The rugged standard carrier frequency-measuring amplifiers are available as plug-in cards for 19” module racks or in protected (IP65) field housings.
All MESSOTRON CF-measuring amplifiers can be used for operation of inductive displacement sensors in differential inductor circuits (half bridges) and differential transformer circuits (full bridges, LVDTs). On the output side, the measurement value is provided through a 10 V voltage interface or 4...20 mA current interface which is standardized in accordance with DIN IEC 60381.
The measuring amplifiers are preset at the factory and can be readjusted in the field without a special tool.
