Strain Gauge Piezometer Instruction Manual
The Strain Gauge Piezometer is specifically designed to meet the rigorous environments encountered in level measurement applications and to provide repeatable, precision depth measurements.
The Strain Gauge Piezometer is specifically designed to meet the rigorous environments encountered in level measurement applications and to provide repeatable, precision depth measurements. It is available with either a ported nose cap or a piezometer nose incorporating a sintered stainless steel porous filter.
Ideal for small bore applications, and the ability to withstand rigorous environments encountered in ground and sea water depth measurements, the Strain Gauge Piezometer can also be used for dynamic pore pressure measurement applications. Highly reliable multi-stage transient* protection is standard. Each unit is shipped with a calibration card that specifies I/O conditions as well as actual data reflecting the unit’s static accuracy and thermal characteristics.
|Accuracy||±0.1% FS T.E.B.*|
|Standard Pressure Ranges||0 – 1 m through 0 – 300 m|
|Compensated Temp. Range||-10°C to 80°C|
|Pressure Output||Current: 4-20 mA
|Wetted Materials||Standard 316L SS Polyamide Fluorocarbon|
|Electrical Termination||Vented Hytrel Cable or Sealed Cable|
|Level Range (user-specified)||Infinite between 0 to 3 through 0 to 900 ft. WC|

*T.E.B.: Total Error Band: Includes the combined effects of non-linearity, hysteresis and non-repeatability as well as thermal dependencies, over the compensated temperature range, expressed as a percentage of the Basic Range. All intermediate ranges are realized by deranging from standard Basic Ranges of 30, 100, 300 and 900 ft WC.
|SUPPLY||VDC||8 – 28 VDC|
|OUTPUT||2 wire analog||4 – 20 mA|

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
