4-20mA Piezometer
The 4-20mA Piezometer is engineered to precisely measure pore water pressure in fully or partially saturated soil and rock. It is one of the more commonly deployed sensors in our piezometer range.
It utilises a diaphragm-type pressure transducer, delivering a robust 4-20mA output signal that is ideal for integration with data loggers and remote monitoring systems. It boasts an advanced and durable design, with 316-grade stainless steel and hermetic sealing protecting the technology from environmental effects. The casing itself is constructed to ensure that any stresses have no impact on readings. The 4-20mA is capable of measuring pressures from -50 kPa to 3500 kPa, accommodating a wide range of monitoring needs. Key specifications:- 100, 200, 350, 700, 2000 and 3500 kPa pressure ranges
- Constructed with 316-grade stainless steel
- Inbuilt thermistor to monitor temperature changes
- Operating temperature range of -20 to +80°C
- 19mm diameter
Our team integrates the 4-20mA Piezometer into borehole monitoring systems to gather continuous data and integrate with automated platforms. Its robust 4-20mA output allows for reliable communication with remote logging and telemetry systems, making it ideal for long-term groundwater monitoring and pore pressure assessments.
In tailings dam monitoring, we uses the sensor for accurate data from within dam walls, foundations and downstream areas. Its durability, wide pressure range, and compatibility with automated alert systems make it suitable for high-risk sites such as these Other applications for the 4-20mA include:- Slope stability assessments
- Aquifer monitoring
- Compliance support
