Overview

The sensor is protected by a clear plastic guard. During deployments, always orient the sensor downwards to reduce debris collecting on the housing.

Pressure

\[P_{meas} = C_0+C_1\cdot P_{cal}+C_2\cdot {P_{cal}}^2+C_3 \cdot {P_{cal}}^3\]

where:

C0-C3 are unit-specific calibration coefficients determined in the laboratory.

Pcal is a temperature-compensated pressure measurement
