Tellus-L 1 second is a cost-effective short band seismometer that
can be used both in active and passive seismology which offers excellent
Tellus-L is manufactured with 4.5 Hz geophones and offers electronically extended frequency response through an inverse-filter function. Low noise components and a compensation circuitry assure high dynamic range and stability.
The Tellus-L’s standard flat bandpass ranges from 1 to 100 Hz, 0.2 to 100 Hz is available on request.
The transduction factor is 120 V/m/s and the output is differential.
It’s rugged design and IP68 protection make it ideal for harsh environments and for field use, moreover a metallic spike facilitates the installation in the ground.
Tellus-L comes in vertical or tri-axial variant.
