1. Figure 3 Circuit diagram of the isolated switching amplifier MK 13 P Ex0 24 V DC K15 The flow meter outputs a digital signal that is processed further in the isolated switching amplifier Since the signals are transmitted using an impressed electrical signal only two wires are needed in the transmission cable to transmit the signal From the electrical signal the isolated switching amplifier generates the positively switching output signal PNP signal and the inverted positively 10 Low Signal lt 2 7 mA High Signal gt 3 7 mA switching output signal PNP signal Normally the signal processor only needs the standard signal generated see figure 3 and figure 4 the inverted signal is only processed in special cases That is why the inverted signal is only shown in the circuit diagram as a dotted line One volume measurement 1V Figure 4 Signal output of the isolated switching amplitier Note Signal VSE measurement Inverted signal Note that the signal output of the isolated switching amplifier is a PNP signal low signal open output high signal U Problems may arise when the signal processor has high impedance inputs especially in the higher range of flow rates The signal edges become rounded and the signal processor cannot detect the digital sign2.
