The 4 ... 20mA output signal is in proportion to the height of the magnetic float. Function description The flow data sensor ZE 3075 emits a 4 ... 20mA signal generated by the height of the float in the flowmeter (DFM). The unit comprises a reed chain, the respective evaluation and implementation. The float of the flowmeters is fitted with a permanent magnet. The float travels along the reed chain by the flow of the medium. The individual contacts of the reed chain are actuated in accordance with the height of the float. The measured values are emitted as a 2-wire current signal 4 ... 20mA. This signal can be directly further processed. Actuation Actuation is through the magnet in the float of the ASV flowmeter. Mounting direction vertical installation, ASV logo on top. Connection cable The unit is connected with a commercially available unshielded cable. Where electro-magnetic interference above the EN 61326 test values for industrial areas is to be expected, we recommend the use of a shielded cable.
