Seismometer

Titan Strong Motion

Titan Strong Motion Accelerometer

The Titan is a force balance triaxial accelerometer providing exceptional performance over a wide frequency range from DC to 430Hz. The Titan is engineered for high precision free field strong motion and structural monitoring applications requiring exceptional dynamic range combined with ultra-low self-noise performance comparable to many broadband seismometers.

Trillium 240 Broadband

Trillium 240 Broadband Seismometer

The Trillium 240 is one of the highest performing weak motion seismometers in the world. An exceptional very broadband low noise seismometer, the Trillium 240 is ideally suited to portable and fixed network applications. Trillium 240 has a response flat to velocity from 240 seconds to 35 Hz and a self-noise below the NLNM from 100 seconds to 10 Hz.

Trillium Compact All-terrain Broadband

Trillium Compact All-terrain Broadband Seismometer

The Trillium Compact All-terrain Seismometer is an ultra-low power broadband seismometer specifically developed for deployments where long-term site stability is questionable, or where the ability to prepare a sensor footing is limited, such as volcanoes, ice fields, and glaciers. Incorporating a robust and reliable levelling gimbal that operates over a full 360° range, the Compact All-terrain will auto-level from all orientations ensuring continuous operation even in a constantly changing environment.

Trillium Borehole Broadband

Trillium Borehole Broadband Seismometer

The Trillium Borehole Seismometer is a very broadband seismometer designed for cased borehole deployments. The instrument is housed in a stainless steel enclosure incorporating a hole-lock mechanism to allow the instrument to be coupled to a deep borehole casing. Instrument recovery is aided by a fail-safe holelock release mechanism that prevents jamming to the casement during removal.

An advanced levelling system allows the unit to operate over a tilt range of +/-5 degrees. The axis stack is mechanically levelled to ensure that the vertical axis does not couple horizontal noise.

Trillium Posthole Broadband

Trillium Posthole Broadband Seismometer

The Trillium Posthole (PH) Seismometer is a very broadband seismometer designed for down-hole deployments. The instrument is housed in a stainless steel enclosure incorporating a high-pressure marine grade connector making it ideally suited to uncased, buried installations.

An advanced, internal levelling system allows the unit to operate over a tilt range of +/-5 degrees (+/-10 degrees optional). The axis stack is mechanically levelled to ensure that the vertical axis does not couple horizontal noise.
