Techni Measure offers a comprehensive selection of vibration and shock exciters from the well-known manufacturer SPEKTRA. SPEKTRA specialises in developing and producing a variety of vibration and shock exciters that are essential for calibration systems. These exciters play a vital role in measurement and testing systems for small objects, such as sensors and electronic components. They are also used to apply precise dynamic forces to larger mechanical structures for modal analysis.

We can offer many vibration calibration solutions from SPEKTRA and their subsidiary APS Dynamics for a wide range of amplitudes and frequencies.

APS Dynamics offer a wide range of long-stroke vibration exciters rated for low frequencies, ranging from DC….200Hz. These systems can be used for a variety of applications, including calibration of seismic/low-frequency sensors. APS Dynamics also offers ball-bearing exciters more suited for modal testing.

SPEKTRA’s SE-2X series of exciters can calibrate most accelerometers, with excitation frequencies ranging from ~3Hz….50kHz. With an optional internal reference accelerometer to provide accurate secondary calibrations

SPEKTRA offer a range of standard calibration solutions, ranging from ~3Hz….50kHz. The SE-2X series exciters contain an optional internal reference accelerometer.

With a range of pneumatic and Hopkinson bar shock calibration solutions, we can offer shock calibration systems from 20gn….200,000gn. These exciters can also be used for a wide variety of experimental testing for industries such as aerospace, R&D, etc.

SPEKTRA offer both diffuse and free-field acoustic calibration solutions, capable of calibrating both IEPE, MEMS, and 200V supply microphones. As well as software capable of applying corrections for free-field microphones. With sound pressure levels exceeding 100dB for all diffuse field calibrators across wide frequency ranges up to 20kHz, there will be an option available suitable for your calibration requirements.

SPEKTRAs DPE-01 is a versatile pressure calibrator, capable of exciting pressures up to 16kPa across a broad frequency range from DC….1.25kHz. With the ability to generate a range of pressure signals, including pre-defined signals when in combination with a vibration controller, the DPE-01 is not just a useful calibration system but can also be used in product development.

For extreme pressure levels, we can offer an adapter for the SE-201 shock calibrator, allowing for shock pressure calibrations up to 29000psi, or to 60000 psi upon request. The main benefit of this solution is it can be used for both acceleration and pressure calibrations upon request.

SPEKTRA also offer a variety of accessories to further improve your calibration capabilities, including adapters to allow for the easy attachment of any sensors, trunnion bases to excite sensors horizontally, as well as laser vibrometers for primary calibrations.

For applications where on-site calibration checks are required, SPEKTRA offers the CV-10 and CV-05. The CV-05, being a small, handheld exciter, allows for easy in-situ checks of sensor calibrations where complex calibration information is not a requirement. While the CV-10 is better suited for simplifying/ performing full calibrations on site, with optional accessories for MEMS and Proximity sensor calibrations, as well as the dedicated eCal software which allows for easy data exportation and report writing.
