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.

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.

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.

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.
