SM-6 B Coil Equivalent 4-5Hz Geophone Sensor (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-4-5Hz geophone can be supplied for vertical and horizontal orientation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-4-5Hz vertical geophone in a 3-component package.
We supply ST-4-5Hz geophone coil, geophone element, single land cased geophone, 3-component geophone, geophone array and multi-geophone string with split spring connector, Mueller clip connector, 408 screw fit connector & push fit connector, KCK connector or KCL connector optional. Lead wires from O.D 4.6mm to O.D 7.8mm available.
