Accelerometers
Accelerometers/Vibration Sensors
-
PCB Piezotronics manufactures precision accelerometers to measure vibration, shock, acceleration, and motion for monitoring, control, and testing applications. ICP®, PE, MEMS and Capacitance sensing technologies are used to fulfill a wide assortment of measurement requirements. Accelerometers are used by field test, in factory production and design as well as Research and Development organizations to acquire critical data. In addition to our precision miniature units, rugged accelerometers and vibration sensors for industrial machinery vibration monitoring are offered by our IMI Sensors division.
PCB's single axis and three axis (triaxial) accelerometer configuration parameters include sensitivity, temperature, frequency response, amplitude response, form factor and lead wire grounding. Accelerometers are critical for evaluating proper performance of equipment or structures. Such applications usually require proof of calibration of the entire measurement system from the sensor through to the final output. PCB calibrates all products traceable to NIST and includes a calibration certificate with each sensor shipped.
The most commonly used technology is ICP® accelerometers. These sensors require ICP® Power supplied. Most modern data acquisition, digital control, and portable data systems provide ICP sensor power. ICP Sensors can be referred to as Voltage Mode output sensors. Our PE sensors can be referred to as Charge Mode output sensors. Each directional axis measured requires one channel of the data system or signal conditioner.
Accelerometers can be referred to as accelerometer, accelerometers, accels or accel or the industrial community may refer to them as vib sensor or vib probe. Lifetime Warranty is standard with our Platinum Products offerings.

Voltage mode (ICP type) sensors can only operate to a limited ambient temperature. The ICP sensors internal electronics is the limiting factor at high temperatures. Many test articles, such as gas turbines, steam turbines, jet engines, high power motors, exhaust systems and under the hood testing have high temperatures exceeding this types sensors temperature rating. In order to properly function at these higher temperatures a different sensor technology is needed. PCB®’s Charge Mode Output accelerometers utilize piezo-ceramic sensing elements to directly output an electrostatic charge signal that is proportional to applied acceleration. This type sensor is termed a PE style or charge mode style. These sensor can operate at extreme high temperatures.

The force sensor serves to provide a measurement of the amplitude and frequency content of the energy stimulus that is imparted to a test object. Accelerometers are used in conjunction with the hammer to provide a measurement of the object’s structural response due to the hammer blow. A variety of tips supplied with each hammer permit the energy content of the force impulse to be tailored to suit the requirements of the item under test.
Using multi-channel data acquisition and analysis software, the test engineer is able to ascertain a variety of mechanical properties leading to an understanding of an object’s structural behavioral characteristics.

Force Sensors
-
PCB®’s quartz, piezoelectric force and strain sensors are durable measurement devices which possess exceptional characteristics for the measurement of high frequency dynamic force and strain events. Typical measurements include dynamic and quasi-static forces as encountered during actuation, compression, impact, impulse, reaction, and tension.
Since the measurement signal generated by a quartz sensor will decay over time, long-term, static force measurements are not feasible. However shorter-term, or “quasi-static”, measurements are possible within certain time limits, depending upon the sensor and signal conditioning used.
Due to this limitation, it is not practical to use quartz force sensors in weighing applications where strain gage type load cell is best suited. For dynamic force applications; however, quartz force sensors offer many advantages and several unique characteristics that make them ideal choice for many dynamic force measurement requirements.Highlights:

Highlights:- High sensitivity
- Tension/compression models

Strain Sensors
-
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 and 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.
ICP® Strain Sensors For Process Monitoring/Quality Control
The Series M240 Industrial ICP® Strain Sensors incorporate piezoelectric quartz sensing crystals that respond to a longitudinal change in distance. The resultant strain measurand is an indirect measurement of stress forces acting along the structure to which the sensor is mounted. As such, these devices can provide insight into the behavior of mechanical systems or processes that generate an associated machinery reaction.
Monitoring such measurement signals can provide the necessary indication for process interrupt and pass/fail decisions or for determining wear and degradation of equipment and tooling. The sensors are used for controlling processes in plastic injection molding, spot welding, stamping, and pressing, as well as monitoring processes and final product quality. These devices are easy to install and can be powered by any ICP® sensor signal conditioner such as our DIN rail module 410B01.
In additional to providing ICP® power, the 410B01 serves as an interface between sensor and machine control. Features such as independent peak and continuous outputs, gain, and selection of AC/DC coupling make integration straight forward. Strain Sensors
