Conductivity Switch Amplifier
Description
This signal conditioner provides the AC measuring voltage for the levelsensing electrodes. 1-channel signal conditioner, 24 V DC supply (Power Rail), Level sensing input, Adjustable range 1 kΩ .. 30 kΩ, Relay contact output, Minimum/maximum controlpa. Once the measured medium reaches the electrodes, the unit reacts by energizing a form C changeover relay contact. The module is voltage and temperature stabilized and guarantees defined switching characteristics. An electronic holding circuit is used that allows minimum/maximum control. Since the conductance of the media may vary, the relay response sensitivity is adjustable. The normal output state can be reversed through the mode of operation switch S1.
