Low frequency geophone 5Hz is a long coil travel version geophone with high sensivitivy of 80.0V/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-5NA 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.
- 2-year limited warranty on baic element exclusive of high voltage, lightening or physical abuse.
