XT & XTP Sensors

Model XT, XTP

Low-cost, semi-expendable temperature (XT) or temperature-pressure (XTP) sensors with 3-axis accelerometer and inductive telemetry.

Description

XT and XTP sensors are low-cost, high-accuracy, semi-expendable Temperature (XT) or Temperature/Pressure (XTP) sensors with a 3-axis accelerometer (tilt). On command they sample and transmit in real time via inductive telemetry (1200 baud) to an S9 Ulti-modem or Sea-Bird IMM, using the mooring wire as the transmission medium.

Key features

  • Suited to expendable profiling drifters and thermistor chain profiling
  • Burst sampling of pressure and 3-axis acceleration at up to 50 Hz
  • Initial accuracy ± 5 millidegrees
  • Battery allows sampling every 10 minutes for 1100 days when new
  • Can be positioned anywhere on the mooring wire
