2-wire transmitter
for pH Type 202701/10
for redox  Type 202701/20

On the output side the 2-wire transmitters have a connection for supply and standard signal. Zero and slope of pH combination electrodes are adjusted at the indicator /controller. No calibration is required for redox electrodes. The 2-wire transmitter is screwed directly on to the electrode head of the combination electrodes. This circuit arrangement largely prevents interference from dirt, humidity, or electrical fields from live conductors. A conventional coaxial cable or a 2 wire cable with screen is sufficient as connection between the transmitter and the indicator. This permits trouble-free transmission over larger distances between the transmitter and the indicator. An isolated supply is recommended when operating the transmitters with a PLC.

Type 202701 for pH
The 2-wire transmitter converts the high-impedance signal of the pH electrode (up to 1000MOhm) into a standard 4—20 mA signal.
Type 202702 for redox
The 2-wire transmitter converts the signal of the redox electrode into a standard 4—20 mA signal.
