  • High Sensitivity Accelerometers

    Metra Mess- und Frequenztechnik in Radebeul e.K.

    The piezoelectric accelerometers on this page are intended for the measurement of lowest vibrations. Typical fields of application include the monitoring of buildings, dams, bridges, oil platforms and pipelines. These sensors are often called seismic accelerometers because they are used to monitor construction activity, volcanoes and earthquakes. Their high sensitivity is achieved -unlike other high sensitivity accelerometers- by the sensing element itself and not by internal amplification. From this results highest resolution and lowest noise.

  • 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.

  • Force Balance

    Columbia Research Laboratories

    The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.

  • Loop-Powered Transmitters and Drivers

    4-20mA - Riverhawk Company

    Loop-Powered Transmitters convert the output from proximity probes, seismic sensors, into a 4-20mA DC current, which is proportional to the input being measured. The transmitter converts the displacement or vibration signal to DC voltage and/or current for a DCS or PLC system. They control a 4-20mA current loop for a specified vibration range (ex. 0-5 mils peak-to-peak). The transmitters have a two-wire hook-up, powered solely by the loop current and have a power supply range of 15 to 36 volts.
