Product Features

  • 16-bit internal digital error correction
  • 316L SS flush-diaphragm sensor
  • Small, rugged package withstands harsh environments
  • Being calibrated and serialized, insures performance and NIST traceability
  • Unique cable seal system ensures water-tight integrity

Overview

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.

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!
