Product Description

ST-5N geophone is a long coil travel version geophone with high sensivitivy of 86.0V/m/s. The extra coil travel offers an advantage for higher tilt requirements and where larger amplitude signals may be encountered, for example, in industrial vibration monitoring.

The ST-5N geophone can be supplied for vertial and horizonta orentation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-5N vertical geophone in a 3-component package.

- Long travel version of the ST-5N geophone.

- Special orientations upon request byond the normal verical and horizotnal options.

- Widely used in industral vibration-mnitoring systems.

- Ideal choice for shear-wave horizontal elements.

- Rugged construction with precious-metal, rotating-coil contacts.

- High open circuit intrinsic voltage sensitivity of 80.0V/m/s.

- 1-year limited warranty on baic element exclusive of high voltage, lightening or physical abuse.
