The Pa993D SDI-12 submersible depth sensor has a built-in 16-bit microprocessor which enables it to perform complex high-level linearisation, temperature compensation plus self-calibrations via the SDI-12 communication protocol. Plus, the integrated temperature sensor also offers built-in density correction, all of which delivers optimum stability and ensures high accuracy of less than ±0.15% full scale (0.1% optional).
As the embedded microprocessor inside the depth sensor controls the SDI-12 interface, it can accept instructions from a datalogger, perform the measurements and complex calculations, then transfers the data back to the datalogger via the SDI-12 communication protocol.
