Product Description

SM-6 B coil equivalent 4.5Hz geophone(P/N: ST-4.5N)  is a long coil travel version geophone, which is equivalent to SM-6 B coil 4.5hz geophone. 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-4.5N geophone can be supplied for vertical and horizontal orientation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-4.5N vertical geophone in a 3-component package.


- Long travel version of the ST-4.5N geophone.

- Special orientations upon request beyond the normal vertical and horizontal options.

- Widely used in industrial vibration-monitoring systems.

- Ideal choice for shear-wave horizontal elements.

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

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


We supply ST-4.5N geophone coil, geophone element, single geophone, 3-component geophone, geophone array and geophone string with split spring connector, Mueller clip connector, 408 screw fit connector & push fit connector, KCK connector and KCL connector optional. Lead wires from O.D 4.6mm to O.D 7.8mm available.
