PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Three-component dynamic force sensors are offered in both ICP® and charge output configurations for dynamic and quasi-static force measurement applications. Each utilizes an array of precision aligned, quartz sensing crystals. Measurements along the z-axis are proportional to applied compression, tension and impact forces. Measurements along the x and y axes are proportional to shear forces that are imposed upon preloaded crystals by the test fixture.

ICP® Accelerometers With Excellent Thermal Stability

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

The single and triaxial ICP® accelerometers are designed with a low temperature coefficient, wide operating temperature range, and good broadband measurement resolution, making them ideal for any vibration measurement requiring tight control of amplitude sensitivity over a wide thermal gradient. To alleviate the effects of high frequency overloads caused by metal-to-metal inputs, a low pass filter has been incorporated in all models, ensuring accurate data in the frequency range of interest.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

In-line ICP® charge converters play a vital role in converting high impedance charge mode piezoelectric sensor signals into low impedance voltage signals, facilitating input to readout, recording, and analysis instruments. Specifically engineered for compatibility with high temperature piezoelectric sensors, these units are capable of operation in environments reaching up to 500°F (260°C). The series boasts ±2.5V or ±5.0 V output, offering a range of gain options, all packaged within a compact and durable casing. As a cost-effective alternative to laboratory charge amplifiers, in-line ICP® charge converters present an appealing choice for multi-channel applications.

PCB Piezotronics, Inc.

378A04 - PCB Piezotronics, Inc.

The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Miniature piezoelectric accelerometers are required for applications demanding high frequency range, small size, and low weight. Product testing is necessary in today’s competitive marketplace in order to optimize designs, reduce defects, and improve customer acceptance and satisfaction. Shock and vibration testing offers a structured approach for verifying survivability in environmental influences that may be encountered during service and for precipitating incipient failures so they are not encountered by the end-user. PCB® accelerometers are used extensively for monitoring an object’s response to a programmed vibration input and for controlling the vibration profiles during testing.

High Temperature Charge Mode Accelerometers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Charge mode output accelerometers from PCB® use piezo-ceramic sensing elements that output an electrostatic charge signal proportional to the applied acceleration. These sensors can operate at extremely high temperatures because they do not contain the built-in signal conditioning electronics that limit the temperature range of ICP® accelerometers. Charge mode sensors are used in the testing of gas and steam turbines, jet engines, high power motors, exhaust systems and automobile engines where temperatures can range from 500° F (260° C) to 1200° F (649° C).

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Cryogenic ICP® accelerometers are specifically designed to operate at temperatures below the typical -65 ºF (-54 ºC) temperature limit of most voltage mode sensors. The use of specialized, built-in, cryogenic circuitry and quartz shear sensing technology promote survivability in demanding environments such as liquid nitrogen. Each sensor is hermetically sealed and individually tested to determine the thermal coefficient of sensitivity at -320 ºF (-196 ºC) ensuring reliable operation and accurate measurements. These sensors have been successfully used in the presence of liquid helium during structural testing of rocket boosters.
