Two-Wire pH Transmitters

HI 8614 is a 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 the 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 reduce 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.

FEATURES/BENEFITS

Automatic Temperature Compensation (ATC)

Temperature compensation is performed by the transmitter’s ATC (Automatic Temperature Compensation) circuitry when measurements are taken with a temperature probe attached; if ATC is not required, it is also possible to substitute a fixed resistor for the temperature probe.

IP Protection

The unit is enclosed in a protective casing conforming to IP 65 standards.

Flexible for Your Needs

The transmitter can be connected to any Hanna controller that accepts analog input.

Easy Calibration

Calibration is performed by the adjustment of two independent trimmers — slope and offset.

BNC Connector

The transmitters use a universal BNC socket for quick and secure connection to any electrode with a BNC connector.

Isolated Input

The input is isolated from the current loop to eliminate problems related to ground loop, low insulation cables, multiple electrode connections, and a common mode voltage of up to 100V ensures true differential readings

Version with LCD

HI8614”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.

Easy Installation

HI8614 is very easy to install, wall mounted transmitter. It is supplied with 4 mounting screws
