1. Introduction

Designed for non-destructive thickness measurement, the portable MiniTest 7200 / 7400 FH measuring systems are suit able for in the field or laborator y use. Working on the mag neto-static principle, the gauges enable quick and easy measurem ent on non-ferromagnetic m at er ials. The measuring system consists of a handy sensor, which is connected via a cable to the base and display unit for visualization and processing of readings. For measur ement , specially treated targ et balls made of a ferromag netic material are used as a r eference. For measurement , a target ball is placed on the material to be measured so that the material thickness between target ball and sensor will be measured. The measuring system comes with sensor stand ( available as an option) to add additional comfort of handling during measurement. For documentation a portable data printer is available. The measuring system may also be connected to a PC for data communication. For taking reading s, the sensor is placed on the surf ace of the m easuring object, the target ball is placed on the opposite side of sample. The sensor is placed on the opposite side of sample. Equipped with a strong perm anent magnet, the sensor at tracts the target ball and holds it exactly over its sensor tip. W hen moving the sensor, the tar get follows accordingly. The presence of the target ball will change the magnetic field near the sensor tip. The magnetic field changes according to the distance between target ball and sensor tip. T he change of mag netic f ield increases with the distance between target ball and sensor t ip getting smaller and can be taken as a reference for the material thickness of the sample to be measured. The sensor incorporates a Hall element to capture the change of magnetic field and to translate it into thickness.

For measuring hollow parts, a target ball is placed into the interior of sample and the sensor is placed on the opposite side in order to attract the t arget ball exactly over the sensor tip. For taking readings, the sensor is moved over the surface of sample. For measuring sheets, the sensor is placed on the surface of sheet and t he target ball is placed near the sensor on the opposite side of sheet. The target ball will automatically center on the correct measuring position and the measuring processes can be started.

For measuring large-sized parts, the sensor can be guided manually over the sample to be measured. For measuring small part s, it is recommended to use the sensor stand supplied with the sensor. Suitable for use in industrial production areas, the measuring systems MiniTest 7200 / 7400 FH measure hollow parts, containers and sheet material of all kinds such as bottles, cans, inject ions moldings, car bodies, glass, SMC components etc made of non-magnetic (non-f er r it e) m at erials.

3.2 Sensors FH 4 and FH 10

3.2.1 General Remarks

In this new SIDSP (Sensor integrated digital signal processing) procedure, all necessary measuring signals are created and complet ely processed in the sensor itself. Only the completely processed digital readings are transferred to the base unit for display, statistical evaluation and data storage. Unlike the comm only used analog procedures, the new SIDSP procedure excludes any error influences on the measuring data during transfer over the probe cable. The result is a measuring accuracy and constancy of readings that has been unmatched so far. T he complete sensor technique is integrated into a robust stainless-steel housing.

3.2.2 Sensor Models

Two sensor models are available:

FH 4 sensor to cover the 0 …4 mm range

FH 10 sensor to cover the 0…10 mm range.

Both sensors feature a wear-resistant sensor tip most suitable also for hard materials such as glass, for instance.

3.2.3 Sensor Stand

Both sensor types come with a spring-loaded V-grooved sensor stand. The use of the sensor stand ensures increased reproducibility of readings by adding stability of t he sensor dur ing measurement so that even small parts can be measured without problems.

5. Measure Mode

5.1 Important Notes on Thickness Measurement

Make sure that the operator has been properly instructed regarding the use of thickness gauges and has basic knowledge of the specific req uir ements for measurement of the application. The operator should have basic knowledge of the following:

• Selection of a measuring device suitable for his application

• Fundamentals on the magneto-static m easur ing principle

• Influences on the magnetic f ields t hr ough the surrounding field

• Influence of the surf ace pr oper t ies of the material to be tested (roug hness, build-up on the

surface)

• Statistical evaluation of measuring series

• Gravity influencing the reference ball

5.1.1 Limitations to magneto-stati c t hi ckness measurement

The information obtained f rom thickness measurements according to the magneto-static principle only refer to those parts of the test object that have been covered by the magnetic sensor . For t hat reason, be careful to draw conclusion on other parts of the measuring object that have not been covered by the sensor during measurement. In g eneral, such conclusions are only admissible if comprehensive experience and approved methods of statistical data acquisit ion ar e available.

5.2 Batch Configuration / Necessary Settings

Before taking reading s, it is necessary to make a few settings in the Configuration menu. The Configuration always refers to a cer t ain m easuring series (Batch).

5.2.1 Batch

You can continue to take readings in the active batch

You can create a new batch (only with MiniTest 7400 FH model)

You can choose an exiting batch from the database (please r efer to section 7.2).

According to sensor type and the shape of measuring object, a

automatically quit tar menu level.

5.2.3 Data Logging Mode

In the data logg ing mode you can specif y how you wish readings to be stored in memory. Several modes are available:

manually or via footswitch (Current reading, MIN, MAX)

Automatic (Auto)

Note: For logging data into memory please always proceed as follows: Put the sensor into the correct measuring position, press ESC. Then readings can be taken.

5.3 Preparing Measurement

Before measurement, the probe must be adapted to the ambient temperature. In case of high variations in temperature, the targ et ball must be lifted f rom the probe tip at regular intervals (e.g. every other minute). This is to compensate f or f r equency drif t due to variations in temperature. It is recommended to switch on the gauge for warming up around 2 to 3 minutes in order to ensure maximum measuring accuracy.

5.3.1 Calibration

According to your setting of task , you may use different calibration methods. Measuring accuracy depends on the selected calibration method. Please refer to section 6 for more details on this issue. There are three calibration methods available:

Factory

Zero only

Multi-point calibration (Zero + 1 to 4 Point(s)

5.3.2 Measurement without Sensor Stand

For measuring large-sized parts, t he sensor can be guided manually over the measuring sample. For measuring thick samples (6 m m and thicker) make sure to k eep the sensor in vertical position to the sample. When holding the sensor in horizontal position, due to the influence of gravity on the steel ball, the readings will be higher than the actual t hickness.

5.3.3 Using the Sensor Stand

For measuring small part s, bottles or other cylindrical bodies the sensor stand (supplied with the sensor) and a footswitch (available as an option) should be used.

Put the sensor into the stand and secure with the red sensor stand retaining ring.

5.4 Take Readings

5.4.1 Measurement without Sensor Stand

For measurements on large-sized sheeting m aterial or large hollow parts, place the sensor onto the surface of the object to be measured. Place an appropriate targ et ball on the opposite side of object near the sensor. The t arget ball will be attr acted by the strong permanent mag net of sensor and be positioned centrally just opposite of the sensor t ip. Keep the sensor in right-angle posit ion to the object to be measur ed and scan continuously over the surface. For storing readings, please refer to section 5.5.1.

5.4.2 Using the sensor stand

If you are using the sensor stand, position the sample on the sensor tip and keep it in r ight-angle position to the sensor. Place the appropriate tar get ball on the opposite side of obj ect. Make sure to keep the right -angle position while moving the object continuously over the sensor. For stor ing readings, please refer to section 5. 5.1. When measuring small hollow parts such as bottles e.g., put the target ball inside the object and place the object onto the v-grooved device of sensor stand. Turn the object unt il the target ball is centered directly over the sensor tip. Then move the object continuously over the v-groove of sensor stand. For storing readings, please r efer to section 5.5.1.

5.4.3 Delete Readings
