Ltd. designs, builds, and supplies a wide variety of vibration
These include our high fidelity long life solid
state geophones, piezo-plastic shear transducers, and several types
of moving coil transducers.
Our solid state geophones are
capable of producing
useful data from nearly DC to several kHz. Our shear wave
directly detect fluctuating shear stresses from a few Hz to over 1.2
Moving coil types include all popular geophysical elements as well as
larger low frequency and high output types.
A full range of signal conditioning
true differential preamplification, pre-whitening, various filters,
drivers, summing networks, and telemetry.
Accessories such as our mini-shaker
