MPI testing meters

Magnaflux MPI Monitoring Devices deliver precision measurement and quality control for magnetic particle inspection equipment. The microprocessor-controlled Magnaflux Shot Timer and Quick Break Tester offer a quantitative way to detect and track those functions for your MPI equipment. The FSM-2 Field Strength Meter ensures accurate detection of both direct magnetic fields as well as alternating magnetic fields. These NDT monitoring solutions enhance non-destructive testing reliability, meeting ASTM standards for ferrous material inspection. Magnaflux monitoring devices provide essential calibration tools for aerospace, automotive, and manufacturing industries requiring precise magnetic particle testing protocols.

Magnaflux MPI Testing Meters

Overview

Magnaflux offers a line of magnetic particle testing meters designed to check and measure the performance of magnetic benches, electromagnetic current generators, and other magnetizing equipment as part of regular system performance checks.

Product Categories

1. FSM-2 Magnetic Field Strength Meter

Primary Function

Used for tangential measuring of magnetic field strength in both DC and AC fields.

Operation

  • A tangential field probe is attached to the workpiece's surface during magnetization
  • Hall sensor measures voltage change produced by the magnetic field
  • Measures true RMS of asymmetric magnetic fields

Kit Components

  • FSM-2 meter
  • FSM-2 reference block (Part Number: 133042)

Key Features

  • Equipped with RS 232 interface
  • Background display lighting
  • Housing meets protection class IP65 when cover is closed
  • Supplied with mains adapter and tangential field probe

Note: This meter replaces the discontinued Digital Hall Effect Gaussmeter (Part Number: 622604)

2. QB2-Plus Quick Break Tester

Primary Function

Provides quantitative verification of Quick Break function and measures the duration of magnetizing shots.

Capabilities

  • Verifies correct function of AC, Half-Wave DC (HWDC), and Full-Wave DC (FWDC) equipment
  • Verifies Quick Break function on 3-phase FWDC units
  • Can be used with coils and cable wraps over 25 inches (64 cm) diameter

Display

LCD display alternately shows shot time and Quick Break voltage after each reading

Key Features

  • Simultaneous measurement of Shot Time and Quick Break
  • Quantitative results provide true verification of equipment
  • Complies with specifications: ASTM E709, ASTM E1444, ISO 9934, ASTM E3024

Note: This meter replaces the discontinued QB1 (Part Number: 625972) and QB-2 (Part Number: 622646)

3. Ammeter Shunt Kit

Primary Function

Verifies magnetizing current output of magnetic particle inspection equipment.

Current Measurement Capabilities

Up to 10,000 amps on:

  • Half-wave DC
  • 1-phase full-wave DC

Application

Used as part of regular system performance checks to ensure equipment accuracy and repeatability for consistent magnetic particle inspections.

Compatibility

Specifically designed for Magnaflux magnetizing equipment. May not provide accurate readings for non-Magnaflux equipment due to different current control techniques.

Key Features

  • Measures AC current up to 6,000 amps
  • Measures HWDC, 1-Phase FWDC and 3-Phase FWDC up to 10,000 amps
  • Includes calibrated shunt and interconnect cable
  • Portable storage case

Accuracy Specifications

Current Type Accuracy
DC ±2% or 30 A
AC ±3% or 30 A

Standards Compliance

  • ASME BPVC
  • ASTM E709
  • ASTM E1444
  • ASTM E3024
  • ISO 9934
  • NADCAP AC7114/2

Calibration

When the calibrated shunt is connected to the magnetic particle equipment output (either contact or coil), the digital ammeter provides a traceable reference standard for calibration and verification of magnetizing equipment.

Conclusion

These meters collectively provide comprehensive measurement and verification capabilities for magnetic particle inspection systems, ensuring compliance with industry standards and maintaining consistent inspection quality.
