SBE-29 Strain-Gauge Pressure Sensor

Sea-Bird Electronics

The SBE 29 pressure sensor, used on our SBE 25 Sealogger CTD (no longer in production as of 2012), is a modular sensor consisting of a mechanical strain-gauge pressure transducer with thermistor temperature compensation. The SBE 29 measures absolute pressure in one of seven full scale pressure ranges from 20 to 7000 meters depth. The sensor elements and their interface electronics are modular and self-contained, providing easy installation, service, and calibration. The SBE 29 interface electronics provide a pressure-dependent output voltage (+5 to -5) and a temperature-compensation voltage of 0 to +5 VDC (30K ohm thermistor at 25° C).
