Instantly measure seawater temperatures while the ship is in motion
The eXpendable Bathy Thermograph is a system that performs seawater measurement by deploying a probe. It can be used to perform measurement even in poor sea conditions. It makes it easy to perform sea temperature observation even on vessels without observation equipment.
The XBT system measures water temperatures by dropping a sensor (probe) into the water.
- XBT water temperature detection is performed using a high performance disk thermistor. Changes in water temperature are measured through the changes in the thermistor’s resistance.
- The data measured by the probe is transmitted via a signal wire which is connected to the launcher by a canister. The probe drop depth is automatically calculated based on how much time has elapsed since the probe was placed into the water, using the user-selected drop method.
