Inductive (position) sensors are passive devices that require an active electronics - a measuring amplifier or signal conditioner - based on carrier frequency technique.

Carrier frequency technique is the ideal way of operating inductive, resistive and capacitive sensors. It features low noise susceptibility, high signal stability and low temperature drift. The amplifier generates the sensor excitation (e.g. 5 or 10 kHz) and converts the sensor return into a proportional DC output.

MESSOTRON develops and produces a wide range of measuring amplifiers / signal conditioners. These are available in various versions as module, plug-in board, or in field or desktop housing.

Standard output signals are 10 V or 4 … 20 mA. Digital interfaces, being of increasing importance, are also available as option. Our amplifiers are designed for industrial applications and to work under harsh conditions in testing fields. We pre-adjust the amplifiers ex-works for the sensor they shall operate with. In-field adjustment is thus limited to minor tuning.
