Accelerometers
-
An accelerometer is used in manufacturing machine maintenance to inspect equipment vibration. An accelerometer also is used in product testing to measure the vibration of various components.A triaxial accelerometer, also called a 3-axis accelerometer, provides measurements of the following parameters: vibration acceleration, vibration velocity and vibration displacement. In this way, vibration is measured and recorded with great precision.Most accelerometer products offered by PCE Instruments are portable devices. Many feature memory functionality so that readings can be stored and retrieved later for in-depth analysis. Some accelerometer models come with a manufacturer's calibration certificate. Some accelerometer models can be calibrated to ISO standards optionally for an additional fee.

Vibration Meter
-
The input signal of the Vibration meter software, which is the output signal of the accelerometer, i.e. the vibrational acceleration signal, is filtered by means of one of four possible digital band filters. Then, based on this signal, vibrational velocity and displacement signals are calculated by means of integrating filters. Thus, the software generates three signals which are transferred to the ZETLAB data server virtual channels created by the program and having the word “Acceleration”, “Speed” or “Displacement” in their names, respectively.Signals are averaged for a selected time interval (0.1 s, 1 s, or 10 s), after which the obtained values are displayed in the dialog box elements of the Vibration meter program. It is possible to display a root-mean-square (RMS), average amplitude or peak value.

Wafer Bonder
AML
-
Wafer bonding has found many applications in the field of MST, MEMS and micro engineering. These include the fabrication of pressure sensors, accelerometers, micro-pumps and other fluid handling devices. The process is also used for first-order packaging of silicon microstructures to isolate package-induced stresses. The OAI AML Wafer Bonder facilitates both the alignment and bonding to be performed in-situ, in a high vacuum chamber. For anodic bonding the wafers are loaded cold and heated in the process chamber. For high accuracy alignment the wafers are aligned and brought into contact only after the process temperature has been reached, thus avoiding differential thermal expansion effects which can compromise alignment. The AML Wafer Bonder is excellent for anodic bonding, silicon direct and thermal compression bonding applications. These features enable the bonder to be used with virtually any processing tool.

Tactical Grade Inertial Measurement Unit (IMU)
ADIS16490 iSensor
-
The ADIS16490 iSensor® device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16490 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyroscope bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements. The ADIS16490 provides a simple, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The SPI and register structure provide a simple interface for data collection and configuration control.

The characteristics of the primary transducer are set in the device memory and measurements are performed based on those parameters. Thus, the digital sensors releases the user from setting the measuring channels and data processing. The sensors are fixed on the measurement object while the information transmission units are mounted in electric cabinets. An advantage of the ZETSENSOR units is easy installation and uninstallation as well as indication of feed and signal transmission which, in its turn, facilitates diagnostics of the system at the facility.
