Seismic Sensors & Transducers
Displacement Pickups are vibration transducers that incorporate a spring-mass system with eddy-current damping using a frictionless pivot. This pivot is a spring flexure that serves as the ‘spring’ and a moment arm attached to the pivot serves as the ‘mass’, which allows resolutions down to the micro inch range. At frequencies above 50Hz, the mass remains fixed in space and becomes an inertial reference. A transducer within the pickup senses the motion of the mounting base relative to the inertial reference and converts it into a proportional signal. Appropriate damping results in a frequency response flat down to 10 Hz. Note that the pickup senses in only one plane, which is perpendicular to the mounting base.

Servo type Accelerometer
A motion is sensed by a displacement detector, a current is fed to the coil to get back the pendulum mass to the original position. This current will be proportional to the acceleration, that is converted to an output voltage. The Servo type accelerometer is for the Earthquake Monitoring or measurements of micro tremor on the Civil Engineering Structures because of its higher sensitivity and stability or more accurate phase responses in the lower frequency range than those of other vibration transducers.

Miniature Single Axis Accelerometers
Miniature piezoelectric accelerometers are required for applications demanding high frequency range, small size, and low weight. Product testing is necessary in today’s competitive marketplace in order to optimize designs, reduce defects, and improve customer acceptance and satisfaction. Shock and vibration testing offers a structured approach for verifying survivability in environmental influences that may be encountered during service and for precipitating incipient failures so they are not encountered by the end-user. PCB® accelerometers are used extensively for monitoring an object’s response to a programmed vibration input and for controlling the vibration profiles during testing.

Digital Accelerometer
ZET 7151
The characteristics of the primary transducer are set in the device memory and measurements are performed based on those parameters. Thus, the digital sensors releases the user from setting the measuring channels and data processing. The sensors are fixed on the measurement object while the information transmission units are mounted in electric cabinets. An advantage of the ZETSENSOR units is easy installation and uninstallation as well as indication of feed and signal transmission which, in its turn, facilitates diagnostics of the system at the facility.
