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 4.5Hz geophone can be supplied for vertical and horizontal orientation, which is an ideal choice for the shear-wave horizontal elements, partnering the 4.5Hz vertical geophone in a 3-component package.
We supply 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.
