3-Component Quartz Force Rings

260 Series

PCB Piezotronics, Inc.

260 Series - PCB Piezotronics, Inc.

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.

Cable Test Box

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Cables are a critical part of any sensor measurement system and damaged cables cause frequent delays during test setup. PCB has developed a relatively simple device to test cables on a channel by channel basis for BNC, 10-32, and 5-44 coaxial connectors. Simply connect both ends of the cable and faults will be indicated for shield failure, conductor failure, or short circuit shield to conductor. Power is provided by a single, replaceable 9 volt battery.

3-Component Quartz Force Rings And Links

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.

High Temperature ICP® Accelerometers

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

PCB® offers specially designed and tested ICP® accelerometers for conducting vibration and shock measurements under demanding environmental conditions of up to 356 °F (180 °C). These sensors combine proven quartz and ceramic shear sensing technology with specialized, built-in microelectronic signal conditioning circuitry to achieve dependable operation in extreme temperatures and through repetitive temperature cycling. Laser-welded, hermetically sealed, lightweight titanium or stainless steel housings offer further protection from the environment. Prior to shipment, each sensor undergoes a battery of tests to ensure survivability for its intended use. Such tests include temperature soak at elevated temperatures, temperature cycling, and exposure to highly accelerated screening procedures with hydraulically actuated shakers.

Quartz ICP® Links

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Link-style sensors measure dynamic compression and tension. They are constructed using a force ring that is under compressive pre-load between threaded mounting hardware. The threaded mounting on both ends of the sensor supports integrated link-style installations. Versions offering full-scale measurements of 10 lb to 50k lb (45 N to 220k N) compression and 30k lb (130k N) tension are available.

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.
