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.

Torque Transducers

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

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.

Endevco Cryogenic Charge Output Accelerometers

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

PCB's acquisition of Endevco's full line of testing sensors means all Endevco sensors are now backed by PCB's Total Customer Satisfaction (TCS) guarantee. Endevco® cryogenic piezoelectric accelerometers are built specifically for measuring vibration under cryogenic conditions down to -452° F (-269° C). Signal outputs of these units are very stable even at extremely low temperatures. Their rugged internal construction is designed to withstand multiple cycles of thermal shock with steep temperature gradient. The accelerometers are self-generating devices that require no external power source for operation and contain no electronics. This allows them to operate below the -320° F (-196° C) limit of ICP accelerometers, down to -452° F (-269° C).

Ground Isolated ICP® Pressure Sensors For High Frequency

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

PCB® Series 102B is a ground isolated version of the Series 113B. These sensors have all of the same features and benefits of the 113B Series, plus the added benefit of isolation, which helps prevent ground loop problems. This series can accommodate an optional ablative coating (Prefix: CA) to protect the diaphragm from thermal shock in flash-temperature applications.

High Sensitivity ICP® Accelerometers

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

High sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors. These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor. All units are hermetically sealed in a titanium or stainless steel housing. Models that include a 2-pin, military style connector provide the added benefit of being electrically case isolated for superior RF and EMI protection.
