products are supplied with Lifetime Warranty Plus and are also covered by the company's Guarantee of Total Customer Satisfaction.
