Gas Sensors ATI Q46R ORP Monitor

Sealed Reference System, for Longer Sensor Life!

Measurement and control of pH is important in a wide variety of industries. Water and wastewater, boiler feed water, high purity water, food processing wash water, chemical plant cooling water, and many other aqueous systems require reliable pH monitoring. ATI’s Model Q46P pH water quality monitor provides the combination of durability, accuracy, and versatility required for virtually any pH monitoring or control application.

ATI’s Q46 platform represents our latest generation of monitoring and control systems. Control features have been expanded to include an optional 3rd analog output or an additional bank of low power relays.

AUTOMATIC SENSOR CLEANING!
A Blast of Air Keeps the Auto-Clean Sensor Clean!

ATI’s Q-Blast option provides the ideal answer for automatic pH sensor cleaning. Employing a unique “air-blast” cleaning method, sensors can be cleaned as often as necessary without operator attention. Pulses of pressurized air delivered through a nozzle at the tip of the sensor remove accumulated solids from critical sensing surfaces, resulting in accurate and reliable measurements.

The Q-Blast Auto-Clean assembly is housed in a NEMA 4X enclosure suitable for indoor or outdoor use. The system includes an integral compressor and air-pulse control components, with a power supply for the entire air supply system incorporated into the design. A simple connection to the Q46P monitor provides the sequencing for the system and allows the operator to select cleaning frequencies as often as once every hour to as little as once every 999 hours. To insure performance in extremely cold conditions, a thermostatically controlled heater is included in the assembly, allowing operation down to -40°C.

ATI's Q46P Monitors Provide a Wide Variety
of Options to Adapt to Your Application Requirements!

CONVENTIONAL SENSORS

There is no single pH sensor that fits every application. Sensors designed for harsh environments do not necessarily work as well in high purity water. Understanding the difference between various sensor types will help you choose the best sensor for your application.

The most widely used pH sensors contain a hydrogen ion sensitive glass measuring electrode and a silver/silver chloride reference element. The reference element is sealed inside the sensor body filled with an electrolyte and electrically connected to the outside solution through one or more porous reference junctions. The glass electrode is in direct contact with the measured solution.

Conventional sensors are a good alternative for clean water applications with conductivity above about 50 microsiemens (μS). They typically provide an operating life of 1-3 years depending on the application and are relatively inexpensive. They are available in submersible or in-line versions and a clear flowcell is also available. Maximum cable length is 25 feet (7.7 m) for this type of sensor. A preamplifier in a NEMA 4X enclosure is available for applications requiring longer distances between the sensor and monitor.

PRODUCT FEATURES

Sensor Options

Choice of either “differential” or “conventional” pH sensors. Differential sensors provide reliable, long lasting service in demanding applications while conventional sensors provide a lower cost alternative for clean water applications.

Auto-Cleaning

Automatic “Air Blast” sensor cleaning system available for reducing maintenance in applications where sensor fouling is a problem.

Calibration

Automatic buffer recognition simplifies calibration.

AC or DC Power Options

Power options include universal 100-240 VAC or 12-24 VDC.

Analog Output Options

Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for pH/ORP and temperature.

PID Output

Standard PID control function assignable to one analog output.

Digital Communications

Available for either Profibus-DP, Modbus-RTU, or Ethernet-IP.

Relay Contacts

Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.

Flexible Mounting
NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.

Clear Display

Back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display provides additional information and programming prompts.

Notes:

Auto-Clean Systems are supplied with 30 ft (or 60 ft) of air tubing depending on the cable length of the sensor selected.
Pipe mount requires 2" U-bolts
When ordering a cleaning system, you must select an additional 3 low power relays
Insertion and Sanitary Mounting Styles must use 316SS Body Material. The 316SS material is ONLY available with the Insertion or Sanitary Mounting Styles.
Notes for Sensor Style: Convertible Style, PEEK, with connector & Mounting Style: Convertible with quick disconnect receptacle.
Sensor with integral connector is not waterproof. Use for indoors only.
Requires Sensor Cable (03-0029).
