Cryogenic ICP® Accelerometers

-

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.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

High sensitivity ICP® pressure sensors are for low pressure measurements requiring excellent resolution and small size. They are used to measure small dynamic hydraulic and pneumatic pressures such as turbulence, noise, sound, and pulsations, especially in adverse environments. They are capable of measuring high-intensity sound pressures from 111 to 210 dB at any static pressure level from full vacuum to 1,000 psi (6,895 kPa).

Strain Sensors

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Conventional strain sensors are based on strain gage technology. In order to effectively measure the strain values in a force or load measurement application, a full, 4 element strain gage bridge circuit is utilized. The configuration is known as a Wheatstone Bridge Circuit. A Wheatstone Bridge has a very linear output in it’s midrange. That being considered +100% to -100% of range. Unfortunately, a Wheatstone Bridge becomes non-linear above the upper and lower extremes of range. Therefore, significant errors can result above the end points when attempting to take precision measurements. It is particularly important to take accurate measurements in some R&D or control applications. To avoid the mentioned error issues, PCB manufactures quartz piezoelectric strain sensors that output the same mV/microstrain sensitivity throughout the entire useful range. Thus, accuracy is improved and control requirements are enhanced that may occur at positive extremes of the measurement range. The models RHM240 and model 740B02 series sensors are the strain sensors for these applications.

General Purpose Single Axis Accelerometers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Motion of a rigid body can be characterized within six degrees of freedom. Providing mechanical excitation to simulate this motion as may be encountered in the real world can entail a variety of test machines. There are various pound/force vibration shakers for structural testing. Regardless of the apparatus, the goal is always to ensure that the product under test can adequately perform, and reliably survive, in the environment in which it will be deployed, or to which it will be exposed during transport. PCB® accelerometers provide the measurement signals needed to control the vibratory input and to analyze the product’s reaction to such testing.
