Accelerometers
Columbia Research Laboratories
The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.

High Sensitivity Accelerometers
Metra Mess- und Frequenztechnik in Radebeul e.K.
The piezoelectric accelerometers on this page are intended for the measurement of lowest vibrations. Typical fields of application include the monitoring of buildings, dams, bridges, oil platforms and pipelines. These sensors are often called seismic accelerometers because they are used to monitor construction activity, volcanoes and earthquakes. Their high sensitivity is achieved -unlike other high sensitivity accelerometers- by the sensing element itself and not by internal amplification. From this results highest resolution and lowest noise.

Seismic Transducers Calibration System
Calibration of the seismic sensors should be conducted in the low-frequency domain, which means, that the relative method used for calibration of the vibration transducers is not applicable since it does not guarantee the required accuracy level. The problem is that the reference accelerometers have uneven AFR characteristic in the low-frequency domain. Thus, calibration of seismic transducers requires implementation of a different approach.

Accelerometers
Monitran General Purpose Analysis Sensors are ideal for use with portable and on-line vibration analysers, providing the user with a complete spectrum of vibration intensity against frequency. Changes in this spectrum allow the user to determine the health of the machinery to which the sensor is attached. Most analysers will store the spectral values and monitor changes over a period of time, allowing prediction of expected component life and enabling efficient planning of maintenance schedules.

Advanced Seismic Source
GI-SOURCE
Sercel developed the GI-SOURCE to reduce and suppress the bubble oscillation from a single impulsive source to simplify processing. The GI-SOURCE impulsive source is based on the same technology as the GI-SOURCE but is different in that it has two independent air chambers within the same casing : the Generator (generating the primary pulse and creating the main bubble) and the Injector (injecting air inside the main bubble so that it collapses quickly).

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.

Quantum Accelerometer
A quantum accelerometer uses atom interferometry to measure accelerations along a horizontal axis. Quantum accelerometers are able to achieve a combination of sensitivity and stability by exploiting quantum interference. As such, they will be critical components of a quantum inertial navigation unit, which will offer satellite-free navigation with unparalleled long-term accuracy. A phase locked SolsTiS system underpins this setup and provides the extremely low phase noise required to make high sensitivity measurements and dynamic frequency tunability to address multiple atomic transitions.
