Caldera: A better short-period solution
The Caldera is our answer to seismologists who want a simple, robust short-period seismometer. The Caldera was designed to be electrically similar to Nanometrics Trillium Compact in that the pinout matches and the output voltage is +/ 10 Volts differential. Caldera is ready to connect to a Taurus or Centaur.
As a stripped down version of the Sixaola, the Caldera maintains the following advantages over the much acclaimed Lennartz 3D:
- We have extended the flat portion of the geophone’s response curve even lower to 0.5 Hz and added an additional pole at 6 seconds to provide for a steeper noise reduction before the 5-7 second microseism noise peak.
- The signal is converted to velocity even earlier on in the circuit. This is unique to OSOP’s design (Thank’s Dave!). The advantage is that acceleration is not seen in any stage, thus reducing the possibility of clipping from high frequency noise.
Also available: an equivalent 3-component accelerometer.
