4-20mA Titanium Piezometer
The 4-20mA Titanium Piezometer is designed for compatibility with industrial data loggers, the titanium piezometer is used to monitor water levels and pressure. Typical applications include:
- Monitoring pore-water pressures in corrosive environments such as salt water.
- Monitoring rapid changes in pore-water pressure such as those produced by earthquakes.
- Monitoring water levels in pumping tests.
This piezometer is typically suspended in a well. Signal cable from the piezometer is terminated at a readout station, where it can be connected to a data logger or readout device. Water pressure acts on diaphragm of the piezometer and semiconductor strain gauges bonded to the inside of the diaphragm sense the pressure and output a signal that is proportional to the pressure on the diaphragm. The signal is transmitted to the data logger or readout device via a 4-20mA loop circuit.
High Resistance to Corrosion: All metal parts, including the diaphragm, are made from titanium.
High Resistance to Noise: The electronics of the piezometer are highly resistant to electrical noise, such as that generated by pumps.
Compatible with Industrial Data Loggers and Readouts: The titanium piezometer incorporates a 4-20mA transmitter to provide compatibility with standard industrial data acquisition systems.
Suitable for Dynamic Monitoring: The piezometer can be read continously.
