High sensitivity geophone 4.5Hz (P/N: ST-4.5A) is a long coil travel version geophone with high sensitivity of 100.0V/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-4.5A sensitivity geophone can be supplied for vertical and horizontal orientation, which is an ideal choice for the shear-wave horizontal elements, partnering the ST-4.5A vertical sensitivity geophone in a 3-component package.
● Long travel version of the ST-4.5A geophone.
●Special orientations upon request beyond the normal vertical and horizotnal options.
● Widely used in industrial vibration-monitoring systems.
● Rugged construction with precious-metal, rotating-coil contacts.
● High open circuit intrinsic voltage sensitivity of 100.0V/m/s.
●3-year limited warranty on basic elements exclusive of high voltage, lightning or physical abuse.
