Product Description 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.TypeST-5NANatural frequency ( Fn ) 5Hz ± 7.5% Open Circuit Damping 0.60 ± 7.5%Coil resistance 1850Ω ± 5% Open circuit sensitivity80.0 V/m/s ± 5%Harmonic distortion <=0.1% Typical spurious Frequency>=130HzMoving Mass22.80gMax.coil excursion p-p3mmMax.tilt angle10oElement Diameter32mmElement Height44mmElement Weight 166gOperating Temperature-40oC to + 80oC Warranty Period 2 yearsAll parameters specified herein are rated at a temperature 20oC±2oC.2-year limited warranty on basic element exclusive of high voltage, lightening and physical abuse.
