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.

Hydraulic & Pneumatic Pressure Sensors

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

One of the toughest applications for pressure sensors is measuring high pressure, repetitive pulses, such as those encountered in hydraulic applications. However, our pressure sensors are designed to continuously measure repetitive pulses during applications such as hydraulic cylinder “torture” testing or diesel fuel injection. Ordinary diaphragm-type sensors usually fatigue quickly in such applications.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

General purpose force sensors are offered in either stud or axial mounted configurations. They are internally pre-loaded and can be used for dynamic compression, tension, and impact force measurements. Tapped mount­ing holes on both ends of the radial connector style support link, platform, integrated link, and free-standing installations. The axial mounted type offers protection of the electrical connector and sensor cable from potential damage during drop testing and in free-standing installations. Supplied impact caps facilitate impact and drop force measurements.

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.

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

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.
