  • Triaxial Linear Accelerometers

    SA-307LN - Columbia Research Laboratories


  • ULF / VLF Research Receiver

    Type RAS-1 - National RF, Inc

    Called the RAS-1, the receiver is designed for ultra low and very low frequency scientific research work, including the exploration of low frequency emissions due to seismic and earth-quake activity, study of atmospheric phenomenon such as "whistlers", and low frequency Sudden Ionospheric Disturbance (SID) and electromagnetics phenomenon.

  • Borehole 3D Geophones

    GFA 50/100 - PASI srl

    GFA down-hole 3D geophone has three 10Hz geophones - oriented according to the x-y-z axis -housed inside a cylindrical probe for the determination of the time of arrival of the type ''''s'''' and type ''''p'''' seismic waves. The piston wall-clamping device can fit drilling well of a diameter between 50mm and 110mm (larger diameter on request). The mechanic clamping system with pneumatic piston can couple rigidly with the well casing, so to reflect seismic real signals at the best, avoiding the trouble of lacerating gasbags typical of most low-cost systems. The probe has a robust cylindrical metal case that can assure a long use in field conditions; the special signal cable (graduation 1m) and the air tube are delivered on a special reel, for a total weight of less then 15 kg (GFA-60).


    SensoBrick® - AMS Technologies AG

    The process of implementing a damage detection and characterization strategy for engineering structures is referred to as Structural Health Monitoring (SHM).SensoBrick is the complete and self-sufficient solution in-a-box. Its embedded sensors get you in control of thermal-, seismic-, vibration- and settling-induced actions and, thanks to the high power battery-pack, for many years.

  • Force Balanced Accelerometer

    PA-23, PA-23BH, S-230 - Geotech Instruments, llc

    The Geotech Model S-230 is a high resolution, 1-component, force balanced accelerometer capable of meeting the noise and stability requirements of the most demanding seismic studies. It features a very wide frequency response (DC to 90 Hz) and an internal calibration coil.

  • Vibration and Position Monitors

    Riverhawk Company

    Our Vibration Monitors measure vibration double amplitude (displacement) or vibration severity (velocity). There are two ways to sense vibration: Relative to the frame or bearing cap using proximity probes or Absolute which is relative to a point in space (i.e. seismic displacement pickups, velocity transducers or accelerometers).

  • Broadband Seismometers

    Güralp 3 series - Güralp Systems Ltd

    The Güralp 3 range of compact three-component broadband seismometers are suitable for surface vault, subsurface vault, posthole and borehole installations. The instruments are thoroughly proven and have been in continuous production since 1987. The Güralp 3T is widely used on many National Seismic Networks, with over 3000 triaxial instruments deployed worldwide. The instruments can be supplied with built in digitisers, acquisition modules and a range of storage and communications options.

  • Electrodynamic Velocity Pickup

    IMV Corporation

    The principle of Reciprocal Pendulum type Pickup is to induce voltage by reciprocal motion of the seismic mass with a coil in the magnetic field being suspended by a diaphragm or coil spring.. Because of its High Sensitivity and Advanced Linearity, it is suitable for detection of malfunction or deterioration of rotational machineries. Due to its structure, mounting should be done carefully for its direction or angle.

  • Single Channel Vibration Monitor

    SCM1100 - Riverhawk Company

    The SCM1100 is a Single Channel Monitor for vibration monitoring utilizing the Riverhawk A1 seismic sensor. It is a direct replacement for the older V/P-T3, VT-11A, and Series 2000 TriLight products. Through the interconnecting cable, the A1 sensor receives an excitation signal from the monitor and in turn provides an output back to the monitor. The monitor processes, filters, conditions, measures and displays the signal.

  • Slip Table Assembly

    CSTA Series - Unholtz-Dickie Corporation

    Unholtz-Dickie introduced the Combined Slip Table Assembly (CSTA) in the late 1960''s to meet the demand for positive mechanical alignment between the shaker and its companion horizontal slip table. The challenge was to achieve this positive, permanent alignment feature without requiring an expensive seismic mass in the vibration lab floor. The original CSTA design has been continuously improved over the years and has now become the industry standard for permanently aligned, integral reaction mass slip tables.


    Bloomy Controls, Inc.

    A centrifuge model at a scale of 1/N can be subjected to a steady acceleration field equivalent to N times earth's gravity, and simulate severe stress conditions of a hazard on the model. By applying appropriate data acquisition techniques, the stresses and response of a geotechnical system can be verified throughout the model. This includes measurements in the ground at different locations, the movement of a structure, and video imagery of a sequence of events leading to a seismic event.

  • Environmental Monitoring Software

    Antelope - Kinemetrics, Inc.

    Antelope Environment Monitoring Software is a distributed open-architecture UNIX-based acquisition, analysis and management software system. It is designed to provide a comprehensive set of environmental monitoring data and processed information in real-time. Finely engineered as an all-in-one system, Antelope integrates state-of-the-art technology and scientific advances, making it ideal for monitoring seismic events from local/regional, national and global networks and arrays.

  • Transmitters

    XT Series - Riverhawk Company

    The XT-101 Vibration Transmitter converts the vibration signal as sensed by a proximity probe or seismic senor to a DC voltage which proportionally controls a 4-20 mA current loop for a specified vibration range such as 0-5 mils peak-to-peak, 0-125 microns peak-to-peak. Please take note that the loop current solely powers the transmitter. The XT-101 Model is most commonly used.

  • Sub-Bottom Profiling Systems

    HMS-622 - Falmouth Scientific, Inc.

    The HMS-622 CHIRPceiverTM and its associated transducers and arrays can fill a wide range of sub-bottom survey needs. It is available in dual and single frequency configurations, and supports three frequency bands: standard LF (1KHz-10KHz), as well as optional ULF (200Hz-2KHz) and HF (8KHz-23KHz). A direct A/D input is available for the FSI Bubble GunTM or other seismic systems, and it has an industry-standard Ethernet interface for data and control signals
