Item # item-1067, Gauge 3 Precision Pressure and Temperature Sensing

Precision and Toughness for Field Testing

The new Vaetrix® Gauge 3® Pressure indicator from Taylor Valve Technology, Inc. is the industry's first portable precision electronic pressure and temperature gauge specifically designed for superior performance under tough field service conditions. From its reliable microprocessor-based technology, to its rugged, lightweight case, the easy-to-handle Gauge 3 sets a new standard for performance Pressure accuracy of 0.05% and highly-accurate measurement of temperature conditions in the field are a plus.

Thanks to the Gauge 3's straightforward design and commonsense display, even operators with little or no field operating experience achieve remarkable results the first time out. In fact, this pressure indicator is so well designed, it actually helps build operator confidence and ensure reliable testing results by eliminating the sources of many common operator errors. As a result, even first-time users can acquire and log sophisticated readings such as static and barometric pressure data with extreme accuracy.

Powered by two standard 9 volt batteries, the Gauge 3 is designed to deliver up to 250 hours of continuous, uninterrupted service Thanks to its unique combination of low power consumption and high memory capacity in excess of 1600 data points, the Gauge 3 is ideal for long-duration testing and logging of pressure and temperature conditions in field applications.

Optional test and performance package (TAPP®) software developed exclusively for use with the Gauge 3 extends the instrument's capabilities to enable flexible, menu-driven operations including:
  • Data retrieval and storage on disk in ASCII or encrypted formats,
  • Data printouts and hardcopy plots,
  • Data viewing via advance reporting.
Field-Proven Performance Features

Designed especially to deliver superior performance under tough working conditions, the Gauge 3 combines reliable microprocessor-based technology with rugged design to bring portable, precision electronic pressure and temperature measurement performance to field testing. This means Gauge 3 operators can count on benefiting from features including:
  • Highly-accurate pressure measurement
  • Non-volatile test data memory
  • High-resolution platinum RTD sensor
  • Multi-test data storage capability
  • Standard ASCII data storage format
    (operations encrypted download}
The Gauge 3 interface provides selectable options during field operations conducted without the benefit of a computer. The operator can also custom-program data intervals from 1 second to 15 minutes, using up to 8 different time intervals and sampling rates for each test. (Operator can alter all sampling parameters at the time of testing)

Designed to perform two standard processes, the Gauge 3 gives the operator the ability to select

Gauge Mode- to provide accurate, real-time pressure/temperature readings
Log Made
- to activate the Gauge3's data-acquisition capabilities.

Innovative Hardware & Software

The state-of-the-art electronics and software inside the Gauge 3 are every bit as advanced as the lightweight and functional package they are housed within. For example, its built-in calibration and diagnostic programs make the Gauge 3 the most reliable instrument of its type in service today.

The Gauge 3's high-resolution (0.01ºF.); adjustable platinum RTD temperature probe is designed for mounting at the test site in any standard 2 to 12 inch deep thermowell.

Documentation and software updates for operation and maintenance are available 24- hours-a-day via the Internet. Internet service is also available for return for recalibration, certification and repair of the instrument to maintain NIST certification and traceability.
