Transducers and frequency dividers
The TU 7055 transducers convert the frequency output signal of flow sensors to analogue signals. The instruments are calibrated at the factory to the pulse rate of the desired sensor and tested. The current output delivers a flow proportional output signal of 0(4)...20 mA and the voltage output delivers a flow proportional output signal of 0...10 V.
If the output frequency of a flow sensor is too high for a subsequent evaluation device, then the TU 7052 can be used. It converts a sensor‘s high output frequency into one low enough for the subsequent device to process. The division ratio is freely adjustable within a range of 1:1 to 1:999.
