PCB Piezotronics Microphones now available with Fast Delivery
and Exceptional Prices
PCB Piezotronics, a world leader in vibration, acoustic, pressure,
force and torque sensors has announced the availability of many
of its most popular microphones on less than five days delivery
with pricing that gives exceptional value compared with competitive
products. In addition to the fast delivery and low pricing, the
majority of models are offered complete with five year warranty.
The most popular model in PCB Piezotronics' range is the model
378B02 ½-inch (12.7mm) prepolarised microphone that is
ideal for high accuracy applications where high sensitivity is
required for free-field response type measurements. Applications
include precision sound level measurements, R&D, hearing
preservation and safety, vehicle pass-by noise, machinery preventative
maintenance, environmental noise monitoring, anechoic chamber
and loudspeaker measurements. At £610, the model 378B02
offers exceptional value with TEDS (Transducer Electronic Data
Sheets) built in, 50mV/Pa sensitivity, frequency range from 3Hz
to 20kHz, dynamic range to >135dB and operating temperature
range from -40 to +120°C (HT version).
A range of prepolarised ICP® array microphones is available
for use in consumer goods and R&D laboratory testing. These
offer a cost-effective alternative for multi-channel testing
applications with a low per-channel cost. Suitable for measuring
sound within the normal range of human hearing capability, series
130 array microphones are single piece units that include a built-in
preamplifier.
Offering excellent phase specifications, multiple series 130
microphones can be mounted and spaced in a predetermined pattern
coordinated with software to transform a complex sound field
and project an effective map of the acoustic energy flow enabling
end users to pinpoint the noise source and determine the speed
and direction of sound. With the 130E20 at just £189 per
unit, the series 130 array microphones are an excellent choice
in a wide range of applications such as noise identification,
near-field acoustic holography, sound pressure mapping, beamforming
and other large channel count applications. TEDS simplifies the
identification of each array microphone.
A new addition to PCB Piezotronics' microphone range is the model
377B26, a high temperature probe microphone and preamplifier
that is capable of measuring sound in environments up to 800°C.
Comprising a ¼-inch (6.35mm) prepolarised microphone and
preamplifier within a protective housing incorporating an impedance
tube to minimise reflections and ensure accuracy, the 377B26
probe comes with 20, 40, 60, 80 and 160mm stainless steel tips,
each acting as a low pass filter. The shorter tips offer the
highest frequency capability while the longer tips enable measurements
in the highest temperature environments. Also included are a
heat sink and flexible probe tip.
The 377B26 probe microphone with sensitivity of 2.15mV/Pa, high
dynamic range (164dB) combined with its high temperature capability
make it an excellent choice for exhaust noise testing in automotive
and aerospace engines. Additional applications include testing
in confined areas, speaker diaphragm testing, acoustic impedance
measurements, telephone analysis, musical instrument analysis
and leak detection in industrial environments.
PCB Piezotronics' microphone range also includes surface models
and side vented types and the company will also be introducing
several new models in the near future.
Supporting its microphone range, PCB Piezotronics offers a free
microphone handbook that can be downloaded from the company's
website. There is also an independent competitive comparison
and a brochure available alongside a range of informative videos.
