Accelerometers are either permanently mounted or carried from point-to-point in a route-based measurement or analysis scheme. The entire measurement system, however, can take on a variety of forms, depending on sensor type and the goal of the monitoring program. The following examples illustrate vibration measurement and monitoring systems.

High Frequency Accelerometer
For vibration monitoring, testing, and frequency analysis of high-speed rotating machinery, spindles, and gears, use a sensor with a high-frequency range to accurately capture the vibration signals within the bandwidth of interest. The miniature size is also ideal for use on small mechanisms where sensor size and weight may be important factors.
Low Frequency Accelerometers
These accelerometers combine low-frequency response with high-output sensitivity to obtain the resolution characteristics and output signal levels necessary for low-frequency measurements and analysis.
Low frequency accelerometers offer these additional advantages:• Rugged, laser-welded, stainless steel housing with the ability to endure
dirty, wet, or harsh environments• Hermetically sealed military connectors• Low noise, low impedance, voltage output signal with long-distance, signal
transmission capability

High Temperature Accelerometers
These sensors withstand elevated temperature extremes common to machinery such as some steam and gas turbines. Standard and charge-mode types of high temperature accelerometers are available.
Standard, high-temperature accelerometers operate in the same manner, with the same cabling, data collection, and signal conditioning equipment, as the general purpose accelerometers.
For extreme, high-temperature requirements, charge-mode accelerometers are recommended. Charge-mode accelerometers do not contain internal signal conditioning circuits which impose temperature limits on general purpose accelerometers. However, since there is no signal conditioning circuits within charge-mode accelerometers, alternative cabling and signal conditioning equipment is required.
