PCB Piezotronics, Inc. Key Developments

PCB Piezotronics, Inc. Introduces ±5.0 Volt Series of In-Line ICP Charge Converter

PCB Piezotronics, Inc. announced the availability of a new series of ±5.0 Volt output in-line ICP® charge converters. These units are well suited for use with high temperature piezoelectric sensors operating in environments up to 500°F (260°C). The 422E5x series features five gain options allowing greater compatibility with a wide range of sensors, and comes in a small, rugged package. These charge converters also offer a less expensive alternative when compared to laboratory charge amplifiers, which makes them attractive for multi-channel applications. These units offer a simple way to convert high impedance charge output sensor signals to low impedance voltage signals. The 422E5x converters are placed between the sensor and any ICP® powered signal conditioner. They can also connect directly to a DAQ system or readout device if the system incorporates ICP® power. In both cases cost is minimized because the length of low noise cable is reduced and replaced by standard coaxial cable. The new 422E5x series also replaces the PCB legacy 422E0x and 422E1x series of in-line charge converters that have a smaller ±2.5 Volt output.

PCB Piezotronics Introduces Surface Microphone for Aerospace Testing

PCB Piezotronics announced the launch of its new surface microphone developed for test engineers taking measurements in spaces where traditional microphones won't fit or outdoor environments and wind tunnels, where the effects of wind noise on measurements are a concern. Designed using computational fluid dynamics modeling, the new model is a low profile microphone and surface mount pad that greatly reduces the impact of undesired air pressure on the microphone during the measurement process. Model 130B40 is an all-in-one, prepolarized microphone and preamplifier combination with a water and dust resistant cover. Key features are its maximum dynamic range allowing measurements up to 142 dB and a 32 dBA low noise floor. Standard on this unit is TEDS v1.0. Typical applications include: wind tunnel testing, airplane panel testing, acoustic fatigue analysis, and window surface testing. The surface microphone can be used in any flush mount application and can be embedded into a wall or mounted with adhesive on flat or curved surfaces. The height is 1/8" (3mm), making it an excellent choice for applications that require the microphone to have a low profile. Model 130B40 is a quality acoustic measurement sensor with a small footprint and a very competitive price. The new surface microphone is in stock and available for immediate shipment.

PCB Piezotronics Introduces New Probe Microphone for Measurements

PCB Piezotronics, Inc. announced 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) is comprised of four components: microphone, preamplifier, housing, and several probe tips of different lengths. The components work together to provide a maximum operating temperature of 800C, 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. Total system cost is reduced with the prepolarized design, which is powered by ICP or any 2-20 mA 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 polarized microphones.
