ICP® Shock Accelerometers
Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage. The addition of internal mechanical isolation minimizes the high frequency stress that would otherwise be encountered by their ceramic sensing elements. This mechanical isolation, coupled with an internal 2-pole electrical filter, built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz. Depending on the specific model, accelerations in excess of 50 kg can be successfully measured. These modern designs, with their internal elastomeric isolation materials are verified through calibration to remain dynamically linear and are enabling piezoelectric accelerometers to operate in increasingly severe acceleration environments.

Cryogenic ICP® Accelerometers
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.

Modern Prepolarized Precision Condenser Microphones & Preamplifiers
Modern prepolarized microphones are designed with newer technology than traditional externally polarized microphones. Prepolarized microphones have many advantages over the externally polarized models. They use ICP® power circuitry invented for sensors by PCB®. By applying a polymer coating to the top of the backplate and embedding a charge on it, expensive 200V power supplies can be eliminated and 2-20 mA constant current supplies or signal conditioners can be used as the power source.

3-Component Quartz Force Rings
260 Series
Three-component quartz force ring sensors are capable of simultaneously measuring dynamic force in three orthogonal directions (X, Y, and Z). They contain three sets of quartz plates that are stacked in a preloaded arrangement. Each set responds to the vector component of an applied force acting along its sensitive axis. 3-component ring force sensors must be statically preloaded for optimum performance. Preloading provides the sensing elements with the compressive loading required to allow the proper transmission of shear forces. Versions are available with ranges up to 10k lb (45k N) in the z-axis (perpendicular to the top surface), and up to 4000 lb (18k N) in the x-and y (shear) axes. Both ICP® and charge output styles are available.

Torque Transducers
The technology behind our torque sensors are strain gages. These gages are arranged into a Wheatstone Bridge circuit, which converts the physical, mechanical force into an electrical signal that can be filtered, displayed, and recorded for further processing. This very accurate radiometric electrical signal is proportional to the applied mechanical force.

General Purpose Low Profile
Our low profile load cells feature an advanced structural design that makes them extremely durable, accurate, and resistant to large extraneous shear and moment loads. To perform in a linear and predictable manner, the outside diameter of the load cell must be bolted to a flat rigid surface. When this is unavailable, our factory installed base provides a convenient threaded attachment point for easy installation and use in both tension and compression. All low profile load cells are stocked with the mounting base installed, but we can remove the base upon request.

Special Purpose Instruments
The Mechanical Impedance Sensor simultaneously measures an applied, driving-point force and response acceleration of a test structure for determining parameters such as mechanical mobility and mechanical impedance. The unit consists of a precision, shear mode accelerometer and a quartz force sensor in a common housing. Installation is primarily facilitated at the structural excitation points, in series with a stinger and vibration shaker.
