|BAT Piezometer |
BAT Piezometer is an innovative and proven technology for pore pressure measurements, which has been on the market for more than twenty years. Through the years BAT has gained a lot of experience within the field of pore pressure measurements, which we share with our clients to determine the best instrumentation to meet the specific needs for their projects.
The BAT Piezometer can be used for pore pressure measurements in both the saturated and unsaturated zones of soil. Key features of the BAT Piezometer are high accuracy combined with flexibility and long-term reliability
BAT IS Sensor - both a pressure sensor and a datalogger
BAT IS Sensor is completely self-contained and features an absolute pressure sensor combined with an AD converter and an internal datalogger.
Without complicated conversion factors this Intelligent Sensor immediately displays the measured pore pressures in the chosen engineering unit. The sensor has also been equipped with a temperature gauge.
Together with a replaceable, ordinary alkaline battery the BAT IS Sensor can collect and store data in a stand-alone mode for about eight months. The IS Sensor can also be inter-connected with other sensors in a fully digital network.
IS Field Unit
The robust IS Field Unit is exceptionally convenient for handling IS Sensor data in the field. This self-contained unit is equipped with a display and keyboard.
- Real-time readings of pressure data in engineering units
- Automatic barometric com-pensation by use of an internal pressure sensor
- Enables programming of the BAT IS Sensor and also down-loading of logged data
- Allows flexible connection to PC for data processing, by using the IS Software
BAT MkIII Filter Tip & pressure measurements
The BAT IS Sensor makes a leakproof connection to the BAT MkIII Filter Tip by the injection needle. For taking a single pressure measurement the IS Sensor is lowered down the extension pipe until it connects to the BAT MkIII Filter Tip. Simply by gravity, the injection needle penetrates the flexible septum in the filter tip. The existing pore pressure is then displayed by the
IS Field Unit.
