AX416/100900/STD ABB Bailey

Product Dimensions：

The AX416 is a versatile analyzer that allows for the simultaneous measurement of two separate points. It is housed in a robust enclosure and features a large, back-lit liquid crystal display (LCD) that can show multiple parameters at once, such as pH, temperature, and alarm status. The unit is designed to work with ABB’s high-quality glass and antimony pH electrodes, as well as Redox sensors. The internal software includes advanced self-diagnostics and sensor-monitoring capabilities, ensuring that the system identifies fouling or sensor failure before it impacts the process.

Product Parameters

• Model Series: AX400 Dual Input

• Input Configuration: Two independent inputs for pH or Redox (ORP)

• Power Supply: $100 \text{ V}$ to $240 \text{ VAC}$, $50/60 \text{ Hz}$ (Standard version)

• Measurement Range: 0 to 14 pH and -2000 to +2000 mV for Redox

• Temperature Compensation: Automatic or manual using Pt100 or Pt1000 sensors

• Analog Outputs: Two isolated $4-20 \text{ mA}$ current outputs, fully programmable

• Relay Outputs: Three high-quality SPDT relays for alarms or control functions

• Enclosure Rating: IP66 / NEMA 4X (suitable for wall, pipe, or panel mounting)

• Language Support: Multi-language menus including English, French, German, and Spanish

Product Advantages

One of the standout advantages of the AX416 is its Cost Efficiency; by using a single analyzer for two measurement points, users significantly reduce the cost of ownership and installation space. The User-Friendly Interface features easy-to-follow prompts that guide the operator through calibration and setup, reducing the likelihood of human error.

The analyzer also boasts Advanced Sensor Diagnostics, including glass impedance monitoring to detect broken or aging electrodes. Its Flexible Control Logic includes PID control capabilities, allowing the unit to manage dosing pumps or valves directly for pH neutralization. Additionally, the High Environmental Protection rating ensures the device remains operational even when exposed to hosedown procedures or corrosive atmospheres common in chemical plants.

Important Considerations and Precautions

When installing the AX416, it is vital to ensure that the Signal Cables are routed away from high-voltage power cables to prevent electrical noise from causing fluctuations in the pH readings. The Electrode Maintenance schedule must be strictly followed; while the analyzer has diagnostics, it cannot correct for a physically dirty sensor. Regular cleaning and buffer calibration are required.

Regarding the Enclosure Installation, ensure that the cable glands are tightened correctly to maintain the IP66 seal, as moisture ingress is the leading cause of electronic failure in these units. Furthermore, the Grounding (Earthing) of the liquid being measured is essential for stable readings; in plastic pipe systems, a grounding ring may be necessary to eliminate stray currents that can bias the pH measurement.

Product Applications

The ABB AX416/100900/STD is primarily used in water-intensive industries and chemical processing environments.

• Water Treatment: Monitoring influent and effluent pH in municipal water plants to ensure effective coagulation and disinfection.

• Wastewater Neutralization: Controlling the addition of acids or bases to industrial waste streams to meet environmental discharge permits.

• Steam Power Plants: Monitoring high-purity water and boiler feed water to prevent corrosion of expensive turbine components.

• Chemical Industry: Precise monitoring of pH in batch reactors and cooling towers to prevent scale formation and ensure product quality.

• Food and Beverage: Managing the pH of process water and CIP (Clean-in-Place) solutions to ensure safety and hygiene standards.
