HI 8614N pH transmitter |
|
|
The HI 8614N pH transmitter transforms the voltage signals of pH electrodes into a 4-20 mA normalized signal. The HI 8614N pH transmitter is powered by means of a power supply loop, so the device is used as a two-wire transducer. Therefore, the HI 8614N pH transmitter only needs two-wires to be connected. The temperature compensation is setup through a resistance or automatically by means of the HI 76608 optional temperature sensor. To get an accurate measurement the electrode input has been galvanically isolated. The IP 65 protection allows the HI 8614N pH transmitter to be used in adverse industrial environments. Transducers are required when the pH electrode cannot be directly connected to a regulator or to an indicator at the measurement place. Since the pH electrodes cable cannot be longer than 10 m, transducers are are used for longer distances. Transmitters convert the signal, so this signal can be transferred at greater distances.
