Wide variety of models for customer-specific applications
 

What is the measuring principle of LVDT (Linear Variable Differential Transformer)?

LVDT principle are constructed with a primary and two secondary coils, arranged symmetrically to the primary winding. An electronic oscillator supplies the primary coil with an alternating current of constant frequency (between 1~10 kHz) with a excitation voltage (AC) of a few volts.

 

As a measurement object (a rod shaped magnetic core) is moved within the differential transformer.

 

Depending on the core position alternating voltages are induced into the two secondary windings. If the core is located in its "zero position", the coupling of the primary to both secondary coils is equal giving zero output.

  

 

Movement of the core within the magnetic field of the coil causes a higher voltage in one secondary coil and a lower voltage in the second coil. The difference between the two secondary voltages is proportional to the core displacement. Due to the differential design of the sensor, the LVDT series has very stable output signal for good performance.

Universal confocal controller with one and two channels                                                         Product Technology
 
 
 

The confocalDT 2465 and 2466 confocal controllers are used for fast, high-precision distance and thickness measurements and achieve resolutions in the nanometer range. These multi-peak models simultaneously measure the thickness of up to 5 transparent layers. The controllers are characterized by high luminous intensity combined with a high measuring rate of up to 30 kHz. This enables high signal intensity even on dark or rough surfaces. The fast exposure control perfectly compensates for changing surfaces.

The controllers are available as a single-channel model (IFC2465) or as a dual-channel model (IFC2466). As they are compatible with every IFS sensor, the controllers reliably solve numerous measurements tasks.
