- ctdcal.equations_sbe.sbe_altimeter(volts, coefs, decimals=1)[source]¶
SBE equation for converting altimeter voltages to meters. This conversion is valid for altimeters integrated with any Sea-Bird CTD (e.g. 9+, 19, 25). Sensor ID: 0
- Parameters
volts (array-like) – Raw voltages
coefs (dict) – Dictionary of calibration coefficients (ScaleFactor, Offset)
- Returns
bottom_distance – Distance from the altimeter to an object below it (meters)
- Return type
array-like
Notes
Equation provdided by SBE in Application Note 95, page 1.
While the SBE documentation refers to a Teledyne Benthos or Valeport altimeter, the equation works for all altimeters typically found in the wild.
