Temperature Sensors

Sea-Bird manufactures a large number of temperature sensors, for use in a wide range of applications. The temperature sensors are categorized into the following groups:

  • Temperature only — SBE 3 (3S, 3F, 3plus), 8, 35, 35RT, 38, 48, 56
  • Temperature and optional Pressure — SBE 39plus, 39plus-IM
  • Temperature and Pressure — SBE 26plus, 53
  • Temperature in a CTD — SBE 9plus, 16plus V2, 16plus-IM V2, 19plus V2, 25plus, 37 (SM, SMP, SMP-ODO, SI, SIP, SIP-IDO, IM, IMP, IMP-ODO), 41/41CP, 49, 52-MP. Glider Payload CTD
  • Temperature in a thermosalinograph — SBE 21, 45

Shown below are descriptions of Temperature only and Temperature and optional Pressure sensors. See Profiling CTDs, Moored / Time Series Instruments, and Shipboard Thermosalinographs for other instruments that include temperature sensors.

SBE 39plus - just a few of the configuration choices
Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery pack, RS-232 and USB interface. Configurations with internal or external thermistor, external connector, pressure.
SBE 39plus-IM
Moored Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery, Inductive Modem (IM) interface.
SBE 56
Low-cost, high-accuracy, battery-powered temperature and time logger, with user-programmable sampling interval.
SBE 38 Digital Oceanographic Thermometer
Standards-level performance of an expensive AC bridge and platinum thermometer at a small fraction of the cost. Real-time temperature data is transmitted in ASCII characters (°C or raw counts) via an RS-232 or optional RS-485 serial interface for display or logging by PC or data logger.
SBE 35 Deep Ocean Standards Thermometer
Laboratory standards thermometer that can be used both in fixed point cells and at depths to 6800 m. Remove temperature guard (shown in photo) for laboratory applications.
SBE 35RT Digital Reversing Thermometer
Temperature sensor for use with Sea-Bird water sampler systems, taking a measurement each time a bottle closure confirmation is received, for comparison with the water bottle data.
SBE 3plus Premium CTD Temperature Sensor
Fast-response, frequency-output, extremely low-drift temperature sensor, for use on SBE 9plus profiling CTD.
SBE 3F CTD Temperature Sensor
Fast-response, frequency-output temperature sensor, for use on SBE 25 and 25plus Sealogger profiling CTD.
SBE 3S Oceanographic Temperature Sensor
Slow-response, frequency-output temperature sensor, for high-accuracy industrial and environmental monitoring at fixed sites.
SBE 48 Hull Temperature Sensor
Temperature recorder installed with magnets just below water line on inside of ship, providing shipboard determination of sea surface temperature.
Lightweight instrument for use in marine profiling applications where its high speed and spatial resolving power offer the ability to characterize small scale ocean temperature features.
