High Temperature Charge Mode Accelerometers

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Charge mode output accelerometers from PCB® use piezo-ceramic sensing elements that output an electrostatic charge signal proportional to the applied acceleration. These sensors can operate at extremely high temperatures because they do not contain the built-in signal conditioning electronics that limit the temperature range of ICP® accelerometers. Charge mode sensors are used in the testing of gas and steam turbines, jet engines, high power motors, exhaust systems and automobile engines where temperatures can range from 500° F (260° C) to 1200° F (649° C).

Strain Sensors

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.

PCB Piezotronics, Inc.

PCB® has supplied high frequency, durable, quartz ballistics pressure sensors in both charge and ICP® voltage mode versions for over forty years. Keeping with our tradition, PCB continues to offer a complete line of sensors for conformal and case mouth ballistic measurements. All PCB sensors are provided with NIST traceable calibration. For pre-calibration stabilization purposes, all ballistic pressure sensors are hydraulically cycled at high pressures and most are test fired in the PCB ballistic firing range.

ICP® Accelerometers With Excellent Thermal Stability

-

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

The single and triaxial ICP® accelerometers are designed with a low temperature coefficient, wide operating temperature range, and good broadband measurement resolution, making them ideal for any vibration measurement requiring tight control of amplitude sensitivity over a wide thermal gradient. To alleviate the effects of high frequency overloads caused by metal-to-metal inputs, a low pass filter has been incorporated in all models, ensuring accurate data in the frequency range of interest.

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.
