MiniTest FH Measuring Principle
Simple controller interface

MiniTest FH uses a Hall element to capture variations in the electromagnetic field and converts them into at thickness value.

  • Thickness is determined by measuring the distance of a reference ball or other reference object to the sensor tip.
  • A powerful magnet attracts the reference ball to the sensor and holds the ball in exact place on the sensor tip.
  • The magnetic field varies according to the distance between target ball and sensor tip.
  • The variations of the magnetic field increase with the distance between target ball and sensor tip getting smaller. The variation can be taken as a reference for the material thickness of the sample to be measured.

MiniTest FH Sensor Options
Measuring stand

Spring loaded measuring stand
All sensors, excluding the 90° version, come with a spring-loaded measuring stand included in the package. This stand serves the purpose of securing the sensor in an upright position, facilitating the precise measurement of objects by guiding them comfortably over the sensor tip.

Special FH4 features 1mm ball or Wire reference

FH4-1

In addition to its standard applications, the FH4 sensor is available in specialized versions tailored for specific measuring tasks. Particularly in the medical sector, where measuring small parts with narrow passages is common, the FH4-1 sensor type is ideal. This variant is designed for tasks like measuring the wall thickness of tubes, artificial organs, stents, infusion sets, etc., using a target ball with a diameter as small as 1 mm.

FH4-Wire

Certain applications pose challenges that preclude the use of measuring balls, often due to the risk of irretrievability within the object being measured. In such cases, the FH sensor offers a unique solution in the form of the FH4-Wire sensor. This variant employs a measuring wire instead of a ball, making it indispensable for testing turbine blades, where the wall thickness can be accurately determined against a wire inserted into the cooling holes.

Small tip FH2 sensor

FH2 Sensors
The small tip FH2 sensor is used for measuring in small spaces and areas that are difficult to access.

Like the bottom cavities of pet bottles and small components with a difficult to access geometry. 

Replaceable caps Repleceable tip caps for heavy wear applications
For situations where ther is a lot of wear to be expected on a measuring tip, a sensor with a replaceable wear tip is available
90 degree sensors 90° sensors for hard to reach area's
The FH2 and FH4 sensors are also available in a 90° angle version for acces where standard sensors are not able to measure. Angled sensors are technically similar as their straight versions.
