WaveForm Analyzer Model WFA-1

Cat. #WFA001
Price  $1600.00

 

Advantages:

Compared with techniques currently used for determining OFF (IR drop free) potentials, the WaveForm Analyzer / Pulse Generator (WFA/PG) system offers the following advantages:

  • More accurate potential measurements
  • Consistent IR drop interpretation
  • Simple automatic operation
  • Compact and lightweight
  • Reliable under various pipeline conditions
  • Lower cost
  • Standard auto-ranging DC and AC voltmeter capability
General Information:

The WaveForm Analyzer / Pulse Generator system utilizes state of the art computer technology to provide the corrosion engineer with an economical and easy to use instrument for removing the soil IR drop from pipe-to-soil potential measurements. The WaveForm Analyzer is a microprocessor based hand-held digital voltmeter which operates in the WaveForm Analyzer mode, as well as an AC or DC voltmeter mode. When taking readings in the WaveForm Analyzer mode, a liquid crystal display shows the "ON" potential (including the IR drop), and the "OFF" (zero current) or IR drop free potential. The system works on all structures using impressed current cathodic protection systems including natural gas distribution and transmission pipelines, oil pipelines, steel-reinforced concrete structures, underground steel tanks, water piping systems, electric power generating plants and industrial facilities.


Specifications:

 

WFA Mode:

Displays the ON and OFF (soil IR drop removed) potential in. Three voltage ranges: 0-3.0 volt (1 millivolt resolution), 0-30 volt (10 millivolt resolution) and 0-300 volt ( 100 millivolt resolution).
Requires Pulse Generators installed on all rectifiers influencing readings.

DC Mode:

Functions as an auto-ranging DC voltmeter with three ranges: 0-3.0 volt (1 millivolt resolution), 0-30 volt (10 millivolt resolution) and 0-300 volt (100 millivolt resolution).

AC Mode:

Functions as an auto-ranging AC voltmeter measuring the RMS voltage on the input waveform. Three voltage ranges: 0-3.0 volt (1 millivolt resolution), 0-30 volt (10 millivolt resolution) and 0-300 volt ( 100 millivolt resolution).

Polarity:

Automatic in DC & AC mode with negative symbol displayed and positive assumed. In the WFA mode, the negative input must be connected to the structure and the positive to the reference cell.

Input Resistance:

10 Megohm input resistance, all modes.

Battery:

9 volt alkaline battery.

Size:

6-1/8" x 3-518" x 1-3/4"

Weight:

14 oz. approx.
