CMG-5T

Accelerometer

Installation

Check you have all components and cables.

! CMG-5T strong motion broadband accelerometer

! Thick grey signal cable

! Sensor calibration data booklet

You will need a suitable digitizer or recording equipment

and a 12–24 V DC power supply. If you intend to bolt

the instrument to a hard surface, you will also need a

120 mm × 6 mm fixing bolt, and a fixing nut with spring

washer.

Keep the packaging, in case you need to transport the

sensor at a later date.

Prepare the installation site. Any solid surface, such as a concrete floor, is suitable to install

the instrument.

To create a suitable surface in temporary sites:

1. Dig a pit, or machine-auger a suitable hole for the sensor.

2. Prepare a quick-setting cement/sand mixture, and pour it into the hole.

3. “Puddle” the mixture by agitating, until the surface is level.

4. Leave the mixture for 2 - 12 hours depending on the cement type.

If you intend to bolt the instrument to a surface:

Scribe an accurate North/South line on the surface, and

grout in the fixing bolt around the middle of the line.

Place the sensor over the bolt, and rotate until the studs

and orientation lines on the instrument align with the

North/South line.

Fix the instrument in place.
