Overview

The Strain Gauge Piezometer 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.

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

* Conducted transients from indirect lightning activities.

**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.
