Hioki 8947 - Charge Input Module

The Hioki 8947 is equipped with circuits for two independently usable input channels. Easy to install, simply Slide the Hioki 8947 into the MEMORY HiCORDER for use.

The 8947 is equipped with an anti-aliasing filter that is indispensable when performing FFT analysis on vibration waveforms

Two-channel, Charge-output type piezoelectric acceleration pick-up sensor, Acceleration pick-up sensor with an internal preamp. The CHARGE UNIT 8947 is equipped with circuits for two independently usable input channels.

Convenient Features

• Because MEMORY HiCORDERs are equipped with a charge amplifier, the cumbersome amplifier, recorder, and wiring that were required with external charge amplifiers are no longer necessary.
• Formerly, conversion was required in order to obtain acceleration values from waveforms captured using an external charge amplifier together with a recorder. This is no longer necessary because the 8947 can read measured values directly.
• MEMORY HiCORDERs accommodate a wide range of input units. This makes it easy to see the correlation between various waveforms appearing simultaneously on a single time axis.

Connecting an Internal Preamp Type Acceleration Sensor (PREAMP and VOLTAGE modes)

Use a cable with BNC connector to connect the pickup sensor to the device in PREAMP mode. We recommend the Model 9198 CONNEC- TION CORD for the VOLTAGE mode.

1. Push the BNC plug onto the connector on the device, and turn it clockwise until it locks.
2. To remove the BNC plug, push the plug ring and turn it counterclockwise to release the lock, then pull it out.

Connecting a Charge-Output Type Acceleration Sensor (CHARGE mode)

Use a cable with a plug to mate with the miniature connector to con- nect the pickup sensor to the device in CHARGE mode ( #10-32 UNF miniature connection terminal).

1. Insert the miniature connector plug into the miniature connector on the device, and turn it clockwise until tight
2. To remove the miniature connector, turn the plug counterclockwise.
