The HF Series accelerometers are precision vibration sensors based on an advanced piezoelectric material integrated with signal conditioning (charge amp) and current regulation electronics. The sensor features low noise, 300 µgrms, and wide band-width, 0.3 -10,000 Hz. The sensor’s electronics are uniquely designed to be compatible with both current loop systems and voltage mode systems. Unlike the other accelerometer series, the HF Series does not have a DC response, which means the unit will not respond to gravity or other very low frequency (<0.3 Hz) signals.

The sensor is an excellent choice for vibration monitoring of all kinds: vehicle and engine testing, shock recording, predictive maintenance, industrial vibration monitoring, acoustic and high frequency measurements.

The sensor is delivered with a calibration sheet which standardizes the sensitivity to within 2%. The sensor is available in two packages, a standard nylon package, and an optional high temperature aluminum package.

The sensor can be powered by a current source using the signal wire and ground. If powered by a current source, the signal wire is used as both the excitation signal and the sensor signal. A constant current of 0.3-20 mA is provided by either a current source such as a battery box, signal conditioner, or analyzer instrument with current source I/O capability. This interface allows the sensor backward compatibility with many older systems.

As an alternative to the constant current excitation, an unregulated +5 to +30 VDC power supply can be used. The output signal span is ±1 V centered about 3 V. The 3 V signal is the zero-g voltage offset. This interface is compatible with the accessories family and eliminates cumbersome and costly interface electronics, e.g., battery powered and line powered signal conditioners.
