LVDT DISPLACEMENT SENSORS
Standard and customized displacement and position sensors with measuring lengths up to 200mm
LVDT stands for Linear Variable Differential Transformer. The LVDT is an analog and non-contact sensor. With one primary and zwi secondary coils. The linear movement of the encoder rod generates an electrical signal. Attached to the encoder rod is the ferromagnetic core. The core induces a voltage in the secondary coils.
A measurement amplifier or also called signal conditioner converts the induced voltage into a standard-compliant output signal, for example 0- 10 V or 4-20mA. Here, the measuring amplifier can be integrated or supplied in an external top-hat rail housing.
Advantages of the LVDT:
Absolute measuring principle (position always available).
Non-contact measuring principle, maximum service life.
Very low linearity deviations.
Very high resolution with internal/external signal conditioning.
Insensitive to external disturbances.
High protection class (IP 68)
Mechanically very robust against external influences.
Areas of application:
From automation to process assurance and quality assurance in industrial plants, LVDTs are used. Under adverse conditions, for example with water, aggressive chemicals or high temperatures. In machines, equipment, hydraulic cylinders and valves. But also in plants and equipment for food production.
We also realize customer-specific solutions adapted to the areas of application.
