ORP Transmitter with 4-20 mA Galvanically Isolated Output Hanna Instruments HI8615

Two-Wire ORP Transmitters

HI 8615 is 2-wire water-resistant transmitter specially designed for long distance measurement of pH in industrial applications.

Two-wire transmitters are widely used for process control in industry. These instruments are particularly useful in industrial conditions where electrical interference is an important factor

By galvanically isolating the signals, any interference created is prevented from reaching the transmitter. Industrial environments are often associated with corrosive conditions, therefore any instrumentation used must be resistant to liquids and corrosion. Hanna transmitters meet all of these criteria and they only use two wires which reduces costs and eliminates the need for an expensive coaxial cable. Two-wire transmitters are ideal when used in remote applications that do not have AC power available.
